摘要
分析了一般常用定检方法在实际应用中存在的问题,提出了一种500kV线路保护定检简便方法。结合500kV线路保护定检的要求,具体分析了该500kV线路保护定检简便方法的试验接线策略和自动测试模板及其功能实现。实际应用结果表明,所提出的保护定检简便方法可有效缩短定检时间,减少人为误操作,提高定检效率,实现500kV线路保护定检简便化,具有一定的实际推广价值。
The problem of the traditional periodic inspection method for 500 kV transmission line protection devices is analyzed, and a new simplified periodical inspection method is introduced .C ombined with the traditional periodic inspection demand for 500 kV transmission line protection devices, t he working principle and automatic test strategies are discussed, as well as the function application. Application in the practical power system shows that the simplified approach is valuable to be widely popularized for reducing the inadvertent mal-operation and improving the efficiency of periodical inspection.
