摘　　要：为了研究永磁直驱风电机组的低电压穿越(LVRT)特性,在实时数字仿真器(RTDS)中建立电网、风力机、发电机与变流器功率部分的模型,模型中的参数与实际机组保持一致,将风电机组主控、变流器控制器与RTDS构成硬件在环测试平台。对风电变流器控制器在LVRT时采用的关键技术进行了研究,在RTDS中模拟各种短路时电网电压跌落工况,得到风电机组LVRT期间的响应波形。基于RTDS的硬件在环实验,既可以对风电机组的控制策略进行研究、优化,又可以从电网角度检验风电机组的LVRT特性是否满足标准要求以及研究对电网的影响。In order to research the low voltage ride through（LVRT） ability of the permanent magnet direct drive wind turbine generator system,build grid,wind turbine,generator and power inverter part model in the real time digital simulator （RTDS）, the parameters in the model consistent with the actual system, the wind turbine generators main control PLC, the converter controller and RTDS real time simulator together to form the hardware in loop test plat- form.The key LVRT technologies adopted in wind power converter controller is studied, the RTDS simulate in various working condition of the power grid voltage sags,the response waveforms during LVRT of the wind turbine generator system is obtained.Based on the hardware in the loop of RTDS experiment, the wind turbine control strategies can be optimized, at the same time the LVRT characteristics of the wind generator can be verified whether meet the stan- dard requirements and the wind generator influences to the grid can be researched.
