| 摘 要： | 随着风电装机容量的增长,风电场接入运行对电力系统稳定性的影响不容忽视。借助单机无穷大系统分析了双馈风电机组的自身稳定性,发现双馈感应发电机转子运动没有机电暂态失稳现象,但存在电磁暂态失稳现象;研究了双馈风电场与同步电机运行在典型接线方式下系统稳定性的差异和变化。仿真算例表明,由于双馈风电机组有功功率的快恢复特性,可能使含双馈风电场混合电力系统的暂态稳定水平显著降低。

| Abstract: | The integration of large scale wind farm brings serious influence to the stability of power system.The stability of doubly-fed induction generator(DFIG) via single machine vs.infinite system is investigated at first.It is revealed that,for the rotor motion of DFIG itself,there exists the electromagnetic transition unstable phenomenon but not kinetic unstable phenomenon.Furthermore,according to the connection mode of DFIG-based wind farm and traditional synchronous generator,the transient stability of power system is compared and analyzed.Examples by simulation show that,due to the fast recovery character of the active power output by DFIG,the transient stability of hybrid system containing DFIG-based wind farm may be deteriorated obviously. |
