| 摘 要： | 为实现风力发电设备核心控制器国产化,通过分析风力发电机核心控制器所要解决的主要问题、硬件选型方法和软件控制流程,对兆瓦级变桨变速风力发电机组核心控制器提出基于叶轮转速、加速度和角度PID控制的变桨控制算法解决方案.该算法保证风机在实现较高发电效率、最大功率限制的同时,跟踪并补偿风速变化带来的负荷突变,避免给风机传动链造成冲击和给电网带来谐波、闪变危害,提高风机运行的安全可靠性和发电上网的电能质量.数值仿真计算和动态模拟实验证实了该方法的有效性.

| Abstract: | In order to produce domestic controllers of wind turbine generators,by analyzing core(problems),hardware type-choosing methods and software control processing,a solution to the pitch control(algorithm) of the MW wind turbine generator controller is proposed,based on the PID control of blade's rotate speed,accelerated speed and pitch angle.This algorithm can ensure the windmill to implement high efficiency of wind power generator,maximum output limitation,and compensate the sudden load changes caused by wind speed(fluctuation) to avoid the impact on windmill driving-chain and harms,such as harmonic and flickers on power grid,and improve the safe running reliabilities of the generators and the power quality connected to the grid.Numerical simulation calculations and dynamic simulation tests show the effectiveness of this method. |
