Influence Mechanism Analysis of Large-scale Wind Power Integration on Power System Angle Stability
摘要
Abstract
With the wind scale continuously increases,the research on the influence mechanism of wind power integration on the power system angle stability should be paid attention to.Base on the equivalent external characteristics of doubly-fed induction generator (DFIG) during the period of the fault and the power characteristic equation of single-terminal delivery system,the effect of different scale wind power on the electrical distance between the sending power grid and the receiving end power grid is studied,and the influence mechanism of different scale wind power integration on power system angle transient stability under different fault conditions is researched.It is conclusion that in the condition of close distance fault and remote distance fault,system power angle characteristic improves with the increase of the wind power scale,when the wind power scale reaches a certain level,the power angle stability deteriorates,far from improving.It is proved that the analysis of impact of different scale wind power integration on power system angle stability is correct through simulation calculation of the actual grid.关键词
