摘要
Abstract
As the distribution of wind farms is often far from the load center,it needs long-distance transmission to deliver wind pow-er.Series capacitance compensation technology is widely used in long-distance transmission because of its advantages of increasing power transmission capacity and enhancing power system stability.However,the increase of series complement capacitance in the line also brings potential risks to the system.In the current mainstream wind turbines,double fed induction generators(DFIG)are the most prone to sub-synchronous resonance(SSR).Therefore,it proposes a suppression strategy based on integral control to deal with the SSR caused by induction generator effect of DFIG.Firstly,it proposes a new analytical method to consider the impedance of both rotor-side converter and grid-side converter when establishing the equivalent circuit of DFIG.Secondly,it proposes a virtual induct-ance suppression strategy based on integral control.Finally,it establishes the equivalent simulation model of wind farm,and the ac-curacy of the established equivalent circuit and the proposed suppression strategy is verified by simulation.关键词
