配電室作為智能建筑系統(tǒng)的電力中心，向整棟大樓提供照明、消防、公用設備及辦公設備的用電。智能型電力儀表就是可以對整個供電網(wǎng)絡進行測量，分析及顯示的儀器。由于智能建筑的供電網(wǎng)絡很龐大，所以使用的智能型電力儀表數(shù)量也比較多。這就需要一套可靠的監(jiān)控系統(tǒng)與所有的智能儀表進行數(shù)據(jù)交換，實現(xiàn)對整個配電網(wǎng)絡進行監(jiān)控，從而實現(xiàn)電力的故障報警和優(yōu)化管理。
使用和利時LK系列和LM系列PLC的電量采集系統(tǒng)因其可靠性高、自由通訊數(shù)據(jù)通訊量大、通訊編程靈活而得到采用。
電量采集系統(tǒng)實現(xiàn)了對電力儀表中各個數(shù)據(jù)的采集功能，數(shù)據(jù)包括頻率、相電壓、線電壓、相(線)電流、有功/無功/視在功率、功率因數(shù)、絕對有功電度和絕對無功電度等。其中LM系列PLC使用自由口通訊與所有的智能電力儀表進行通訊，并實現(xiàn)對儀表數(shù)據(jù)的儲存和上傳。LK系列PLC完成對所有LM系列PLC中儀表數(shù)據(jù)的統(tǒng)計和匯總，最后通過以太網(wǎng)將數(shù)據(jù)傳送到上位監(jiān)控計算機，實現(xiàn)對全部供電系統(tǒng)狀態(tài)的監(jiān)視。
系統(tǒng)設計
電力采集系統(tǒng)一般由以LK和LM系列PLC為核心的通訊機柜組成。系統(tǒng)裝置如圖2-1所示。電力監(jiān)控柜里配置有1套LK系列PLC，10套LM系列PLC及電源。每套LM系列PLC均有一個RS485接口和一個PROFIBUS-DP接口，其通過RS485串口與智能儀表進行通訊，再通過PROFIBUS-DP總線將讀上來的儀表數(shù)據(jù)傳送到LK系列PLC中。LK系列PLC通過以太網(wǎng)通訊將匯總的配電室內(nèi)的所有數(shù)據(jù)傳送到上位監(jiān)控計算機。
由于需要采集的儀表數(shù)量很多，且每塊儀表讀取的數(shù)據(jù)量大，所以采用多套LM系列PLC與儀表連接進行數(shù)據(jù)采集。LM系列PLC的RS232和RS485串口具有自由口通訊功能，可以針對儀表支持的協(xié)議自由進行編程，參數(shù)的設定和更改都很方便，在此針對儀表支持的MODBUS RTU協(xié)議進行主站編程。LK系列PLC擁有16M的數(shù)據(jù)存儲空間，支持PROFIBUS-DP和以太網(wǎng)(MODBUS TCP)通訊，可以方便的與LM系列PLC和上位計算機進行連接。使用LK系列PLC匯總LM系列PLC讀取的數(shù)據(jù)大大優(yōu)化了網(wǎng)絡結構。
