풍력 발전시스템의 피치제어를 위한 PID 제어기 설계

Abstract

Control plays a very important role in modern wind turbine systems. In fact, wind turbine control enables a better use of the turbine capacity as well as the alleviation of aerodynamic and mechanical loads that reduce the useful life of the installation. This thesis suggests PID controller method in order to regulate the generator power above the rated wind speed. In order for designing PID pitch controller, we use the two mass drive train model and the pitch control system based on the simple single-degree-of-freedom(single DOF) model and then verified the reasonability about the designed PID pitch controller. We use the Matlab/Simulink for the simulation and verification. Also, this model is based on the 5MW class wind turbine.
