摘　　要：针对风电场在抗台风模式下系统存在容性无功电流过大问题,提出了一种备用电源并联电抗器参数优化方法。文章分别通过两种方式对并联电抗器的参数值进行确定,首先通过理论计算得到一组计算值;然后建立风电场在抗台风模式下的Digsilent系统模型,对其各种工况下进行仿真,观察仿真结果得到另一种仿真数值。比较验证表明,两者的误差很小,可为风电场抗台风模式下电力设备参数值的选取提供参考。According to reactive power problem of wind plant farm under anti-typhoon operation,it established a system model.The model is composed of many equipment models：standby power,shunt reactors,power transformers,buried cables and wind turbines equivalent model.Then power parameters of the electric models are calculated,so shunt reactor parameter optimization method is proposed.In this paper,the parameter values of shunt reactors are determined by two ways：Firstly,the theoretical calculation formula is used,and a set of theoretic calculation values are obtained by theoretical calculation.Then,the wind farm system model of Digsilent is established.Under various working conditions,observe simulation results of another set values.The comparison shows that the error between them is very small,so it provides a reference means about selecting wind farm device parameter for future.
