摘　　要：在分析电压自适应和相位自适应重合闸判据的基础上,结合同杆并架双回线单相故障和单相跨单相故障时的电气量特征,提出了一种基于相位自适应判据、电压自适应判据及按相序重合的组合判据。仿真结果表明该判据可以准确地判别同杆并架双回线路单相故障和单相跨单相故障的故障性质,有助于提高同杆并架双回线路自动重合闸的成功率,降低重合于永久性故障时对电网安全稳定运行的影响。This paper deeply analyzes the voltage adaptive reclosure and the phase adaptive reclosure,and then presents a new adaptive reclosure basing on the characteristics of single phase fault and single phase cross single phase fault in double transmission lines on the same tower.Digital simulation indicates that the new adaptive reclosure can judge the fault properties of single phase fault and single phase cross single phase fault in double transmission lines on the same tower exactly.
