风电机组并入电网时，难免会导致电网运行的一些故障，其中的两种可能故障情形就是无功功率控制和频率调节。本文根据《大型风电场并网设计技术规范》中关于风电机组无功功率控制和频率调节的规定，利用Matlab/simulink来模拟风电机组并网时可能遇到的故障电压，分别模拟了风电机组满足功率因数在一定范围内动态可调和频率发生变化时的情形。仿真结果表明本文所设计的仿真系统能达到系统要求。

When wind turbine connected to the grid, inevitably lead to failure of the power grid operation, which the two possi-ble fault conditions are reactive power control and frequency regulation. Based on the provisions of reactive power control and fre-quency regulation of wind turbines“large-scale design and technical specifications for wind farm to grid”of china, take advantage of Matlab/Simulink to simulate the failure voltage of wind turbine to grid you may encounter. simulate wind turbine to meet the case when the power factor dynamically adjustable within a certain range and frequency change respectively. Simulation results show that the simulation system meet the designed requirements.
