摘要

以我国实际电网为例，研究大型风电场对送端电网暂态稳定特性的影响规律。研究表明，由于风电机组本身不存在功角同步的问题，在送电通道功率不变的情况下，风电接入后系统的暂态功角稳定性有所改善，但导致系统的暂态电压稳定性变差。静止无功补偿器(static var compensator，SVC)有利于提高送端电网的暂态功角稳定性和暂态电压稳定性。

Abstract

Taking a actual power grid in China as example, this paper studies the influence of large wind farm on the transient stability characteristics of sending-end power grid. The research results show that the wind power does not have the problem of the synchronization, thus when the power flow is constant, the transient stability of the power system is improved after the wind power connected, but the transient voltage stability of the system becomes worse. Static var compensator (SVC) can be used to improve transient power angle stability and transient voltage stability of sending-end power grid.
