摘要
针对双重化智能站域保护在检修、故障退出、灾变恢复等多种场景下可靠性不充分的问题,提出远程备用智能保护一体化中心(Remote Duplicate Configuration Smart-Protection Center,RDCSPC)继电保护新架构,需研究RDCSPC的动作逻辑情况。根据其与双重化智能站域保护之间的配合关系,使用Hierarchical Petri net Simulator(Hi PS)软件分别建立RDCSPC在热备用、冷备用工作模式下的时序Petri网(PN)模型并对之进行动态仿真分析,同时,采用PN矩阵分析法对所建立的时序PN模型进行描述验证。模型验证结果表明:所建立的时序PN模型可以有效的描述RDCSPC的动作逻辑。
Aiming at the problems of dual-redundant smart substation area protection in terms of maintenance,failure exit,disaster recovery,and other scenarios where reliability is not sufficient,a new architecture of RDCSPC(remote duplicate configuration smart-protection integration center)for relay protection system is proposed in this paper,its action logic needs to be studied.According to the cooperative relationship between it with the dual-redundant intelligent substation area protection,Hi PS(hierarchical Petri net simulator)software is used to establish the PN(Petri net)model of the RDCSPC in spinning reserve and cold stand-by modes and perform dynamic simulation.Meanwhile,the PN matrix analysis method is used to describe and verify the time-sequence established PN model.The model verification results show that the time-sequence established PN model can effectively describe the action logic of RDCSPC.
