摘要
通过对输电线路短路故障分析及计算,所设置的保护能够根据系统的运行方式,距离故障点的远近,故障的种类,自动地、自适应地进行工作,同时保证了动作的选择性,提高了保护的灵敏度.实现了输电线路短路故障的自适应保护.
By the analysis and calculation for short circuit of power lines,the protection can assume automatically the adaptive reaction and operation according to the system mode,the distance between the fault point and the protection and the variety of fault.Simultaneously,the selectivity is ensured and the sensitive is improved.As a result,the adaptive protection for the short circuit of power lines is realized.
