为了降低风电并网运行时对电力系统电压稳定性的影响，建立了风电场主流风机——双馈电机数学模型和含风电场的电力系统模型，研究了风电场功率因数cosφ和线路参数R/X影响电力系统电压稳定性的规律．最后运用Matlab/Simulink软件中信号源模块进行了仿真．仿真结果表明，风电场以功率因数为0.8、并网线路参数为0.3时，电压波动较小，保证了风电并网运行时电力系统的稳定性．研究结果为实际风电电网建设提供了理论依据．

In order to reduce the impact of wind power integrated operation on the voltage stability of power sytem, this paper sets up a math model for mainstream draught fan-doubly fed motor of wind-power station and its power system model, studies the law that the power factor of wind power station and the circuit parameters exert an influence on the voltage stability of power system, and finally performs a simulation by applying the signal source module of Matlab/Simulink software. Simulation results show that the voltage fluctuation is lower when the power factor of wind-power station is 0.8 and the parameter of transmission lines merged into the main is 0.3, thus ensuring the stability of power system while the wind-power merged into the main gid, and offering a theoretical basis for the construction of real wind-power grid.
