Research of Wind Power Control System Based on Feedforward and PID Control Technology

In this paper,the constant speed control system of hydraulic control frequency stabilization based on feedforward and PID control technology is researched,compared with the situation that the complicated electronic converters that the traditional variable speed wind power is required need high cost.After that,this paper comes up with the composite speed control method and proceed with the field test.Through the field test,the system can ensure the constant speed output of the motor and meet the high quality power requirements.
