How to choose a basic UPS size
Usually, a UPS (Uninterruptible power supply) or uninterruptible power supply that is currently on sale will tell the power rating of the unit as
VA, such as 600VA 700VA 800VA 1000VA (or 1kVA) up to many sizes up to 900KVA also
We are able to calculate Watt from the VA. We need to know the Power Factor (PF) of each model first. Like UPS that is used
In normal household type, Line Interactive with Stabilizer, the Power Factor (PF) is 0.6. So, let’s say it is UPS type.
Line Interactive with Stabilizer 1000VA (1kVA), we can calculate as
1000 (VA) X 0.6 = 600 (Watt)
Therefore, this UPS can support a maximum load of 600Watt. The True On-Line UPS will have a power factor at
Approximately 0.7-0.8, depending on the circuit designed by which can inquire at the company that sells the product
Cummins Generators | USA VS China
Cummins USA VS China
Astonish swordsman vs fiery dragon fighting The war of generators between Cummins made in USA and Cummins made in China generators. Who will be superior? Let’s analyze it face to face.
Cummins Made in USA (US, UK)
Advantages – Cummins generators manufactured in the US have advantages in technology. Tend to use new engines, most of which use boxes ECU controls engine operation. (Common rail) ensures high efficiency Fuel saving, low emission And environmentally friendly Note: For this type of device, use Q codes such as QSB, QSL, QST, QSK.
The disadvantage – when it comes to being a godly engine, it is inevitable that the price and maintenance cost are inevitably high. Which the price is 30-100% higher than the Chinese models of the same model. Do not brag! If it is a new device, the ordering period will be longer than expected. Another possibility is the fuel that needs high quality oil as well. The type of oil mixed with water like ours is not parked.
Cummins Made in China (under Cummins copyright only Not including Shenzhen Cummins type)
Advantages – Cummins generators manufactured in China tend to use low-tech engines than the Direct Injection type, making it cheap, easy to maintain, durable, rugged. With the Chinese production potential, it can produce a lot. Ordering takes shorter time. Cummins USA can instantly order. Note: For this type of device, the code is BT, CT, NT, KT.
Disadvantages – because it is an older engine, the fuel consumption is higher. And the exhaust will be released more (Westerners are smart), less environmentally friendly than machines from America. Important when coming from China, must have hopes of fake goods (Jake is smart)
conclude
If money doesn’t cost you Cummins USA
If you want to get good quality Cummins China products, please reiterate under the copyright of Cummins only !!

Inverter generator
What is an inverter generator?
The inverter generator (IG) is a device that has an internal combustion engine, a dynamo generator and an electronic DC-AC converter in one unit. Inverter generators must use direct current (DC) to convert to AC (which is different from normal generators where the generator will produce 3-phase power). The inverter generator will adjust and change the frequency. To a constant alternating current (AC) Usually a Sinewave wave with a THD of less than 3%. Normal DC-AC conversion is done by a SMPS solid-state microprocessor controller, where electronic circuits operate in PWM mode. The reason for using a 3-phase system is because of ripple. much lower factor than single phase
Honda EU30iS Inverter Generator, High Efficiency Inverter Generator Makes fuel economy and quieter The frequency of the voltage caused by the rotation of the magnetic field is directly related to the frequency of the rotation. For this reason, in conventional portable generators, the engine operates at a constant speed. For example, a normal 50 Hz generator in our house would use an engine speed of 3000 RPM for 2 poles or 1500 RPM for 4 poles. Its fuel efficiency is still up to half of when loaded, even when power is not supplied. On the other hand, the inverter generator, the engine can walk at low rpm, because the voltage is already adjusted. In addition, the engine does not need to run consistently at the maximum speed, it can be adjusted automatically depending on the demand for electricity, all of which makes it more fuel-efficient and quieter. Another advantage of the inverter generator is that it can be synchronized for higher power. Note You cannot just put it in a coupler. You will need A parallel adapter that allows the two machines to be in sync.
Most inverter generators in the market have low power. Since it has low wattage, it’s not suitable for home use. But with a light weight and quiet sound It is therefore a very popular choice for camping activities.

