China’s power generation mainly relies on thermal power.
As China’s coal reserves rank first in the world, it has sufficient conditions for the development of thermal power. Next is hydropower, mainly in the south and southwest, then nuclear power, and finally wind power.
Thermal power generation is a power generation method that uses the heat energy generated when combustible materials are burned and converts it into electrical energy through a power generation device. Due to the shortage of fossil fuels on the earth, humans are trying their best to develop nuclear power generation, nuclear fusion power generation, and high-efficiency solar power generation, in order to ultimately solve the energy problems faced by human society. The earliest thermal power generation was realized in the thermal power plant at Gare du Nord in Paris in 1875.
Wind power generation
Converting wind energy into electrical energy is the most basic way of utilizing wind energy. Wind turbines generally consist of components such as a wind wheel, a generator (including devices), a deflector (tail), a tower, a speed limiting safety mechanism, and an energy storage device.
The working principle of a wind turbine is relatively simple. The wind wheel rotates under the influence of wind, and it converts the kinetic energy of the wind into the mechanical energy of the wind wheel shaft. The generator rotates and generates electricity driven by the wind turbine shaft.
The wind wheel is a wind collecting device. Its function is to convert the kinetic energy of the flowing air into the mechanical energy of the rotation of the wind wheel. Generally, the rotor of a wind turbine consists of 2 or 3 blades. In wind turbines, there are three types of generators that have been used, namely DC generators, synchronous alternators and asynchronous alternators.
