A thermal power plant water balance monitoring system

Abstract

The invention discloses a water balance monitoring system for a thermal power plant. A meter position of a three-level water balance meter for the thermal power plant is designed, monitoring meters can be reduced as much as possible under the premise that a water system is fully monitored. The real-time data monitoring, analysis and prediction of all the water consumption units and the systems ofthe power plant are realized. Favorable conditions are provided for safe and stable operation of the water system, and the operation management level of the water system is improved. The water resource allocation of the whole plant is tracked and optimized in real time according to the real-time water balance result, and comprehensive planning and comprehensive balance of water supply, water consumption, and water drainage of the whole plant can be realized, so that the water resources can be reasonably and fully utilized in the production and daily life of the power plant. Multi-purpose and stepped use of water can be achieved. The water repeated utilization rate is increased, water consumption indexes of the whole plant can be reduced, the sewage discharge can be reduced, and the purposeof zero emission can even be achieved.

Description

technical field [0001] The invention relates to the technical field of water supply systems and water systems, in particular to a water balance monitoring system for thermal power plants. Background technique [0002] Three-level water volume balance refers to the water volume balance of water units, water subsystems and the water system of the whole plant, the total input water volume and total output water volume of each water use unit and water system. At present, the entire water management system of most power plants has problems such as scattered monitoring information, no unified storage, processing and application, and a low degree of water informationization. It is impossible to quickly locate the leakage of key water systems and diagnose and prevent equipment failures. The installation rate of secondary and tertiary water meters in most power plants is relatively low, and the phenomenon of "running, emitting, dripping and leaking" in the water supply pipe network o...

Problems solved by technology

At present, the entire water management system of most power plants has problems such as scattered monitoring information, no unified storage, processing and application, and a low degree of water informationization. It is impossible to quickly locate key water system leakage and prevent equipment failures.

The installation rate of secondary and tertiary water meters in most power plants is relatively low, and the phenomenon of "running, emitting, dripping and leaking" in the water supply pipe network occurs from time to time and cannot be quickly located and checked. In addition to relatively complete metering equipment, the ratio of metering instruments for water and drainage in other systems is relatively low
