Remote Intelligent Monitoring Strategy of Heat-Supply Network Based on Kingview

To deal with control difficulties of coupling, nonlinearity and hysteresis in a centralized heat supply system of a heat-supply network, a remote monitoring system of heat-supply network based on Kingview is designed. It combines the concepts of energy conservation and environmental protection. Advanced control strategies are developed based on Kingview and a local PLC to realize site collection of district heating system parameters such as temperature, pressure, flow and valve opening. Thus accuracy of the heating control and quality of heating are improved. It is possible to achieve a good running condition of thermal water conservancy via fuzzy-PID control, temperature compensation control, thermal load budget, wireless remote, and other techniques. An optimization objective function and a nonlinear programming algorithm are established, and optimal operation solutions obtained with heating network parameters that can improve energy efficiency and system stability. Operation of a whole year shows that the design enhances the system's intelligent control, and has excellent energy efficiency. It is significant in adjusting quality, improving energy efficiency, and raising operation and management standards of urban central heating systems.
