智能变电站过程层网络中开关量多设备共享应用方案研究

Application scheme of intelligent substation switch value multi-device sharing

介绍了智能变电站二次设备之间的过程层网络GOOSE报文交互的基本原则,分析了过程层网络中可能存在的启失灵开入、单双套配合、联闭锁信号等源与接收端之间的多设备共享关系。提出了多个GOOSE源对应于同一个接收设备、多个接收设备对应于同一个GOOSE源、多个二次设备之间GOOSE广泛共享等开关量共享方案。从失灵GOOSE开入共享、充电手合GOOSE开入共享、双套配置间相互闭锁重合闸、测控设备跨双网上送告警等方面阐释了多设备共享的实施方案。给出了此类多设备共享类GOOSE开入在接入二次设备之后基于辅助电气量回路的隔离原则。

This paper outlines the basic principles of process-layer network GOOSE message communication between intelligent substation secondary devices and analyzes possibte mufti-device sharing relationship between receiving terminal and sources such as start failure input, single/double protection configuration, block/tmblock signal, etc. The switch value sharing schemes of multi GOOSE source corresponding to one receiving equipment, multi-receiving equipement corresponding to one GOOSE source, GOOSE wide sharing among multi secondary equipments, etc~ are proposed. The implementation scheme of multi-device sharing is expounded in terms of failure GOOSE input sharing, charging hand-switch GOOSE input sharing, mutual blocking reclosure between double-set configuration, measurement and control equipment cross dual net up-sending warning, etc. The isolation principles based on auxiliary electrical circuit after such multi-sharing GOOSE input switching into secondary devices are given.
