Embodiment

[0036] Embodiment: A method for identification and evaluation of operation adjustment strategies common to heat exchange stations, wherein the principle of the identification and evaluation method is as follows: figure 1 shown. On the basis of actual data, obey the law of energy conservation and the heat balance relationship in the central heating system. According to the interpretation and analysis of the principle, the heat exchange station heat source side and the secondary side are interpreted from two levels, that is, the adjustment curve and the control mode.

[0037] At the level of the regulation curve, it is mainly reflected in how the water supply temperature responds to changes in external conditions. In theory, the relationship between heat supply and outdoor temperature is obtained from how the supply heat responds to changes in external conditions. Generally, it shows a linear relationship. In the quality adjustment mode of changing the flow rate in stages, the...

Abstract

The invention discloses an identification and evaluation method for a common operation regulation strategy of a heat exchange station. The data mining method of unsupervised clustering is adopted. Based on the law of energy conservation and the heat balance relationship of the central heating system, the present invention clusters the hourly data of the three characteristics of outdoor temperature, secondary water supply temperature, and secondary heat consumption using a Gaussian mixture model, and divides the unsupervised clustering results into heating time periods. Then identify the primary side strategy, secondary side strategy, heat consumption, and heat consumption per unit temperature difference in different heating time periods. Finally, the energy-saving potential of the heat exchange station operation adjustment control strategy is evaluated through heat consumption and heat consumption per unit temperature difference. The invention applies the data mining method of unsupervised clustering to the actual hourly operation data of the heat exchange station of the centralized heating system, and proposes a relatively general identification and evaluation method for operation adjustment strategies for different heat exchange stations, which can provide heat exchange Provide reliable reference experience for station operation optimization and energy conservation assessment.

Description

technical field [0001] The invention belongs to the technical field of central heating operation adjustment control, and in particular relates to a general operation adjustment strategy identification and evaluation method for heat exchange stations. Background technique [0002] With the continuous advancement of my country's economic growth and urbanization process, the energy demand structure is constantly changing. The energy-saving transformation of the central heating system and the construction of a large number of information systems are aimed at realizing "smart" heating. However, there are many problems in the operation and management of the central heating system, such as constant complaints from heat users, high energy consumption for heating, and continuous system failures. Among them, the operation adjustment of the heat exchange station is the main problem that plagues the operation management to realize "smart" heating. [0003] As the main parameter of the...
