摘要：

There is a disadvantage of frequency pitch regulation with the traditional coordinate PID power control. In order to reduce the pitch regulation, this paper proposes a wind turbine active power control algorithm. A pitch inactive zone was obtained by analyzing the power characteristic of wind turbine, and a compensator of rotor speed error was designed based on the pitch inactive zone, to complete the wind turbine active power control. At last, the proposed active power control, the traditional PID control and the power control method coordinating the rotor speed and pitch angle regulation were compared by a 5 MW wind turbine in a simulation platform. The simulation results show that the proposed control algorithm can satisfy the wind turbine goal of MPPT (maximum power point tracking) and power limit control, reduce the pitch regulation, and be easily used in engineering. © 2020, Harbin University of Science and Technology Publication.
