摘要
机组在发生电网故障时,为了保证风机能够快速收桨以保证风机安全,变桨系统配备了一套由超级电容组成的备用电源。分析了变桨系统超级电容的布置方案,对风电机组电网故障工况进行了仿真计算,得到了2 MW风电机组的超级电容的容量和型号,同时对风电机组变桨系统的电容自检策略进行了分析,并在风场运行中进行了验证。
When the grid fault occurs,in order to ensure that the pitch system can be quickly to feather,the pitch system equipped with a spare power supply composed of super capacitor.This article analyzes the layout scheme of pitch system of super capacitor,on wind power grid fault condition to carry on the simulation computation,get the super capacitor of 2 MW wind turbine capacity and type,furthermore,self checking control of super capacitor are analyzed,and verified in wind field.
