Control method of whole network balancing of central heating system

Abstract

The invention relates to a control method of the whole network balancing of a central heating system, and belongs to the technical field of heating control and provides the control method of the whole network balancing of the central heating system which is capable of automatically identifying whether heating capacity of a heat source is enough or not, achieves the comfort heating when heating capacity of the heat source is enough and achieves the homogeneity heatingwhen heating capacity of the heat source is insufficient. The control method comprises the steps that predicting and calculating of thermal load, adopting dynamical real-time calculation for thermal load variation; disposing and calculating by collecting outdoor actual temperature; evaluating heating capacity of the heat source; using heating power condition of the worst beltway heating station in heat supply network for judging heating capacity of the heat source; according to the equivalent external temperature of the worst beltway heating station, realizing autobalance of the whole network between each heating station; identifying temperature control curve; introducing a thermal load correction factor and a relative discharge coefficient. The control method has wide use for central heating control.

Description

[0001] 1. Technical field [0002] The invention relates to a whole network balance control method of a centralized heating system, which belongs to the technical field of heating control. [0003] 2. Background technology [0004] In the heating system, there are mainly two problems to be solved. On the one hand, it is necessary to solve the problem of uniform heating among the heating stations in the whole network; balance problem. Most of the current control systems rely on dispatchers to solve these two problems. The quality of the control effect is limited by the level and responsibility of the dispatchers, and they cannot give full play to the role of the control system to achieve better energy-saving effects. [0005] 3. Contents of the invention [0006] In order to solve the problems existing in the prior art, the present invention provides a method that can automatically identify whether the heating capacity of the heat source is sufficient, realize comfortable heat...
