摘要
针对风力发电机组系统进行了特性分析及控制设计。首先,根据风力发电机组静态性能特点,采用Matlab/Simulink进行建模并仿真,结果表明在额定风速下,风力发电机能正常运行但风能利用率较低,额定风速以上风力发电机的输出功率超过其额定功率;然后,针对桨距角子系统,设计了PID控制器,通过控制风力机桨距角来实现风力发电机组的恒功率输出。仿真结果表明,PID控制达到了预期效果,并能够提高风力发电机组运行的稳定性。
This paper mainly focuses on feature analysis and control design for the system of wind turbine generator set. Firstly, an Matlab/Simulink model for simulation is established and simulation results show that wind turbine generator can run stably but there is a lower wind power utilization rate under rated wind speed, however wind turbine output power overruns its rated power above rated wind speed; and then, PID controller for pitch angle sub-system is designed to control the pitch angle to achieve constant power output of wind turbine generator. The simulation results show that PID controlling can improve the stability of wind turbine generator set.
