APPLICATION AND EFFECT ANALYSIS OF HEATING SYSTEM BASED ON TRI-NETWORK JOINT REGULATION AND CONTROL TECHNOLOGY

ABSTRACT
In recent years, the state promotes intelligent heating and clean heating, which aims to achieve energy saving, emission reduction, cost reduction and efficiency, and improve the social and economic benefits of heating enterprises on the premise of ensuring the heat demand of the terminal heat users of the heating system. This paper first introduces the current situation of the heating system, analyzes the main problems and causes of the current heating system, and then analyzes the practical application and operation data of the three-network joint control technology of the heating system independently developed by Jilin Yuheng Industrial Electric Co., Ltd in Changchun Lianhuashan Thermal Power Co., Ltd., and finally comes to the conclusion that the application of this technology makes the heating system energy-saving effect is remarkable. It can adapt to all kinds of complex heating systems and has good market prospect and application value.
