Abstract:Aiming at the key scientific and technological problems of thermal power plant, such as large water consumption, high energy consumption, low water reuse rate and low intelligence level, a research method of key technologies and information platform construction of smart water in thermal power plants were proposed in this paper based on the research results of smart water. According to the status quo and situation faced by thermal power plant water informationization, the overall and specific objectives of the research are established.Combining on-site monitoring data and intelligent analysis theory and methods, the intelligent calculation method of water balance was put forward, the fault diagnosis and life prediction intelligent method of main equipment for thermal power plant wastewater treatment were established, and the historical and real-time cost estimation model of thermal power plant water treatment system was constructed. The network architecture, architecture and logical architecture design scheme of the information platform are proposed. The information platform integrated the auxiliary decision-making system of the water management of the thermal power plant, the key equipment of the thermal power plant system operation and the reliability analysis and evaluation model of the structure. This may provide a technical support for achieving water management of intelligent thermal power plants integrating water-saving, energy-saving, environmentally friendly, safe and economical.
