摘　　要：分析了目前同杆双回输电线路的主要保护,分别对基于工频量和暂态量的双回线路保护研究内容进行了综述。介绍了双回线路保护基于工频量的故障分析、故障识别和故障选相,基于暂态量的故障电气行波分析和故障识别,在此基础上分析了现阶段同杆双回线路保护的特点和实际运行中出现的问题,讨论了今后的研究思路,并对其发展方向进行了展望。Main protection of double-circuit transmission lines at present was analyzed. The protection based on power frequency and transient quantity were reviewed respectively. The fault analysis, fault identification, fault phase selection of the protection based on power frequency, and the fault electric traveling wave analysis and fault identification of protection based on transient quantity are introduced. Based on the introduction, the characteristics and the problems in actual operation of the protection are analyzed. The development trend was discussed and the prospect in the future was analyzed.