Electricity generation from gasification process
Electricity generation from gasification process (Gasification)
Gasification process (Gasification) can be used to produce energy in 2 ways, which are 1. Used through a set of temperature reducing and cleaning gas. And delivered to the Gas Engine for electricity production or 2. Entering the gas to burn in the boiler To produce steam and then to spin the steam turbine to generate electricity Or to use the heat of steam for other uses further
Production of fuel to replace fuel oil From the pyrolysis system
Gasification Gasification and Pyrolysis are related and continuous processes for converting biomass, which consists mainly of carbon, hydrogen, and oxygen into combustible gases such as carbon monoxide (CO), hydrogen gas. (H2) and methane (CH4). The process is an organic combustion with limited oxygen content. Causing incomplete burning Waste disposal process with gasification technology It starts with separating waste that can be recycled and sold, dangerous waste, non-combustible waste. And the garbage that may be exploded from the total waste After that, the rest of the waste will be processed into smaller and similar sized pieces, dried (in case of high humidity) and fed into the pyrolysis or gas burner. The fuel gas has an average calorific value of about 5 megajoules / cubic meter. Which can be used to produce energy

Biogas (BIOGAS) and energy production
Technology used in the production of electricity from biogas. (Biogas, Syngas)
Biogas (BIOGAS) can be considered clean fuel (CLEAN FUEL) without emission from combustion (ZERO EMISSION) while Thailand is an agricultural country. And there are many industries from agriculture There are raw materials that can be used to produce biogas, such as vegetable scraps from farms and gardens. Scrap from ranch Including dung Waste water and waste from agricultural product processing plants
Technology used in the production of electricity from biogas.
If considering the use of such scraps to develop into biogas Can generate more than 1,000 megawatts (MW) of electricity. The technology used in the electricity generation process from biogas Is a technology that is not complicated Can be implemented at the community level It is another way to increase income for the community. Because the by-products obtained from these organic decomposition processes may be worth more than electricity, namely organic fertilizer. And the result is a tremendous value – environmental preservation From the greenhouse gas emissions from the degradation of these waste as well.
Renewable energy from agricultural waste materials
According to the plans and policies of the Ministry of Energy that must find alternative energy
The goal is that in the next 10 years, there will be up to 25% of renewable energy by using renewable energy to produce electricity of nearly 10,000 megawatts, with sources from a variety of sources such as sunlight, wind, geothermal, water and Biogas in this amount is expected to be from biogas approximately 8001,000 megawatts and also set sub-targets From the production sources in each sector, for example, from the industrial sector (WASTE WATER & DECANTER) about 230 megawatts (according to current data with a production capacity of 156.56 megawatts), hoping to get from the livestock sector (WASTE WATER & MANURE) about 10 megawatts Watts and from agriculture (AGRICULTURAL WASTE & ENERGY CROPS) Approximately 760 MW
Generators for pig farms, chicken farms
Examples of waste from agro-industrial sectors that are biogas sources
Tapioca starch industry There is waste, waste water and oily waste. Palm oil industry has waste water and sludge. The ethanol production industry has waste water, molasses and cassava waste. For the livestock sector that should be a model for electricity generation Is a pig farm Which has medium and large size farms in many areas It is estimated from approximately 176 pig farms with approximately 3 million swine farms. Waste water and pig manure from that farm can generate approximately 10 megawatts of electricity. In the agricultural sector, the cultivation of plants used to produce Direct and post-harvest crop residues Which has very high potential, such as rice straw and corncob, sorghum, grass and weeds, both on land And water weeds, such as water hyacinths and ascetic joss, etc. Leaves and the palm oil, etc. These various debris if developed into biogas Would be able to produce at least 760 megawatts of electricity as according to the target and the solution Community biogas production That will be used to generate 500-1,000 kilowatts of electricity. If this is the case, energy sustainability along with environmental conservation will occur in Thailand.

Coal processing gasification) to be a fuel gas for generators Another alternative energy can turn coal into clean energy. It is well known that oil will run out of this world in about 50 years. As for coal, we still have to use it for at least 200 years. Coal can be a stable primary energy for us. Nowadays, generators are able to make good use of coal gas fuels, a truly bright energy future.
