本文针对重载牵引系统列车运行的负荷特点,提出在馈线微机距离保护中实现谐波闭锁、防止保护误动的原理与两种算法,经上机模拟试验表明对于完善距离保护功能、提高其动作选择性都有明显的效果。
In this paper, based on the load characteristics of heavy haul trains running on trains, this paper proposes the principle and two algorithms to realize harmonic lockout and protection against maloperation in feeder distance protection. The simulation results show that for improving the distance protection function and improving the operation Selectivity has obvious effect.
