In general, generators convert mechanical energy into electrical energy. In hydropower, the mechanical power source is aberration, and the mechanical power source changes according to the power generation location. For example, a generator mounted on an electric vehicle is an electric motor. When operating a generator by an electric motor, the capacity of the electric motor must also increase according to the capacity of the generator.
