Elaboration of a mathematical apparatus for optimizing the automated control system of a heat supply system on the example of a building of a higher school

Abstract

Objective. The purpose of this work is to optimize the functioning of the automated control system of the heat supply system. The connection between the flow rate of flue gases at the inlet to the waste heat boiler and the temperature of the heat carrier at the far point of the consumer is subject to adjustment.Method. The methodological basis of the study is: the heat balance equation for the waste heat boiler of the combined cycle plant; principles for ensuring the specified parameters of heat supply to the consumer; equation of heat and mass transfer and sanitary standards for heat supply.Result. A mathematical apparatus has been developed that expresses the dependence of the flue gas flow rate at the inlet to the waste heat boiler and the temperature of the coolant in the heating device in the farthest room of the analyzed building.Conclusion. Optimization of the automated control system of the heat supply system on the example of a building of a higher school shows the possibility of improving the accuracy of control of the automated control system by the heating system. In the case of an additional installation, the narrowing of the error corridor occurs by 2.5 times.
