【摘要】：目前火电厂普遍采用集中布置的水岛系统,以实现对各个用水系统的统一协调和智能化控制,减少运行人员的检修工作量。本文基于现场总线控制系统(FCS)及FDMS软件,开发了智能水岛控制系统,该系统包括系统初始化、水网控制系统、数据分析系统、帮助运维手册4个模块。通过对燃煤电厂各子系统给排水量监测采集系统的数据进行加工处理,在水量精准计算的同时依托FCS大数据的分析,基于梯度用水原则,实现了燃煤电厂各用水子系统用水量的优化;对各子系统受控设备进行健康度分析,解决了水岛控制系统中供水母管工艺产生的判断启动公用设备问题,并可以进行设备故障预警及故障分析,实现了水岛控制系统的全自动化。该智能水岛控制系统应用在某超超临界机组中,控制效果良好,实现了火电机组用水系统节能降耗及故障预测。
[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.