Sustainable energy coal
The history of coal
The first use of coal began when Indian Americans Who currently lives in the Arizona area Using coal to bake pottery made from clay Later, European settlers discovered coal in North America in the mid-1600s, although only a small amount was used at first. Because at that time still used energy, water and charcoal But coal became an important factor in the 1800s. People started using coal to produce goods and steam engines. Resulting in America becoming the number one source of energy Until the need for oil to replace
However, the use of coal must consider the environmental impact very much. Because coal use causes various problems According to many, such as smoke, dust, community health, etc. From the above reasons, technology has been developed. The use of coal while keeping the environmental impact to a minimum One solution for using coal is clean coal technology by converting coal conversion into coal gasification.
Technology for processing coal into gas gas
Coal processing technology
Coal gasification technology has been developed for a long time. With reports of the first gasification experiments since the 17th century onwards, the report states The first fuel gas production plant The gasification process was created in England in 1812 by the London and Westminster Chartered Gas, Light and Coke companies, producing gas that was known as the “Town gas” or “Water gas.” “Which means gas from the reaction of coal and steam In a gasifier
Thermal power generation with coal gas production process
The process of processing coal into gas fuels Is a part of the coal oxidation process By using the principle of combustion in an air tight condition In general, the gasification process It consists of the reaction between carbon and air, oxygen, steam or the mixture of the above substances. At temperatures above 700 degrees Celsius. That is to say, when carbon-based coal is converted into gas Resulting in various unwanted substances such as sulfur and ash compounds Is easier to be removed from the product gas When compared to the combustion process Which has a lot of air The gasification process requires heat to be used for various reactions. Most of this heat is obtained from combustion of some of the solid fuel itself. By entering the air or oxygen into the reactor Normally, the air fed does not exceed 35 percent of the required air volume theoretically. Therefore, the obtained gas has a high concentration of gas products from the process. Which results in a highly efficient gas separation or cleaning process Some gasification processes may use other heat sources from the outside. Resulting in the reduction of solid fuel loss due to combustion Including able to increase the heat value of gas products By reducing the amount of nitrogen from the air fed And carbon dioxide from combustion Which these gases, if released with a large amount of gas products Will reduce the calorific value per unit volume of the gas By gas products Or synthetic gases that can be used as fuel to generate electricity, heat, or as a precursor in the synthesis of various chemicals such as ammonia, methanol or hydrogen gas Including liquid fuel etc.

Electric wind turbines | Clean energy
Wind turbines, wind power generation, clean energy for the future of Thailand
Wind turbine
Wind energy is natural energy that can be utilized. Humans have been using wind energy for thousands of years. In facilitating life, such as sailing a cargo Rotating turbine baler The turning of a stone mill to grind seeds into flour. At present, we can use to generate electricity. Since wind power is generally available, there is no need to buy clean energy. Does not cause danger to the environment And can be used endlessly. “Wind turbine” is a device that is used to extract the kinetic energy of the wind. And transformed into mechanical energy From then, mechanical energy is utilized, that is, when the wind flows through the turbine blades Will transfer the kinetic energy to the turbine blade Causing the turbine to rotate around the axis Can use the energy from this rotation to use
Wind turbines used in Thailand from the past to the present are wind turbines, wooden turbines. Used for pulling turbine, baler into rice fields in Chachoengsao province. Windmill leaves windmill leaves Used to pull saltwater barge into salt fields Samut Songkhram Province And multi-blade wind turbines Made of metal sheet, used for pumping water from wells up into the storage tank The use of wind turbines for electricity generation is still undergoing testing and development.
