VFS7-2075UPL系統(tǒng)間隔層主要由保護(hù)單元和測控單元組成，每個(gè)測控單元監(jiān)控多路饋進(jìn)饋出，采用先進(jìn)現(xiàn)場總線CAN，現(xiàn)場通信采用雙絞線，總線速率達(dá)1 Mbps，快速、可靠、方便靈活，通信規(guī)約支持IEC-60870-5-101格式，克服RS485網(wǎng)絡(luò)上只能有一個(gè)主節(jié)點(diǎn)而無法構(gòu)成多冗余系統(tǒng)的缺陷，具有很高的價(jià)格比。另外，采用雙CAN現(xiàn)場總線內(nèi)部定期對備用CAN進(jìn)行備用檢測，提高了內(nèi)部網(wǎng)絡(luò)的冗余度。

站控層采用雙10 Mbps雙絞線以太網(wǎng)結(jié)構(gòu)（能保證變電站自動(dòng)化系統(tǒng)內(nèi)部通信網(wǎng)絡(luò)傳輸?shù)膶?shí)時(shí)性），由雙服務(wù)器組成，站控層為值班人員提供全廠系統(tǒng)的監(jiān)視、控制和管理功能，界面友好，容易使用。通過組件技術(shù)，軟件功能能實(shí)現(xiàn)“即插即用”，能較好地滿足電氣監(jiān)控系統(tǒng)的需要，軟件系統(tǒng)采用模塊化結(jié)構(gòu)，開放性較好。站控層操作系統(tǒng)可采用Windows2000/NT，數(shù)據(jù)庫選用SQL服務(wù)器，軟件主要功能模塊有前置、數(shù)據(jù)庫生成器、數(shù)據(jù)庫組態(tài)、報(bào)表管理、報(bào)警信息、曲線、棒圖、動(dòng)作告警、SOE、事故追憶、錄波分析、人機(jī)界面、自動(dòng)抄表、設(shè)備管理、定值管理、設(shè)備在線診斷、系統(tǒng)組態(tài)等。電氣監(jiān)控系統(tǒng)中提供了故障信息傳輸系統(tǒng)、各級調(diào)度中心、電能計(jì)量系統(tǒng)、直流系統(tǒng)通信等接口驅(qū)動(dòng)軟件。
