Abstract

The invention discloses a control method and system for a secondary network of a heat exchange station. The control method includes: obtaining the detection value of the return water temperature of the secondary network and the detection value of the indoor temperature; The water temperature correction value calculates the return water temperature control setting value of the secondary network; compares the return water temperature control setting value of the secondary network with the return water temperature detection value of the secondary network to obtain the return water temperature control error; according to the return water temperature control error and The physical parameters of the secondary network calculate the opening degree change value of the secondary network control valve; adjust the opening degree of the secondary network control valve according to the change value of the opening degree of the secondary network control valve. The control method and system of the secondary network of the heat exchange station of the present invention improve the thermal balance and hydraulic balance degree and control accuracy of the secondary network and the heat user, provide necessary conditions for the optimized operation of the heat exchange station, and meet the heat supply quality requirements of the heat user. Make full use of the free heat of the system, reduce system energy consumption and pollutant emissions, and reduce labor costs and labor intensity.

Description

technical field [0001] The invention relates to the technical field of heat exchange station control in a central heating system, in particular to a method and system for controlling a secondary network of a heat exchange station. Background technique [0002] At present, the secondary network carried by the heat exchange station of the central heating system is one of the main links to ensure the heating quality of heat users, the balance of pipe network conditions, and energy saving and consumption reduction. On the premise that the heat source of the heating system, the primary network and the heat exchange station have optimized control means and measures, the secondary network becomes the "last mile" of the heating system. Most of the existing secondary network building / unit thermal inlets only have the function of valve isolation. Even if the regulating valve is installed, it is rarely adjusted or the function fails in actual operation; in addition, some secondary netw...
