变速恒频双馈风电系统风力机转矩模糊PID控制
Fuzzy PID control of variable speed constant frequency wind turbine system
摘要
Abstract
As the wind speed is random and uncertain,and the wind power system is nonlinear and strong coupling,only a specific set of parameters in the traditional PID control can hardly achieve the real-time speed tracking for wind turbine at different wind speeds.In the variable speed con-stant frequency (VSCF)doubly-fed wind power system,the characteristics of wind turbine are nonlinear and the moment of inertia is great.According to the maximum wind energy tracking fea-tures,the fuzzy PID control strategy for wind turbine speed tracking below the rated wind speed was presented,so the wind turbine can operate at the best torque.Control effect of the fuzzy PID was verified through the simulation.The results show that it can achieve good control effect in the speed control of wind turbine nonlinear system.关键词
