摘　　要：针对风机接入电网对电力系统稳定性的影响,提出了一种利用相关分析的快速估计风电接入对系统关联程度影响的新方法,即通过创建风电机组模型研究风机转速与风速关系。仿真案例表明,采用该方法可以快速、有效地分析不同类型风速、不同接入地点风机对电力系统相关性的影响。Aiming at the influence of fans connected to the network on the stability of electric power system, this paper proposes to estimate the influence of the connection of wind power on the system relevance by correlation analysis, a method which studies the relation between fan＇s rotating speed and wind speed by establishing the model of fan units. Simulation example shows that this method is able to rapidly and effectively analyzes the correlation influence of fans under different wind speed and at different access point on electric power system.
