摘要:

针对高岭换流站绥中电厂由东北侧交流电网改接到华北侧交流电网的情况，通过无功功率平衡分析和潮流计算，从理论上校核了东北侧的无功配置情况，并发现原交流滤波器设计已无法满足换流站的运行要求。对其新增的两组SC电容器共用一个断路器控制的特殊设计，提出了新的无功控制策略。后通过现场试验验证了新的无功控制策略可行有效，新增滤波器能满足高岭换流站大负荷运行的无功消耗。

Abstract:

On the condition that Suizhong power plant is connected to the North China side AC network from the Northeast side AC network in Gaoling converter station, theoretically, the northeast side of reactive power disposition and AC filter design are checked by reactive power balance analysis and flow calculation, which has been unable to meet the requirement of the operation of the converter station. This paper proposes a new reactive control strategy for the special design of the new two SC capacitors controlled by one circuit breaker. Subsequently, the feasibility of the new reactive power control strategy is verified by field test. The new filter can meet the needs of large load operation Gaoling converter station.

Key words: HVDC RPC control strategy converter station AC filter
