Introduction was made to the impact on power system stability after wind farm connection to power grid operation. Com-bined with actual situation of Sanmenxia area grid, this paper established the relevant system element mathematical model based on speciifc calculation example data. The model simulation was combined with data analysis to research on the stability of wind-hydro-electric 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 signiifcance for Sanmenxia area grid dispatching.
