一起变电站10kV馈线线路跳闸典型事故分析及处理

Andlysis and Handling of a Typical Accident of 10kV Feederline Trip of a Subtation

10kV馈线线路运行的安全性、可靠性和稳定性直接影响着变电质量,是新时期变电站运维管理的重中之重。本研究从一起变电站10kV馈线线路事故出发,根据保护动作时序、调度处理过程等分析其跳闸致因及可能造成的后果,并提出处理方案,调整馈线开关和线路开关适配,望在一定程度上改善变电站10kV馈线线路的可靠性能。

The stady starts with line auident of 10 kV feeder Line of a substation, analyse its leading to the consequence because of trip and nuts forward handling and adjusts adaptation between the feeder switch and line switch, which hopes to improve reliability of 10 kV feeder line of the substation in a degree.
