Embodiment 1

[0028] A water conservancy adjustment algorithm for the secondary network of heat exchange stations, which divides the complex pipeline into multiple independent units, and calculates and analyzes the hydraulic characteristics in the complex pipeline through a recursive method according to the hierarchical relationship between each unit . The hydraulic characteristics of complex pipelines include the overall hydraulic characteristics of the pipeline and the hydraulic characteristics of each pipeline unit. The flow of the branch pipelines, so as to achieve the purpose of adjusting the flow balance of each branch pipeline.

[0029] Furthermore, when dividing complex pipelines, the heat user is the core, and the heat user inlet and outlet pipelines and accessories on the pipeline are regarded as a whole and an independent unit.

[0030] Furthermore, when dividing the hierarchical relationship between each unit, according to the order of water flow, the unit that flows through fi...

Embodiment 2

[0040] A water conservancy adjustment algorithm for the secondary network of heat exchange stations, which divides the complex pipeline into multiple independent units, and calculates and analyzes the hydraulic characteristics of the complex pipeline through an iterative method according to the hierarchical relationship between each unit .

[0041] attached figure 2 As a secondary network pipeline with three heat users, take this pipeline as an example, first divide the pipeline into three units, and the structure of each unit is as follows image 3 As shown, each unit includes water supply and return pipelines, heat users, and flow regulating valves. According to the direction of water flow, the level of the user unit 1 is the highest, followed by the level of the user unit 2, and the level of the user unit 3 is the lowest.

[0042] After the division is completed, the resistance characteristics of the series part and the resistance characteristics of the parallel part of e...

Abstract

The invention discloses a secondary network water conservancy adjusting algorithm for a heat exchange station, and belongs to the field of water conservancy adjustment. According to the scheme, a complex pipeline is divided into a plurality of independent units, and water conservancy characteristics in the complex pipeline are calculated and analyzed by a recursion method according to the hierarchical relationship among the units. The secondary network water conservancy adjusting algorithm for the heat exchange station has the beneficial effects that a complex pipeline is creatively divided into a plurality of independent units, the resistance characteristic of the whole pipeline is calculated in a recursion mode, the complexity of the pipeline is greatly reduced, flexible adjustment can be conducted according to different pipe networks. The difficulty of water conservancy characteristic calculation of the complex pipeline in actual conditions is reduced, and the efficiency of water conservancy adjustment of the secondary network of the heat exchange station is improved.
