摘　　要：对风电场接入地区电网后的电压暂态稳定性进行了仿真研究。首先分析了电压暂态稳定的相关理论,通过实际电网的仿真计算研究了风电场接入地区电网对电压稳定性的影响,通过改变风电场接入系统的阻抗值,比较了系统电压暂态稳定性的程度,并得出地区电网在风电接入后的电压稳定性状况。仿真模型采用实际电网模型,对实际电网研究风电接入后的电压稳定性具有一定借鉴意义。The article simulates the voltage transient stability of a real power system connected with a wind farm.The article analyzes theoties about voltage transient stability firstly.Then,the article takes the mean of simulation to study the influence to voltage transient stability of the power system caused by wind farm.The impedance between the wind farm and the power system is changed to compare the voltage transient stability under different circumstances.Some protective measures are given.The simulation takes a real power system model.The process and results of simulation have some value to the relevant study in actual power system.
