Urban central heating system time-sharing and zoning regulation and control method considering building heat storage characteristics

Abstract

The invention discloses an urban central heating system time-sharing zoning regulation and control method considering building heat storage characteristics, and the method comprises the steps: dividing each heating station into a plurality of heat attenuation zones based on methods of heating station level load prediction, heat attenuation calculation, heating station heat storage characteristic calculation and the like, and summarizing the time-sharing characteristics of the heat load demands of each heating station; and obtaining an optimized heat station flow distribution strategy by using a heuristic optimization algorithm according to the heat attenuation condition and the heat storage characteristic of each heat station. According to the method, heat energy waste of the heat supply system can be effectively reduced, and the resource utilization efficiency of the system is improved.

Description

technical field [0001] The invention belongs to the field of advanced control of heat supply systems, and in particular relates to a time-sharing and zone-by-zone control method for urban central heating systems considering the heat storage characteristics of buildings. Background technique [0002] The heating system produces high-temperature hot water in the heat source plant and drives the hot water to circulate in the primary side pipe network to deliver heat energy to each heat station. Because the current heating system is relatively large and complex, and there are "near heat and far cold " phenomenon, which is caused by the fact that each thermal station is in a different heat attenuation zone. In addition, there are differences in heat consumption of different thermal stations in the time dimension. For example, the heating load demand of commercial office areas is concentrated in the daytime, but Certain residential areas (such as employee residences) have a concen...

[0002] The heating system produces high-temperature hot water in the heat source plant and drives the hot water to circulate in the primary side pipe network to deliver heat energy to each heat station. Because the current heating system is relatively large and complex, and there are "near heat and far cold " phenomenon, which is caused by the fact that each thermal station is in a different heat attenuation zone. In addition, there are differences in heat consumption of different thermal stations in the time dimension. For example, the heating load demand of commercial office areas is concentrated in the daytime, but Heating load demand in certain residential areas (e.g. staff residences) is concentrated at night

There are differences in time and space in the heating demand among the thermal stations. At present, there is no systematic control strategy, so that it is impossible to realize the precise supply of energy on demand. In order to avoid the problem of insufficient heating, the method of overheating is often adopted. Measures have caused problems such as energy waste and low utilization efficiency
