摘要
站用电系统的安全可靠对换流站及电网安全运行的影响举足轻重,针对换流站站用电系统的较高可靠性要求,提出站用电系统的设计原则,结合工程实践提出站用电系统的典型接线。控制保护系统是站用电故障及异常情况下可靠运行的重要保障,对控制保护特别是站用电系统中的备自投等展开系统分析,提出工程实施方案。
The reliability of auxiliary power system plays a considerable role in grid operation. Considering the demand for high reliability of auxiliary power system, this article proposes the design principle and typical connection model. When fault or abnormity occurs, control and protect system ensure secure operation of auxiliary power system, so automatic switching of auxiliary power system is analyzed. The detailed retrofit scheme proposed for design of auxiliary power system is a great help to the design.
