Design And Implementation Of Distributed Monitoring And Control System For Campus Thermodynamic Network

With the rapid economic development, the campus building heating demand in thecontinuing growth of the heat supply capacity is also expanding. How effectivesupervision and control of the operation of the heating network, how to improve theheating quality, and improve the quality of heating at the same time, reduce the energyconsumption of the campus thermal network urgent problems.Based on the importance and special nature of the campus heating network，Climate Compensatorand， Building Spot controller and other equipment was designedin the project. Climate Compensatorand control network, Building Spot controllercontrol the secondary network, the monitoring center to monitor the adjustment of theoperating parameters. The purpose of the heating network as an organic wholeregulatory control. The main research work is divided into the following aspects:1.Through the analysis of working principle of the Climate Compensatorand,electric three-way valve, installed the Climate Compensatorand and electric three-wayvalve in the campus heating network. Charting the data obtained from experimentallymeasured data applications, performance analysis, the conclusion derived ClimateCompensatorand with the outside temperature changes can be automated climatecompensation. Ensure the heating quality, to achieve energy savings.2. Through the analysis of working principle of Building Spot controlle, installedin the entrance to the building heat pipe network Building Spot controlle and electricthree-way valve. The application of experimental data charting, analysis of buildingtime-sharing temperature controller of the energy-saving, time-sharing sub-temperatureperformance. And analysis of the thermal process system is running mechanism andinfluencing factors for the nonlinear, large delay, strong coupling characteristics of the pipe network heat balance control algorithm, the application of neural networks withincomplete derivative PID control algorithm combining the system simulation3. Based on heat exchanger station SCADA system (Kunlun6.0configurationsoftware), Ethernet communication, the Climate Compensatorand, Building Spotcontroller points the temperature controller and a monitoring center. Various functionsof the application configuration system makes co-ordination, management center in realtime scanning equipment condition and operating parameters for each monitoring point,by the way of the graphic collection the heating situation at the sence.
