The invention proposes a whole network balance adjustment method based on load prediction and room temperature feedback correction. Most of the traditional heat supply adjustments are adjustments to heat sources or heat stations. This extensive adjustment method often causes large fluctuations in room temperature and even wastes energy. The control method proposed in this paper, on the basis of considering the adjustment of heat sources and heat stations, adds the adjustment research on the balance of the whole network. The goal of network-wide balance adjustment is to achieve the matching of supply and demand of the primary and secondary networks and the stability of the pipe network by adjusting the parameters of the heating system. In order to achieve this goal, it is necessary to determine the control cycle, adjust the time node, and perform periodic dynamic prediction of heating parameters, and center on the user's room temperature target value, and use the room temperature to make feedback corrections to the predicted water supply temperature, and finally form a model based on load forecasting and room temperature. The whole network balance adjustment method based on feedback correction. After the method is adopted, the fluctuation of the room temperature is relatively gentle, the phenomenon of overheating and overcooling is obviously reduced, and the effect of energy saving is remarkable.
