Abstract

The invention discloses a method and a system for quantitative calculation of a heat supply system margin. This method is to first establish the heating system model of the information layer according to the structural parameters of the heating system and GIS system data, and establish the corresponding heat source constraints and heat network constraints, and perform thermal hydraulic simulation calculations. With the scoring method for the margin of the heating system provided by the present invention, the operation dispatcher can monitor the heating situation of the heating system according to the scoring result, avoid the phenomenon of insufficient heating as much as possible, and avoid the occurrence of insufficient margin in the heating network. Parts are optimized. The method and system of the invention can provide effective technical support for the planning and optimal scheduling of the heating system.

Description

technical field [0001] The invention relates to a heat supply system margin quantitative calculation method and system, belonging to the field of heat supply system optimization dispatching. Background technique [0002] With the widespread application of central heating in the heating network, the central heating system has become an important infrastructure in the city. The scale of the heating network has increased year by year, and the system has become more complex. The resulting elastic margin of the heating system ( That is, the satisfaction degree of heating demand, which can represent the heating capacity of the pipe network) and other issues have aroused widespread concern. [0003] In the process of heating system planning, design and operation, etc., operation dispatchers need to conduct quantitative analysis and evaluation of the margin of the heating system in order to monitor and optimize the scheduling of the heating system in real time. In the context of en...
