Impact of DFIG on low-frequency oscillation characteristic of power system
摘要
Abstract
The increasing of installed capacity of wind power has a more significant impact on the operation of power systems.Therefore, the influences of the wind power on the low-frequency oscillations of power systems have become an important issue concern to insure the stable operation of power gird .This paper sets up a complete three-machine nine-bus power system model , and uses the improved FastICA and Prony algorithms to research the influence of the doubly fed induction generator ( DFIG) on the low-frequency oscillation in power system .The results show that the ac-cess of DFIG introduces a new mode of low-frequency oscillation .In addition , the damping characteristic of the oscil-lation mode vary from the DFIG ’ s increasing access capacity to different access positions .关键词
