摘要
为了建设全过程模块化的智能变电站,实时地监测继电保护装置,提出了一种智能变电站虚回路的在线状态监测技术。在智能变电站全过程模块化管控策略的基础上,研究了SCD文件的图形化展示技术,提供了装置自身运行状态、软压板投运状态、逻辑链路状态等综合信息。同时在线状态监测系统中将熵权法和灰色关联分析法相结合,用于综合评价识别智能变电站虚回路中的故障类型,及时消除故障隐患,提高现场运维人员的工作效率,进而推进变电站智能化的发展。
In order to construct a modular intelligent substation and monitor the relay protection device in real time, an online state monitoring technology for the virtual circuit of intelligent substation is proposed. Based on the whole process modularized control strategy of smart substation, this paper studies the graphical display technology of SCD files and provides integrated information such as the operating status of the device itself, the operation state of the soft press plate and the state of the logic link. In on-line condition monitoring system, entropy weight method and Grey Relational Analysis(GKA) are combined to comprehensively evaluate the fault types in the virtual circuit of intelligent substation, eliminate the problems in time, improve the work efficiency of field operations staff, and promote the development of intelligent substation.
