Research on Configuration and Switching Strategy of AC Filter for Shaoshan Converter Station

摘要

In this paper, the configuration of AC filter in Shaoshan converter station is analyzed in detail. Then, combined with the reactive power control function, the individual switching modes of the AC filter are compared and analyzed, simultaneously, an improved investment strategy for the average input of the filter is proposed, which reduces the impact and influence of the fault of AC filter busbar in the station on the AC system. The method proposed in this paper has certain reference significance for the design and operation of UHVDC transmission engineering.
