摘　　要：大量风电场并网运行将会影响电力系统的静态电压稳定性,不同的风机类型对系统电压稳定有着不同的影响。本文建立了普通异步发电机和双馈异步发电机的静态数学模型,介绍了风电场节点在潮流计算中的处理方法,利用连续潮流计算得到风电场关键节点电压随节点有功负荷变化的P-V曲线,比较系统接入风电场前后和接入不同风机类型时的系统静态电压稳定极限,并分析了风电场的接入点和风速对负荷参数和崩溃点电压的影响。The static voltage stability of the power system are affected by a large number of wind farms integrated to the grid.Different types of turbines have different effects on the voltage stability of the system.A static mathematical model of the normal asynchronous generator and doubly fed induction generator were established.Meanwhile the method of calculation of wind farm node in power flow was analyzed by using the continuous flow.The P-V curve of wind farm’s key node voltage was calculated.System static voltage stability limit of wind farm with different types of turbines were compared.The impact of access point of wind farm and wind speed to the load parameters and collapse point was analyzed.
