The Study of Strategy for Synchronous Wind Power Generation with Brushless Excitation System Pitch Control

Abstract

This paper analyzed the structure of a direct-drive wind power generation, The mathematical model of the wind power generation system is complex, strongly affected by the varying parameter and exterior disturbing, and has the features of nonlinear, time changing and coupling. According to the above characteristics, the fuzzy-logic control is introduced into the wind power system. By using the fuzzy controller as the controller of the variable-pitch system. This paper carries out simulation of the controller when the wind speed is higher than the rated speed. The result shows that the controller produces good dynamic performance, good robustness and adaptability.
