Abstract

The invention discloses a heat exchange station parallel water pump optimization control method and system under a distributed architecture. Based on the distributed control architecture, electromechanical equipment in a heat exchange station is upgraded by adding intelligent equipment, so that the whole control system of parallel water pumps becomes a distributed control system; an optimization model under a centralized framework is converted into a sub-optimization model under the distributed architecture through a penalty function, and a target function is improved by using an adaptive factor; the optimization model is solved by using an improved meta-start method SCAFOA, the optimization model is converted into an improved distributed fruit fly optimization algorithm D-SCAFOA based on the distributed architecture, and the improved distributed fruit fly optimization algorithm D-SCAFOA is downloaded to each controller so as to complete solving of the optimization model; and finally, on the basis of actual engineering data, combination and distribution optimization are conducted on a set of parallel water pumps of different models, so that the thermal load requirement of a terminal user is met. The problem of local optimum is avoided, and the method and system can be used for energy-saving optimization control of the parallel water pumps of the heat exchange station.

Description

technical field

[0001] The invention belongs to the technical field of optimization control of related equipment of heat exchange stations in district heating systems, and in particular relates to an optimization control method and system for parallel water pumps of heat exchange stations under a distributed architecture. Background technique

[0002] As the main energy-consuming equipment of the district heating (DH, District heating) system, the parallel water pump is driven by an electric motor. Globally, electric motors account for 46% of electrical energy consumption, with pumps and fans in water distribution systems accounting for as much as 60-70%. By updating the equipment or adding intelligent modules to the equipment in the building management system, 30% of energy can be saved. Therefore, the parallel pumps of the heat exchange stations in the DH system have great potential for energy saving. The operating efficiency of water pumps not only depends on the design,...
