[0002] Hydropower generation is a science and technology that studies the technical and economic issues of engineering construction and production operation that convert water energy into electrical energy. The water energy used in hydropower generation is mainly the potential energy contained in the water body. In order to realize the conversion of water energy into electrical energy, different types of hydropower stations need to be built. The hydroelectric power generation system (Hydroelectric power) uses the water with potential energy in rivers, lakes, etc. located at high places to flow to low places, converting the potential energy contained in it into the kinetic energy of the turbine, and then using the turbine as the original power to drive the generator to generate electricity.
