银东直流输电工程站用电系统典型设计分析及改进

摘要

By analyzing the typical defects in the auxiliary power system of the Yinchuan-Qingdao ±660 kV DC Transmission Project construction process, and summarizing the improved measures taken on site, we raise that the reliability of auxiliary power system in any operation mode should be taken into full consideration during its design stage to avoid the block of HVDC system because of auxiliary power system faults, and provide advices on the auxiliary power system design of new converter station.%通过对银东直流输电工程站用电系统建设过程中的典型缺陷进行分析，总结现场已采取的改进措施，提出直流T程设计时应充分考虑站用电系统在各种运行方式下的运行可靠性，避免因站用电系统故障导致直流系统停运，并为新建换流站的站用电系统设计提出建议。
