Basic introduction of hydroelectric generating sets
The function of the hydroelectric generating unit is to convert the rivers, lakes and other places with potential energy to a low place, and convert them into mechanical energy of the turbine through the turbine. The turbine then drives the generator to generate electricity and convert the mechanical energy into electric energy.
The hydro-generator in the hydro-generator is driven by the turbine. The speed of the generator determines the frequency of the output AC. Therefore, it is important to stabilize the rotor speed to ensure the stability of the frequency. The closed-loop control can be used to control the turbine speed. The frequency signal sample of the generated alternating current is fed back to the control system that controls the opening and closing angle of the turbine vane to control the output power of the turbine to achieve the purpose of stabilizing the generator speed.
