At present, the gas turbine generator set is small to a few megawatts, large-scale gas turbine power alone has more than 500MW.
● Steam turbine power plants refer to the energy stations that uses the steam turbine as the prime mover and by converting steam heat energy into mechanical energy to drive the alternator to operate to generate electric energy and heat energy. Such as Coal-fired power plants, Fuel oil power plants, Heat recovery power plants, Solar thermal power station, Nuclear power plants, etc.
Its basic production process is as following: Fuel burns to heat water in a boiler to generate steam, whereby the chemical energy of the fuel is converted into heat; then the turbine is driven by steam pressure to rotate, whereby the heat energy is converted into mechanical energy. Then the steam turbine drives the alternator to rotate, converting the mechanical energy into electrical energy
● Hydropower stations refer to the energy stations that uses the strong water flow generated by water level difference as kinetic energy to drive the turbine to convert hydraulic energy into mechanical energy, and then drives the alternator to generate electrical energy.
Hydroelectric power is the use of hydraulic power to drive the turbine to turn, and transform the water into mechanical energy. The turbine drives the alternator to generate electricity and convert the mechanical energy into electrical energy. Hydraulic power generation is the process of transforming potential energy of water into mechanical energy and then into electrical energy.
● Wind power stations refer to the energy stations that uses the wind to drive the wind turbine to convert the wind energy into mechanical energy to drive the alternator to generate electric energy. Wind energy belongs to renewable energy, pollution-free, and has broad application prospects.

2. Classification according to types of energy
The Power Plants can be classified into Thermal power plant, Hydro power station, Wind power station, Solar energy power station, Ocean energy power station, and Nuclear power plant, etc.
2.1 Thermal Power Plants refer to the energy stations that use coal, oil, and natural gas as fuels to produce electric power. Including Steam turbine power plants, Gas turbine power plants, and Engine power plants.
According to fuel classification, the thermal power plants can be divided into Coal-fired power plants, Fuel oil power plants, Gas power plants, and Heat recovery power plants.
● Coal fired power plants refer to the energy facilities that use coal as fuel and generate steam through combustion to drive steam turbine for power generation. Including equipment such as boilers, steam turbine genset, etc.
● Fuel oil power plants, including Steam turbine power plants(this only refers to the use of fuel oil as fuel to drive the steam turbine to generate power by burning the boiler), Gas turbine power plants, and Fuel oil engine power plants. Most small and medium-sized power plants use internal combustion engines for power generation.
● Gas power plants, mainly refer to gas turbine power plants and gas engine power plants. Large power plants often use gas turbines for power generation, such as CCPP and IGCC.
● Heat recovery power plants refer to the energy stations that uses various waste heat from industrial enterprises to generate electricity, including boilers, steam turbine generators, and other equipment.
2.2 Solar Power Stations refer to the infrastructure that converts solar energy into electrical energy through photovoltaic or thermal conversion technology. Including Photovoltaic power stations, Solar thermal power stations, etc.
● Photovoltaic power station refers to a facility that utilizes the photovoltaic effect of solar energy to convert light energy into electrical energy. Including solar panels (components), controllers, inverters, energy storage equipment, and maintenance facilities. The installed capacity of centralized power stations can reach tens of millions of kilowatts, while the individual capacity of distributed power stations can be as small as a few kilowatts.
● Solar thermal power station refers to a facility that first converts solar energy into heat energy, and then heats the working fluid through a collector to drive a steam turbine for power generation. Including heat collection devices and thermal energy storage systems. At present, commercial applications are dominated by photovoltaic power plants, while thermal power plants have a limited application range due to technical complexity and cost factors.

3. Classification according to usage
The Power Plants can be classified into Stationary Power Plant, Mobile Power Plant, Power Barge (Floating Power Plant) and Containerised Power Plant, etc.
3.1 Stationary Power Plants, It includes two types: basic power plant and emergency/ standby power plant, Many factors should be consider determine the type of power plant, and one of the most critical is the load factor.
3.2 Mobile Power Plant, Usually Consists by the power generation vehicle and auxiliary vehicle. It is an independent and complete power generation device or system. Mobile power plants are mainly divided into three types: automobile power station, train power station and trailer power station. and is used on many fields of urban emergency power supply, rescuing operation, emergency power supply and military equipment etc.

4. Classification according to structure
The Power Plants can be classified into the Simple Cycle Power Plant, Cogeneration Power Plant, Combined Cycle Power Plant, and Hybrid Power Plant.
4.1 Simple Cycle Power Plants(SCPP), Only for power generation. SCPP is consist of a single or multiple gas turbine (or I.C.E) driven generator sets. The main components of the gas turbine are the air compressor, the combustor and the turbine, which drives both the air compressor and an electric power generator. We can provide flexible and reliable solutions to enable the grid to respond quickly to flexible load demands. The focus is on robust operation, high availability, fast start-up as well as start reliability and the capability for quick transient load responses. SCPP are often used in remote areas as decentralized local power generation sets and as emergency or peaking units. The generating efficiency of gas turbine is about 28-38%, and the efficiency of the internal combustion engine is about 40-48%.
4.2 Cogeneration Power Plants, also known as Combined Heat and Power (CHP), refers to a group of proven technologies that operate together for the concurrent generation of electricity and useful heat in a process that is generally much more energy-efficient than the separate generation of electricity and useful heat. Both technologies CHP and CCHP are well-established, high-efficient, cost-effective and environmentally-friendly solutions. Widely used in Distributed Energy Resources projects making an important contribution to the global energy demand.
4.3 Combined Cycle Power Plant(CCPP) is the Combined cycle power generation system composed of gas turbines, generators, boilers, steam or heating type steam turbine. The system converts the waste gas discharged by the gas turbine into steam through the waste heat boiler, and then the steam is injected into the steam turbine to generate electricity, or the spent steam can be used to heating after generation.
4.4 Hybrid Power Plants(HPP) refer to a kind of power generation system combining two types of energy, which common form is hybrid power generation combined by renewable energy sources (wind power, hydroelectricity, solar energy, ocean energy, etc.) and fossil power. Renewable energy sources hybridized with liquid fuel or gas fuel engines are the perfect synergy to take the advantages of both electricity sources. The renewable energy share delivers free electricity with a green footprint and highly efficient engines care of reliable base load supply or flexibly available backup for obtaining a continuous power output.
