Effect Of Wind Farm Based On Doubly-Fed Induction Generator On Transient Out-Of-Step Of Power Grid
INTERNATIONAL CONFERENCE ON MATERIALS, MANUFACTURING AND MECHANICAL ENGINEERING (MMME 2016)(2016)
摘要
To research the influence of wind farm based on doubly-fed induction generator on transient out-of-step characteristics of power grid. The single-machine infinite-bus model of wind-thermal-bundled system and a dynamic model of doubly fed wind farm are built by PSD-BPA software. The influence of proportion of wind connected, reactive power compensation, integration position and different fault point on transient out-of-step of power grid as well as the variations of thermal power angle and the action time of splitting device are investigated and compared. The conclusion is as follows: the proportion of wind connected and converters capacity are larger, wind farms have reactive power compensation, the better the transient out-of-step for wind-thermal-bundled sending system is restrained when the integration position of wind farms are in sending system.
