描述
水位測(cè)控裝置是水電廠的重要測(cè)控設(shè)備,水電廠的上下游水位是防汛安全的重要數(shù)據(jù),攔污柵壓差影響機(jī)組出力、水工建筑安全,水頭值影響調(diào)速器協(xié)聯(lián)曲線,進(jìn)而影響機(jī)組效率甚至安全穩(wěn)定運(yùn)行,因此水位測(cè)控裝置需滿足長(zhǎng)期穩(wěn)定可靠運(yùn)行。目前的水電廠水位測(cè)控裝置普遍采用定制儀表采集前端水位傳感器的格雷碼值,換算柵差、水頭等,輸出開關(guān)信號(hào)報(bào)警,輸出出4~20ma信號(hào)至監(jiān)控、遠(yuǎn)動(dòng)、調(diào)速器。在運(yùn)行維護(hù)中存在以下問題:采用電纜長(zhǎng)距離輸送格雷碼信號(hào),防雷、抗干擾能力差,儀表、傳感器易損壞;4個(gè)24位格雷碼傳感器需100芯電纜維護(hù)困難;定制的儀表擴(kuò)展性差,輸入、輸出校準(zhǔn),參數(shù)整定操作復(fù)雜;價(jià)格高,備品備件采購困難。因此開發(fā)基于通用硬件設(shè)備的水位測(cè)控裝置意義重大。
根據(jù)水電廠水位測(cè)控具體要求,我們自主設(shè)計(jì)了基于PLC的水位測(cè)控系統(tǒng),具有高可靠性、配置靈活、安裝維護(hù)簡(jiǎn)單方便特點(diǎn)。
