Abstract:

架空线-电缆混联输电线路发生故障时,单端故障行波难以辨识,无法直接用以定位故障点。为提升单端量测距的实用性,提出一种基于故障距离区间的混联输电线路单端行波故障测距方法。首先,利用基于单端工频量的逐段推演故障区段法,初步划定故障距离区间,并通过在线估算对端等值阻抗以确保所划定的区间的正确性;然后,分析划定的区间内的行波传播规律,构建故障点精确定位方法,针对区段连接点邻域内故障的特殊场景,提出连接点故障识别判据和故障区段判据;最后,通过剔除待辨识波头所在区间内的干扰波确保算法精度和可靠性。仿真结果表明,该方法测距精度高,不存在区段连接点邻域测距死区,通用于多段混联输电线路,具备较高的实用价值。