Types of wind turbines
Currently, the development of wind turbine technology for electricity production has been continuously developed. Many countries around the world have paid attention Especially in Europe such as Denmark Wind turbines that have been developed will have different characteristics and shapes. But if classified according to the characteristics of the axis of rotation of the turbine will have 2 types which are
1. Horizontal Axis Wind Turbine
Is a wind turbine that has a rotating axis parallel to the direction of the wind, with a propeller perpendicular to the wind force There is a device to control the turbine to turn in the direction of the wind, called the rudder, and there is a device to prevent the turbine from damage during a strong wind such as a storm and is located on a strong pole. Horizontal axis wind turbines, including windmills, windmills (Windmills), wind turbines, leaves and silks. Commonly used with water traction machines Bicycle wheel wind turbine Wind turbine for generating electricity with propeller type
2. Vertical Axis Wind Turbine
Is a wind turbine with a rotating axis and propeller perpendicular to the movement of the wind horizontally Which can be able to receive the wind horizontally in all directions Works well with low-speed air currents. Is a technology that has been continuously developed Suitable for tall buildings in large cities
Horizontal axis wind turbines are the most widely used type. Mostly designed to be a type that drives the turbine blade with lifting force Nevertheless Vertical axis wind turbine Which has been developed a lot in the latter, has also received more attention. This is because the advantages over the horizontal axis are In the vertical axis, regardless of the direction of the wind, it can rotate Without the need for a control device so that the turbine is facing the wind In addition, the vertical axis type Generators and transmission systems are placed closer to the ground than the horizontal axis. When the problem is easier to fix than a horizontal axis stuck on a tall tower.
Components of large wind turbine systems for electricity generation
Key components Of general wind turbine systems Can be divided as follows
Electric wind turbine components
1. The propeller is a wind power receiver and transformed into mechanical energy Which attaches to the spindle and sends the force from the spindle to the spindle shaft
2. Spindle shaft which receives force from the rotor axis And transmitted through the power system To spin and spin the generator
3. The transmission room, which is a system to adjust and control the rotation speed Between the spindle shaft and the shaft of the generator
4. Engine room, which is large and important for wind turbines Used to contain various systems of wind turbines such as gear systems, generators, brakes and control systems.
5. Power generator Responsible for transforming mechanical energy into electrical energy
6. Electric control system Which uses a computer system to control the operation And supply electricity into the system
7. Brake system is a mechanical system to control the rotation of the impeller and the shaft axis of the turbine. When receiving wind speed Beyond the ability of the turbine to accept and during maintenance
8. The neck axis rotates to support the wind direction It controls the turning of the engine compartment. For the propeller to receive the wind direction by electronic system Connected to have a relationship And the rudder receives the wind direction at the top of the machine
9. Anemometer and wind direction Which connects the signal cable to the computer system To be a measure of the speed and direction of the wind So that the computer can control other mechanisms correctly
10. The wind turbine pillar is the bearing unit that is upstairs.
Wind turbine, wind turbine, renewable energy
Wind turbines and electricity generation
The working principle of wind turbines When the wind blows through the turbine blades The kinetic energy produced by the wind will Causes the turbine blades to rotate And get the mechanical energy out The mechanical energy from the axis of the wind turbine is transformed into electrical energy. By a generator connected to the axis of the wind turbine Distribution of electricity through electrical control systems And continue to supply electricity into the system The amount of electricity produced depends on the speed of the wind. Propeller length And the location of the wind turbine installation
Electrical wind turbine installation Assembly of wind turbines for electricity Installing Vertical Axis Wind Turbine 5kw Vertical Axis Wind Turbine
Wind turbines and their use
Due to the uneven nature of wind speed And the need for consistent energy to be suitable for use Must have energy storage and use reliable energy sources as a backup Or used together with other energy sources
There are many types of energy stores. Much depends on the work to be used, such as If it is a turbine to produce small power, the battery is often used as a energy storage
Using other rotating energy sources This system, usually a wind turbine, will provide power at all times with sufficient wind speed. If the wind speed is low or the wind is calm Other energy sources will provide alternative energy. (The wind turbine is the main source of energy and the other energy sources are reserves.)
Combined use with other energy sources May be a diesel engine Or hydro power from dams, etc. This system normally has other energy sources already supplying energy Wind turbines will provide power when there is sufficient wind speed. At the same time, it will reduce energy supply from other energy sources, such as reducing the use of diesel fuel of diesel engines (this system of other energy sources mainly supplies energy The wind turbine serves to supplement energy from the main energy source)

7 ways that Sun Tzu doesn't say but Thai SMEs should know
7 ways that Sun Tzu didn’t say But Thai SMEs should know
1. Learning competitors When new competitors emerge from ASEAN, SMEs need to study and learn about them. In order to be ready to face the competition. SWOT analysis to recognize competitors will help SMEs that are ready to compete. Which aside from competitors from 9 ASEAN countries There are still 3 or 6 more countries to learn (ASEAN + 3, + 6).
