Static Excitation System of Generator in Hydropower Station

Excitation system is one of the most important parts of the synchronous generators. Excitation system of the generator comprises from machines, devices and appliances that are intended to provide direct current to the generator field winding and this current regulation. For a constant frequency supply, the output voltage of the machine depends on the excitation current. In this paper, static excitation system of 10 MW synchronous generator in hydropower station is described and analyzed how the excitation current can be controlled to be stable terminal voltage and reactive power of generator.
