【摘要】：目前火電廠普遍采用集中布置的水島系統(tǒng),以實(shí)現(xiàn)對各個(gè)用水系統(tǒng)的統(tǒng)一協(xié)調(diào)和智能化控制,減少運(yùn)行人員的檢修工作量。本文基于現(xiàn)場總線控制系統(tǒng)(FCS)及FDMS軟件,開發(fā)了智能水島控制系統(tǒng),該系統(tǒng)包括系統(tǒng)初始化、水網(wǎng)控制系統(tǒng)、數(shù)據(jù)分析系統(tǒng)、幫助運(yùn)維手冊4個(gè)模塊。通過對燃煤電廠各子系統(tǒng)給排水量監(jiān)測采集系統(tǒng)的數(shù)據(jù)進(jìn)行加工處理,在水量精準(zhǔn)計(jì)算的同時(shí)依托FCS大數(shù)據(jù)的分析,基于梯度用水原則,實(shí)現(xiàn)了燃煤電廠各用水子系統(tǒng)用水量的優(yōu)化;對各子系統(tǒng)受控設(shè)備進(jìn)行健康度分析,解決了水島控制系統(tǒng)中供水母管工藝產(chǎn)生的判斷啟動公用設(shè)備問題,并可以進(jìn)行設(shè)備故障預(yù)警及故障分析,實(shí)現(xiàn)了水島控制系統(tǒng)的全自動化。該智能水島控制系統(tǒng)應(yīng)用在某超超臨界機(jī)組中,控制效果良好,實(shí)現(xiàn)了火電機(jī)組用水系統(tǒng)節(jié)能降耗及故障預(yù)測。
[Abstract]:At present, the centralized water island system is widely used in thermal power plants to realize the unified coordination and intelligent control of each water system, and to reduce the overhauling workload of the operators. This paper is based on the fieldbus control system (FCS) and FDMS software. The intelligent water island control system is developed. The system includes system initialization, water network control system, data analysis system, Through processing and processing the data of each subsystem of coal-fired power plant for monitoring and collecting system of water displacement, relying on the analysis of FCS big data while accurate calculation of water quantity, based on the principle of gradient water use, The water consumption of each water subsystem in coal-fired power plant is optimized, the health degree of each subsystem controlled equipment is analyzed, and the problem of judging and starting public equipment produced by the water supply master pipe process in the water island control system is solved. The intelligent water island control system is applied in a super supercritical unit, and the control effect is good. The energy saving and consumption reduction and fault prediction of water use system of thermal power unit are realized.
