摘　　要：500kV桂林变电站的间隔层、变电站层全部遵循IEC61850标准统一建模。500 kV桂林变电站采用PS6000+变电站自动化系统,通过IEC61850通信协议实现变电站层对间隔层数据的监视和控制。该工程除了直流屏等少数不具备网络通信能力的装置外,整个系统取消了规约转换器,各智能设备间完全采用IEC61850规约通信;远动通信服务器对间隔层IEC61850通信使用双网热备用模式,而后台监控则实现了双网双工;各测控装置的间隔层联闭锁则基于GOOSE组播数据共享而实现。Both station and bay levels of 500 kV Guilin substation are modeled according to IEC61850 standard. Its PS 6000^＋ substation automation system adopts IEC61850 protocol to implement the supervision of bay level data. Except a few devices without network communication ability,all IEDs directly communicate with each other according to IEC61850,without any protocol converter. Dual-network hot-backup mode is used in IEC61850 communication between telecontrol communication server and bay unit,while dual-network duplex mode is used in background monitoring. Bay level interlock among measuring and control devices is based on data sharing by GOOSE multicasting.
