摘要
在配网自动化系统中,小电流接地故障较为常见,对电网运行将会产生严重的负面影响。在配电自动化系统运行过程中,故障定位功能至关重要,能确保系统稳定运行。通过故障定位,能对故障发生范围进行控制,促使故障处理效率有效提升。但是当前配网自动化系统线路故障存在较多不稳定性特征,导致故障难以定位。所以,管理部门以及技术人员要强化电流故障判断,便于电网能够稳定运行。
In the distribution network automation system,small current grounding fault is common,will have a serious negative impact on the operation of the power grid.In the operation of distribution automation system,fault location function is very important to ensure the stable operation of the system.By fault location,the scope of fault occurrence can be controlled and the fault handling efficiency can be effectively improved.However,the current distribution network automation system line fault has many characteristics of instability,leading to the fault is difficult to locate.Therefore,management departments and technical personnel should strengthen the current fault judgment,so as to facilitate the stable operation of the power grid.
