摘要
根据机组在高风速区和低风速区的特点,设计了变桨距控制系统,使得机组能够在低风速区实现最大风能跟踪。为了增强机组在复杂条件下运行特性,在高风速区采用了PID控制器。建立了机组的仿真模型,对不同风速下的机组的稳态和动态特性进行了仿真分析。仿真结果验证了采用方案和控制策略的可行性。
According to the wind turbine working at the high speed region and low speed region,a variable pitch control system is designed to track the maximum wind power.A robust PID controller is used to enhance the operating characteristics of the power system under complex conditions at the high speed region.The simulation model of the power system is established.Using this model,the steady state and dynamic characteristics under different wind speed is analyzed.Simulation results show the scheme is useful and the control strategy is feasible.
