摘 要： 介绍了风电场接入电网运行后对电力系统稳定性的影响。结合三门峡地区电网的实际情况，在具体算例数据的基础上建立相关系统元件的数学模型，采用模型仿真与数据分析相结合的方法对含双馈风电机组风水电联合系统的稳定性进行了研究。结果表明双馈风电机组的接入降低了系统原有的阻尼，为系统引入了相关的振荡模态，分析研究成果对三门峡地区电网调度运行具有指导意义。

Abstract: Introduction was made to the impact on power system stability after wind farm connection to power grid operation. Combined with actual situation of Sanmenxia area grid, this paper established the relevant system element mathematical model based on specific calculation example data. The model simulation was combined with data analysis to research on the stability of wind-hydroelectric combined system with doubly-fed wind generator unit. The result shows that connection-in of double-fed wind generator unit has reduced original damping of power system and introduces related oscillation mode for the system. The analysis study achievement has guiding significance for Sanmenxia area grid dispatching.
           Key words: doubly-fed wind generator unit; hydro-generator unit; stability of power system; oscillation mode; Prony algorithm
