闭锁备自投回路实用化分析与研究

Analysis and Research on Practicality of Locking Spare Power Switchover Unit Loop

论述某扩大内桥接线变电站220kV备自投设计中存在的问题,提出了相应的整改措施,并比较了闭锁备自投两种实现方法的优劣。在对比分析基础上,结合不同变电站的实际需求,提出了备自投设计实用化建议。

This paper discussed the problems existing in the design of 220kV spare power switchover unit design of an expanded inner bridge connection substation,proposed corresponding rectification measures,and compared two methods′advantages and disadvantages of spare power switchover unit.On the basis of comparative analysis,this paper put forward a practical proposal for the spare power switchover unit in combination with the actual needs of different substations.
