Abstract

The invention provides a centralized heating secondary network operation adjustment method, and relates to the technical field of heat supply adjustment. The method solves the problems that according to an existing heat supply system, limitation exists in application in different degrees due to design defects, expected effects of operation adjustment are difficult to achieve, and an adopted adjustment method is complicated in structure, long in operation time, large in calculation amount and the like. According to the centralized heating secondary network operation adjustment method, a three-layer forward-direction-type neural network is combined with PID, and the return water temperature of a secondary network is automatically controlled. A set value prediction model of a centralized heating secondary network temperature control system is built through an RBF neural network, the return water temperature of the secondary network is predicted in real time through a well-trained RBF prediction model by means of five data collected on site, namely primary network supply water temperature, primary network supply water flow, outdoor temperature, secondary network supply water temperature and secondary network supply water flow, and the obtained value serves as a set value of the centralized heating secondary network temperature control system. According to the method, heating quality of the system is guaranteed through automatic control, and reasonable utilization of energy is achieved.

Description

technical field [0001] The invention relates to the technical field of heating regulation, in particular to a method for regulating the operation of a central heating secondary network. Background technique [0002] At present, the operation regulation method applied to the non-linear, large inertia, and large time-delay system of the central heating system mainly includes the following methods: [0003] 1. The current operation adjustment method of the secondary network of central heating mainly adopts the following two methods: [0004] (a), manual adjustment. The current operation regulation of the heating network is to assign at least two on-duty personnel at each heat exchange station. The on-duty personnel adjust the circulating water flow of the secondary network according to the outdoor temperature and the water supply temperature of the primary network according to certain operating rules to meet the heating needs of users. . This method has the problem of manpow...
