摘　　要：在介绍换流站低压直流系统的组成、作用以及重要性的基础上,对上海南桥换流站2013年低压110V直流系统改造做了简单回顾。叙述了改造前南桥换流站低压直流系统的运行状况、控制策略以及存在问题,从站内运行维护角度出发,对低压直流系统改造方案进行了补充和完善。特别是通过比对新老系统在直流接地故障上的不同排查方法,证实了老站实施低压直流系统改造的可行性和必要性。On the base of the structure, function and importance of the low voltage DC system to the convertor station, this paper gives a brief review on the reconstruction programme of the low voltage 110 V DC system to Shanghai Nanqiao convertor station, in 2013. Firstly, it describes the operating condition, control strategy and the existing problems of the low voltage DC system on Nanqiao convertor station before the reconstruction pro- ject. FurthermOre, from the perspective of operation and maintenance to the convertor station, the reconstruction proposal of the low voltage DC system is supplymented and improved. Especially, through the different testing methods on the DC system grounding fault by comparison with the new and the old system, it demonstrates the feasibility and necessity of the reconstarction programme on the old low voltage DC system to this convertor station.
