## MATLAB风电并网对电力系统稳定性影响的研究

Abstract I In combined with the serious environment pollution problem of traditional fossil energy also depleted the grim situation, at present, represented by the wind in the countries all over the world new energy grid technology has gained rapid development. Characteristics due to the special nature of wind power, wind power at the same time makes the system such as intermittent, regional stability of all kinds of changes have taken place.
This article mainly research by small capacity wind power unit connected to the small disturbance and transient stability of power grids. First analysis of the mathematical model of doubly-fed wind power system from the understanding and mastering the model parameter is set, and based on when the same grid point source access namely synchronous generator system model of the numerical example compared to single machine infinite power system diagram example, greatly in this simple system, on the other side of the access type doubly-fed wind legal unit, through the simulation software of grid-connected wind effect of the system were studied. Then, analyze the small disturbance voltage stability of power system containing wind power mechanism, and the quantitative study Angle stability analysis of wind power after the access to the static voltage stability of power system. Using different types of stable analysis indicators, in view of the strong and the weak power system containing wind power, analysis of different wind power output, namely different wind turbines combined effect of the system. After wind power grid system are analyzed in the end, derived the expressions of the transient voltage, and to contain small system based on doubly-fed wind turbine wind farm as an example, the simulation analysis of the different scale of wind power output, the influence of various fault types such as the system transient, simulation analysis of characteristic curve and presents a corresponding conclusion.
Key words: Power System; wind power integration; small-disturbance stability; Transient Stability; MATLAB simulation software
