摘要
通过深入分析金新化工总降110 kV母线差动保护装置的保护原理及功能配置,总结出适合于该保护的模拟校验方法,并进行了优化。对差动保护功能进行了完善,对闭锁110 kV备自投的设置进行了修正,通过实际验证,消除了影响电力系统安全、稳定运行的潜在隐患。
Through an in-depth analysis of the protection principle and functional configuration of the 110 kV bus differential protection device of main substation in Jinxin Chemical company,the simulation verification method suitable for the protection is summarized and further optimized.The differential protection function is improved,and the setting for blocking the 110 kV backup power automatic switching is corrected.The potential hazard affecting the safe and stable operation of the power system is eliminated through actual verification.
