DR-100-24
水東水電站裝設(shè)有上游、#1攔污柵后、#2攔污柵后、下游四個(gè)水位測量井,配置浮子式水位測量裝置,采用絕對值光電編碼器將水位信息轉(zhuǎn)換成數(shù)字信號(hào)。壩上傳感器距離中控室500m,下游傳感器距離中控室30m,為提高系統(tǒng)的防雷、抗干擾能力,壩上傳感器通信采用光纖傳輸。水位測控裝置plc通過rs485串行口采集編碼器水位數(shù)據(jù),經(jīng)過換算處理模擬量輸出模塊輸出4~20ma的上游、下游海拔值信號(hào)至遠(yuǎn)動(dòng)rtu裝置,輸出4~20ma的水頭信號(hào)至機(jī)組調(diào)速器電氣調(diào)節(jié)裝置
絕對值編碼器由機(jī)械位置確定編碼,每個(gè)編碼唯一不重復(fù),它不受停電、干擾的影響,無需記憶,無需找參考點(diǎn),而且不用一直計(jì)數(shù),什么時(shí)候需要知道位置,什么時(shí)候就去讀取,這樣,編碼器的抗干擾特性、數(shù)據(jù)的可靠性大大提高了。多圈絕對值編碼器另一個(gè)優(yōu)點(diǎn)是由于測量范圍大,實(shí)際使用往往富余較多,這樣在安裝調(diào)試時(shí)不必費(fèi)勁找零點(diǎn),將在測量范圍內(nèi)的某一中間位置作為起始點(diǎn)就可以了,從而大大簡化了安裝調(diào)試難度。
