摘要
变电站的正常运行保证了供电的可靠性,如果变电站中的某个部分出现故障,就会导致停电的情况发生,将会对人民的生活带来很大的影响,因此对变电站的故障分析非常重要。某220 kV变电站出现110 kV线路断路器跳闸,通过对线路的保护装置动作排查,以故障线路录波情况为主线进行分析,得出线路跳闸的准确原因。此分析结果对同类型线路的安全稳定性以及供电可靠性的提高具有实质性的指导意义,有助于减少大面积停电造成的巨大经济损失。
The normal operation of the substation ensures the reliability of the power supply.If a certain part of the substation fails,it will lead to a power outage,which will have a great impact on people′s lives.Therefore,fault analysis of substations is very important.A 110 kV line circuit breaker tripped at a 220 kV substation.Through the operation of the protection device of the line,the fault line recording situation is analyzed as the main line,and the accurate cause of the line trip is obtained.This analysis result has substantial guiding significance for the safety and stability of the same type of line and the improvement of power supply reliability,which is helpful to reduce the huge economic loss caused by large-scale power outage.
