摘　　要：针对电气化铁路供电臂易发生故障且难以及时恢复的问题,提出了供电臂自愈重构方法。该方法基于现有的牵引变电广域保护系统,将变电所站域保护测控装置设为自愈重构主装置,通过建立与故障类型、故障区段相对应的自愈重构流程,利用广域保护系统的广域通道及过程层通道,实现主装置与其他装置之间的信息交互,完成自愈重构功能。通过现场试验验证了该方法的有效性与正确性。With regard to the problem of frequent occurrence of failures of feeding section on electrified railway which are difficult to recover,the paper puts forward a method for self-healing and reconfiguration for the feeding section.With support of existed wide area protection system for traction substation,the method is able to realize the information exchange between main equipment and other equipment and accomplish the self-healing reconfiguration function,by setting the station domain protection and control equipment to be the self-healing reconfiguration equipment,establishing of self-healing reconfiguration flow corresponding to the type of failure and failed section,and by application of wide area channel and process layer channel.The effectiveness and correctness of the method have been verified by tests executed at site.