2. Strengthening production capacity Reduce production costs with cost management. Effectively With modern machinery and technology used in production Drive the production of more value-added products in order to avoid price competition.
3. Accelerate strengths and reduce weaknesses. Companies need to develop stronger strengths and reduce weaknesses as much as possible. To prepare to handle competitors that may enter the competition at any time
4. Commitment to customers in all forms Companies in the supporting industry or who have previously produced or sent to the parent company may be outraged by competitors in other countries that have a greater advantage as a production base. Entrepreneurs that have their own brands Should conduct commercial studies on a regular basis in order to produce products that are in line with market needs. As well as become more skilled in production skills
5. Have to think “how to make him stay with us” in order to prevent scramble for skilled labor. SMEs should look for effective human resource management strategies that will attract talented employees to remain with the company. As much as possible
6. Strengthen Solve industrial problems by integrating Supply Chain Management to transfer technology and knowledge to each other in the industry such as applying best practice of each factory to reduce costs. Solving high wage but ineffective And jointly invade the international market etc.
7. Reduce the risk by distributing orders. SMEs should have more orders spread from other sources in order to reduce the risk from any employer. One of them will reduce or cancel the order, including creating a wide network of partners both in Thailand and overseas. To increase opportunities for joint ventures in production and exports
POWER GENERATOR 5
In 2015, Thailand and ASEAN Member States will be fully integrated into the ASEAN Economic Community (AEC) through the ASEAN Economic Community Plan (AEC Blueprint) consisting of Being a single market and
Joint production base Enhancing competitiveness and equal development
Currently, Thailand has SMEs in the amount of more than 2.9 million businesses. Accounting for 99.6 percent of the total number of enterprises Employment of 10.5 million people or 77.8 percent of the total employment in the country. Create an additional 3.75 trillion baht in GDP or GDP SMEs, or 37.1 percent of the country’s economic value added.
Each year there will be more entrepreneurs every year. From now on, SMEs need to be well informed about the ASEAN Economic Community. Because other ASEAN member countries Has prepared to become an AEC by expanding trade. Expand investment in ASEAN countries together and ASEAN counterparts
Therefore, Thai SMEs need to develop their potential urgently. And prepare to support the opening of a free trade market Products must be manufactured to meet international standards. And ready to accept trade agreements that change in a kind of changing hands, doing business in ASEAN countries will be like one. Price competition, quality standards inevitably occur. Therefore, it is time for the Thai SMEs to be alert. And cooperate with consciousness and wisdom
Introduction to Engine Turbines
Gas turbines
Many people have been to the airport together. If anyone has never been At least I have probably seen the plane in the form. Or have been on television for some time For this plane, you might have seen something under both wings, more or less, depending on what the plane is. And used for what? For all of this I have told you Will lead to the mention of aircraft engines The engine that looks like this jar is called the Gas Turbines or translated into our home language. Gas turbine engine
What is a gas turbine?
Gas Turbine is an engine designed to convert energy in the form of fuels into useful energy such as shaft energy. Or the high-speed propulsion of a gas turbine. The gas turbine will consist of hot gas production and hot gas to energy conversion. Are air compressors, combustion rooms, and gas turbines The work power from some gas turbines will be used to propel compressed air. Causing the air to rise to high temperature, when burning, it will get hot gas with high pressure running through the turbine
Gas Turbine Components
Component Turbines engine
How does a gas turbine work?
Gas Turbine has basic equipment as follows
Compressor (Compressor) is responsible for compressed air coming in. To achieve high pressure And enter into the combustion chamber
Combustion chamber combustion of fuel. To increase the speed and pressure of the gas
Gas turbine transforms the energy of the gas obtained from the combustion chamber to rotation.
