Simulation Of The Dynamic Model About Wind Turbine Generator System And Research Of Control System

With attachment importance to energy source scarcity and environment pollution ,the wind power generation system(WPGS) has developed dramatically all over the world.How to enhance operation effectively and use the wind energy becomes important matter about the technology of the wind turbine generator system(WTGS). So the simulation of the model of WTGS provides a necessary condition for the operation of WPGS effectively.The dissertation research the basic theory of the WPGS,according to the mathematics model of the speed of wind ,the wind turbine ,double-fed induction generator(DFIG) ,build simulink model in Matlab.Based on the basic theory of DFIG on electric and magnetic relation and coordinate transformations,research basic variable and transformation relation and movement of energy.Simulink the situation of operation of WTGS in variable speed of wind and analysis it,and thoroughly research the control system of WTGS about pitch control.
