新一代智能变电站保信子站设计模式探讨

Discussion on Design Mode of Relay Protection and Fault Information Management Substation for a New Generation of Smart Substation

随着智能电网建设的快速发展,变电站内独立配置的保信子站功能集成到站控层的一体化监控系统中。本文基于新一代智能变电站的站控层设备配置提出了新一代智能变电站中保信子站功能模块常用的3种部署及实现模式,详细分析了3种模式的实现机制、信息流向及每种模式的优缺点。主要分析介绍了综合应用服务器、数据服务器、数据通信网关机协同工作模式,该模式充分利用了新一代智能变电站站控层设备资源,实现了站控层信息的统一存储、统一管理,充分体现了监控系统的一体化协同工作的特点。

With the rapid developing of smart grid construc tion, independent relay protection and fault information management sub station is gradually integrated into monito ring and control system at station control level. In this pa per, three common deployment and realization modes of re lay protection and fault information management sub station for a new generation of smart substation are proposed based on station level equipment of a new generation of smart substation. At the same time, the realization mechanism and information flow of three deployment and the advantages and disadvantages of each mode are analyzed in detail. In this paper, collaborative work mode of comprehensive ap plication server, data server and data communication gate way are introduced mainly. This collaborative work mode takes full advantage of station level equipment resources in the new generation of smart substation, which realizes the unified＇storage and management of station control level in formation, and fully reflects the collaborative work charac teristics of integrated monitoring system.
