Analysis of Wind Power AC Line Relay Protection for Capacitance Current Compensation
In order to further reduce the significant problem of capacitor current,a new method of capacitor current compensation for wind power AC line relay protection is designed,the new capacitor current regulation process of wind power outgoing line is analyzed,and the zero sequence differential protection of reactor grounding is studied.The results show that the optimization process can increase the difference flow significantly and has higher sensitivity than the traditional algorithm.It can effectively improve the braking effect of the zero sequence differential protection of the reactor,increase the braking force by tens of times,and obtain higher sensitivity of the zero sequence differential protection of the reactor.
