摘要
针对某区域内6 kV配电网现阶段存在的线路及负荷保护无级差配置、故障停电范围大及越级跳闸等问题,提出通过基础设施及自动化设备更新,并对系统等效阻抗及短路电流计算,设置符合标准的继电保护整定值,以提升区域内配电网故障切除的自动化能力。
In response to the existing problems of line and load protection without stage difference configuration,large fault outage range and overstep tripping in a regional 6kV distribution network,the update of the infrastructure and automation equipment is proposed,the equivalent impedance and short-circuit current of the system is calculated,the standard relay protection setting value is set,so as to improve the automation capability of fault removal in the regional distribution network.
