The Semiconductor Self-Excitation System of Synchronous Generator with Fuzzy Voltage Controller

The synchronous generator voltage control system with a synthesized fuzzy voltage controller has been described. The controller has been synthesized with the use of mathematical model taking into account the nonlinearity of synchronous machines and semiconductor converters in the excitation system. This distinguishes it from the traditional excitation controllers whose synthesis is based on the use of simplified linearized models. The mathematical modeling results allow the researchers to compare the control characteristics in the system with the proposed fuzzy voltage controller and in the system with traditional voltage controller.
