摘　　要：随着社会对供电可靠性要求的提升,配电网环网联络开关多处于热备用状态,在线路故障时能够快速复电。但在非故障和非人为操作的情况下,已发生多起联络开关异动合闸导致线路长期合环运行的事件,增加了设备运行和调度操作风险,严重影响了电网安全稳定运行。为了能够监测自动化及非自动化配电联络开关异动情况,快速纠正线路误合环问题,本文改进配电自动化主站环网联络识别方式,提出一种开关异动感知和自适应纠正算法,实现联络开关异动合环感知,定位最优解环点并程序化解环,通过测试验证该算法的可行性,有效避免线路长期合环带来的电网运行隐患及误操作风险,提升配电网动态防误技术及电网安全管控水平。With the improvement of social demand for the reliability of power supply,the distribution loop switches are mostly in hot standby state,which can improve the resumption efficiency quickly in case of line failure tripping.However,many misoperation incidents of loop switches leading to long-term loop closing operation happen in non-fault and non-manual operation circumstances,which increases the risk of equipment operation and dispatching operation,and also seriously affects the safe and stable operation of the power grid.To monitor the misoperation of automated distribution loop switches and non-automated distribution loop switches,correct the misoperation of loop closing in distribution network quickly,this paper improves the identification methods of the relation in network of the distribution automation system,and puts forward an algorithm about how to detect the loop switch misoperation and correct the misoperation adaptively.It achieves the detection of loop switch misoperation and locates the best point to unlock the loop closing network by distribution automation system.The feasibility of the algorithm is verified through tests,which can avoid the hidden danger and misoperation risk of power grid caused by long-term loop closing effectively,and promote the level of dynamic anti-misoperation technology and power grid security control.
