Abstract

The invention discloses a heating adjusting and controlling method and system. The method comprises the following steps that a hydraulic and thermal coupled equation is built in a preset heat-supply network topology model according to preset heating parameters, wherein the heating parameters comprise heating parameters of a heating station, heating parameters of all users, parameters of a heat-supply network, parameters of a heat insulation layer, physical property parameters of a heating medium, climatic information and geographic position; temperature loss and hydraulic loss in the heating process are calculated according to the coupled equation, energy consumption is analyzed, and a first heating allocation scheme is obtained according to an optimization method; and the first heating allocation scheme is sent to the heating station so as to guide staff to adjust and control heating. The problems that hydraulic distribution is not reasonable and heat is imbalanced in the heating process are solved, and the heating reliability and effective use rate of energy are improved.

Description

Technical field [0001] The invention relates to the field of communication technology and heat supply control, and in particular to a heat supply control method and system. Background technique [0002] With the continuous development of the comprehensive economic level and the continuous advancement of the industrialization process, in the process of urbanization in the country, due to the continuous expansion of heating areas and the rapid increase in the number of heating users, industrial production requires more and more steam heating coefficients. Higher. Due to the limitation of technical conditions, the traditional heating management and regulation method makes the flow and temperature distribution unreasonable, resulting in excessive temperature loss and hydraulic loss, and hydraulic imbalance and thermal imbalance. [0003] Therefore, an effective heating control method is needed to solve the problems of irrational hydraulic distribution and thermal imbalance in the heat...
