摘  要：基于供水系統(tǒng)SCADA數(shù)據(jù)構(gòu)建水廠變流變壓曲線(xiàn)模型，曲線(xiàn)任意點(diǎn)的出廠壓力隨出廠流量的變化而調(diào)節(jié)并推斷末端壓力恒定，桂城水廠應(yīng)用高壓變頻器控制泵群沿此曲線(xiàn)運(yùn)行調(diào)節(jié)流量與壓力，滿(mǎn)足用戶(hù)需求且沒(méi)有多余揚(yáng)程，千噸水電耗降低了7.62～10%，管網(wǎng)末端服務(wù)壓力精度±0.002MPa。 關(guān)鍵詞：高壓變頻器；水泵；變流變壓曲線(xiàn)； Abstract: Construct a water variable flow and pressure curve model for water supply SCADA system data based on, curve at any point of the factory pressure adjusted with the changes i[登陸后可查看全文]
