| 摘 要： | 母线保护中的充电保护,主要是在充电操作时投入,快速跳开母联,切除故障,保全非故障段母线。在高中压系统,充电保护电流定值是按躲过最小运行方式故障电流整定,并要求瞬时动作;通过大量试验证明:充电保护的动作精度和快速性很难达到统一。经过详细的分析,在保证母线保护功能前提下,可以取消微机母线保护中的充电保护,从而简化保护。

| Abstract: | The charge-protection in bus-bar protection is applied before charge-operation.It can break bus-tie switch and detach the fault rapidly for saving the sanity bus-bar.In high-middle voltage power system,the current setting of the charge-protection always bases on the fault current in the minimal operation mode,and the break should be snapped action.Through a lot of trials,the paper proves that it is difficult to be harmonious for the accuracy and rapidity of charge-protection's response.Through detailed analysis,on the premise of ensuring the bus-bar protection's function,the paper advises that the charge-protection could be abolished to simplify protection. |
