摘要
云广±800kV直流换流站内交流滤波器组容量大、投切频繁,其控制策略的优劣将直接影响到直流系统、甚至整个电网的稳定运行。分析了云广直流系统用于控制滤波器投切的无功控制、电压控制和谐波性能控制,并讨论了双套直流站控系统故障情况下滤波器由极控接口屏6MD66进行控制的参数设定原则及实现方法。针对云广直流工程试运行期间滤波器控制出现的问题,提出了相关的优化控制逻辑建议。
The AC filter groups at converter stations of Yunnan-Guangdong ±800 kV DC project are characterized with large capability and switching frequently,and the control strategy for them is meaningful to the stability of the DC system,even the whole grid.This paper analyzed the reactive power control,voltage control and harmonic performance control for the AC filter groups switching of the DC project,and discussed the principle of parameters setting and performance of the AC filter groups with 6MD66 in the pole control interface in the case where two station control systems failed.In order to solve the problems occurred during the trial operation of the DC project,certain suggestions to optimize the control logic of the AC filter groups are presented.
