Heat supply pipe network adjusting method and system

Abstract

The invention discloses a heat supply pipe network adjusting method and system. The heat supply pipe network adjusting method comprises the step of obtaining a secondary network return water supply temperature reference value and a secondary network water pump head reference value on the basis of historical operation data of heat supply pipe network measuring points, the step of adjusting a secondary network return water supply temperature value to the secondary network return water supply temperature reference value and adjusting a secondary network water pump head to the secondary network water pump head reference value to achieve adjustment of temperature and flow of a secondary network, the step of obtaining a primary network return water supply temperature reference value, a primary network water pump head reference value and a primary network valve opening reference value on the basis of the historical operation data of the heat supply pipe network measuring points after the secondary network is adjusted, and the step of adjusting primary network return water supply temperature to the primary network return water supply temperature reference value, adjusting primary network valve opening to the primary network valve opening reference value and adjusting primary network water pump head to the primary network water pump head reference value to achieve adjustment of temperature and flow of a primary network, thus the whole network can be adjusted. Because the relationship between heat supply pipe network operation rule and outdoor temperature is obtained based on training of the historical operation data of the heat supply pipe network measuring points, waterpower and heat balance of the heat supply pipe network system is taken into consideration as a whole, heat distribution in accordance with the order is realized, the indoor temperature difference phenomenon of near-end users and far-end users is avoided, and heat supply is more balanced.

Description

technical field [0001] The invention belongs to the technical field of urban central heating, and in particular relates to a method for adjusting a heating pipe network. Background technique [0002] Urban central heating is a practical heat supply method in which steam and hot water generated by centralized heat sources are supplied to a city or some areas through a pipe network for production and life. It consists of three parts: heat source, heat network and heat users; among them, the heat network includes Heat station and pipeline. [0003] One of the central problems of urban central heating is: low energy utilization rate, coupled with insufficient energy reserves, energy saving and emission reduction are particularly important. With the shortage of energy in the world, more and more attention has been paid to energy-saving work. The vision of central heating in my country has made great progress in terms of scale and technology. [0004] At present, there are two m...
