現地級機組LCU的功能
2.1 數據采集及處理
1) 開關量采集及處理
狀態開關量的采集及處理：機組LCU按周期掃查全部開入量，進行狀態檢查，更新數據庫，在開關量發生變位時，可以產生事件記錄，并根據控制流程進行動作處理或接點復歸處理。處理內容事先由設計人員根據機組的運行要求編寫在控制流程之中。當事故類信號變位時，LCU根據流程控制機組進行事故停機。如屬于故障類信號變位時，LCU則進行登錄和報警處理。所有事件記錄，流程的執行情況不僅保存于機組LCU，還全部送廠級監控層。在狀態開關量中，有一種綜合開關量，這實際是一種若干個開入量按一定邏輯關系得到的一個中間變量，此量可供-LCU或裝置使用，如機組空載狀態，機組發電狀態等即屬于這一類，往往以開出的方式引出，或僅作為LCU本身內部的一個宏變量供流程使用。機組LCU狀態開關量共有90多個，這些量包括：斷路器的開/合，導葉的位置，油位的高低，油泵的啟、停等。
中斷開關量的采集與處理：中斷開關量具有中斷能力，響應速度快（<10ms），可按其變位發生時間的先后形成事件順序記錄。水輪機、發電機、瓦溫過高、壓力油泵、過速信號、機組的勵磁、保護等事故信號作為中斷開關量輸入，共20多點。機組LCU一旦收到這些表明機組發生事故的信號，會立即中斷當前的工作，快速轉到事故流程進行處理。并按要求形成事件順序記錄。
