牵引变电所备自投功能应用探讨与分析

Discussion and Analysis of Application of Backup Switching Functions of Traction Substation

结合近几年管内牵引变电所综合自动化系统备自投功能应用实际情况,针对因进线失压、主变故障或两种故障同时存在的情况下如何有效完成所内自投功能,分析存在的问题及原因,为综合自动化系统备自投逻辑功能完善及日常备自投故障分析提供参考。

Combining with the actual application status of backup switching function of automation system of traction substation under the jurisdiction,with regard to that how to effectively accomplish the automatic switching function in the station in the event of loss of voltage of incoming line,main transformer failure,or two types of faults existed simultaneously,the existed problems and the causes are analyzed,providing reference for improving of backup logic function and analyzing of daily faults of backup switching function of automation system.