High-pressure gas from the compressor flows into the combustion chamber. The fuel injector in the room serves to inject fuel such as propane and natural gas etc. Because the incoming gas is at speeds of over 100 miles per hour In the combustion chamber, a device called Flame can
Combustion area
Half-cut image of a flame can
Turbine Stage
The nozzle is on the right Responsible for continuously injecting fuel The gas will run through a small hole. And an explosion Turned into a high-speed gas running to the left
To the left of the combustion chamber Part of the turbine In the picture on the left, there are 2 parts. The first part is used to drive the compressor. Which the shaft of this turbine connects to the compressor in the same shaft The second part of the turbine is used to drive the propellers of the helicopter. These two axles are not stuck together. But with the same axis Use bearings to separate movement
Types of Gas Turbine
Gas Turbine is divided into 3 types which are
Turbojet engine: Turbojet engine provides thrust by accelerating the speed of all air mass through the engine due to the speed of the air mass ejected to achieve thrust. The turbine system of the Jet engine is designed to receive The force of hot air currents or exhaust, just enough to rotate the compressor and other equipment. All the thrust (100% of thrust) is caused by the mass of the air blown out (exhaust gas).
Turbojet
Turboprop engine: Turboprop engine provides thrust by changing The energy from the mass of gas into power or mechanical energy to be used to spin the device to rotate the compressor and the propeller. The shaft or turbine shaft of the turbine is attached to the propeller. Through the reduction gear system, approximately 90% of the total thrust comes from the impeller and only less than 10% comes from the mass of hot gas or exhaust air of the exhaust.
Turboprop
Turbofan Engine: The Turbofan Fan Engine will be ahead. And has an enclosed structure called the fan duct. It is driven or rotated at the same speed as the compressor (except free turbine). If it is a free turbine, it has the same speed as the last turbine after the turbine that drives or turns the compressor. The air mass from the fan will Is pushed out from the mass of air passing through the engine or may be mixed with the air mass passing through Inside the engine At the end of the engine More than 75% of the energy or thrust comes from the mass of air from the fan and less than 25% from the exhaust gas.
Turbofan
Gas Turbine Application
1. Gas power plant Usually a generator for backup power (stand by) and helps to increase production. When the demand for peak electricity (peak load) has a capacity of 1 – 60 megawatts, in addition to being used as a power generator for electricity production Gas turbines are also used for other uses. For example, used as an engine to drive large pumps.

Generators | Diesel Diesel VS Diesel Diesel
How to choose a generator between engines | Diesel with high speed vs Diesel with slow motion?
1. Diesel generator with slow rotation: The engine speed is approximately 300-1,000 rpm
Pros: The outstanding features of this type of generators are strong, durable, slow-to-wear, as much as possible. More durable 3-4 times faster than rotary speed because it is designed especially for heavy use. With low maintenance fees, easy maintenance With a low cycle, it has a godlike feature, which is more than 30% fuel saving, plus another item of descent, which can be used to mix diesel fuel oil with fuel oil. Often found in power plants Industrial factory Resorts on various islands that the electricity cannot reach Brands of this type of generators are LISTER BLACKSTONE, ENGLISH ELECTRIC (RUSTON), MWM.
Disadvantage: Because it is mainly designed for durability, it requires high quality materials and high production time, which makes the generator price This type is naturally higher. The activation process is complicated, not suitable for use as a backup generator. The last disadvantage is the device that looks conservative, like the face of a Korean movie hero.
2. Diesel speed generator: The engine speed is around 1,000 rpm or higher.
Advantages: Diesel generators and high-speed spin are the most common generators. The engine is easy to find, cheap, versatile. There are many sizes and brands to choose from. The operation is simple and not complicated. Quickly turn it on. It is often used with ATS (auto transfer swith) to be a standby generator. And when the royal fire comes, the device can be switched off by itself Suitable for factories, hospitals, hotels, general people, counted as Generators for SME businesses. In truth, the machine looks good, like Miss Korea. There are familiar brands including Cummins, Perkons, Volvo, Mitsubishi, Nison, Hino, Isuzu, Denyo.
Disadvantages: have higher fuel consumption and maintenance costs Including a less service life compared to slow-speed generators Not suitable to be used as the main power generator
Summary: In conclusion, what kind of generator is suitable for use?
