Optimization Design Of Automatic Control System For Central Heating In ZhengZhou Airport Economy Zone

As an important component of the municipal infrastructure,the progress of urban central heating project is a significant mark of cities' development,which also has a critical influence on the quality of local atmosphere and environment.With the continuous modernization of cities,in this stage,the methods to improve the level of central heating automation and achieve the objective of energy conservation and emission reduction have become the research focus for the heating enterprises.1.This article systematically analyses the status quo of heating and the demand for development in Zhengzhou Airport Economy Zone in the first place.2.Based on the status quo of heating and the demand for development in Zhengzhou Airport Economy Zone,this article selects the functionality and strategy of automatic control in central heating for our company and optimizes the design of automatic control system according to the demand,which can ensure the positive influence of the automatic control system for central heating on the reduction of heating cost,the improvement of heating efficiency and the guarantee of heating safety.According to the control requirements of the whole system,the automatic control strategy of heat exchange station is emphatically introduced.3.According to the current situation of limited heat sources in Zhengzhou Airport Economy Zone,it can be regarded as a multi-objective optimization control problem to realize the control of the average temperature of the supply and return water of the secondary network to reach uniform heating by adjusting the primary network flow rate of each heat exchange station.To solve this problem,NSGA-? algorithm,which is suitable for solving multi-objective optimization problem is selected for calculation in this article.Through numerical experiment analysis,simulation results show that NSGA-? algorithm is feasible and effective to achieve uniform heating for flow regulation of heat exchange station,which provides an optimization scheme for the automatic control system of central heating in Zhengzhou Airport Economy Zone.
