摘　　要：大型风电场并网运行将会影响电力系统的电压稳定性。分别就两种主流风机(即普通异步发电机和双馈感应电机)风电场接入系统的静态电压稳定问题进行了研究。首先简要介绍了文中分析静态电压稳定问题的方法,即连续潮流法。然后分别建立了两种主流风机的稳态数学模型,分析了两种风电场静态电压稳定的特点。最后通过算例仿真,分析了影响风电场静态电压稳定的主要因素,比较了不同风机类型对风电场静态电压稳定的影响。Injection of large quantity of wind power into power system exerts large impacts on the voltage stability of the system. This paper focuses on the static voltage stability of the power system connected with large-scaled wind farms. First, it presents a brief introduction to the static voltage stability analysis method used in the paper, namely continuation power flow method. Second, it establishes mathematic models for two kinds of main wind power generators （inductive generators and double-fed inductive generators） respectively, analyzing each one＇s voltage stability characteristics. Finally, by means of simulation with ~the IEEE30-power system which is connected with a large wind farm, the paper analyzes the main factors which affect the static voltage stability of the wind power system, and compares impacts of different wind power generators on the static voltage stability of the wind power system.
