摘要
纵差保护在电力系统中应用非常广泛且特别重要 ,因此保证纵差保护接线的正确 ,是电力系统稳定运行的关键所在。由于受电力系统运行方式的影响 ,不可能使设备长时间停运检查 ,所以利用“极性法”快速判断纵差保护接线正确性 ,对保护投运。
Longitudinal differential protection is very important and is widely used in electric power system, and the wiring correctness of the protection is very important for electrical power system to operate stably. Off_line maintenance on the equipment is not allowed by the operating mode of electrical power system. Therefore, it is an effective way for the protection operation and event investigation by using “polarity principle” to identify wiring correctness of the longitudinal differential protection.
