摘要
主要阐述了高压直流输电换流站用交流滤波电容器组的关键技术,根据滤波需求及无功容量需求,计算得到滤波器电容器组的参数;根据绝缘配合、电场分布、及结构抗震等计算结果,得到电容器组单元参数及电容器组布置方案;并根据电容器组结构,提出滤波器组的不平衡保护方案。并以富宁换流站的交流滤波器电容器为例,验证了设计的合理性。目前,富宁换流站交流滤波器电容器组已投入运行,滤波及无功补偿效果良好。
Key technology on AC filter capacitor bank in HVDC converter station is mainly described in this paper and the parameters of filter capacitor bank is obtained by calculation in accordance with the need of filtering and reactive power capacity. The parameters and layout scheme of the capacitor bank are obtained as per the calculation result of insulation coordination, electric field distribution and structure seismic. The unbalance protection scheme is proposed according to the structure of the capacitor bank .The AC filter capacitor at Funing converter station is taken as an example to verify the design reasonability.At present, the AC filter capacitor bank of Funing converter station has been put into operation with good filtering and compensation result.
