Modeling of a nonlinear hydro power plant and analysis with PID controllers

Abstract

Modeling of a nonlinear hydropower system and control with different types of PID controllers is discussed in this paper. Earlier first order model of hydro power plant discussed by severally but with sudden load changes and nonlinearities of hydropower system affect the system. Nonlinearities of hydropower system are discussed in this paper. External disturbances due to load changes are introduced to the system. The dynamic analyses of system with different type of PID controllers have been carried out to test the robustness of system.
