Centralized Heating Network Intelligent Control Method

District Heating Network is one of the most important fundamental infrastructures of modern cities. The adjusting and control methods for the medium and large Heating Networks are thoroughly discussed firstly, and then the whole control scheme of the District Heating Network is put forward.In order to control the District Heating Network wholly, the Intelligent Coordination Control method is used, which has the global optimization performance. Furthermore, Expert-fuzzy Control is adopted to control the secondary supplying water temperature of each substation. On the basis of Shenyang Huanggu Heating Network, the design of Expert-fuzzy Control and the implementation of Intelligent Coordination Control are discussed thoroughly.In the last part, the macro control method is applied into the actual management and control system of the Huanggu Heating Network. From the running results, this control strategy is proved effective. The heat is distributed rationally throughout the heating network, and the heating quality is improved. Moreover, the goal of stable heating and well-proportioned heating is also achieved. Problems occurred during the running process are summarized in the paper. After analyzing possible reasons, an improved method is presented.
