A heating pipe network system and self-adaptive control method

Abstract

The invention discloses a heating pipe network system and a self-adaptive regulation and control method. The heating pipe network system comprises a primary side self-compensation loop, a heat exchanger, a secondary side load adaptive loop and a self-adaptive master control system. The secondary side load adaptive loop obtains needed heat through the m parallel-connection heat exchangers from theprimary side self-compensation loop, and heat is reasonably distributed for m heat users under regulation and control of the self-adaptive master control system. Peak load shaving is conducted for periodic day-night change of heat supply waste heat through a tree-root-shaped grading energy storage device, and energy utilization efficiency of the system is improved. A dynamic model of a secondary side load adaptive branch is obtained through model on-line identification, optimal iterative control is conducted on heat supply of secondary side load loop through the minimum variance principle andthe self-adaptive control law so as to ensure the condition that control parameters of the self-adaptive master control system always adapt to actual heating characteristics of the secondary side loadadaptive loop, system control precision can be improved, pipe network heating quality is improved, and system energy consumption is reduced.

Description

technical field [0001] The invention relates to a heating pipe network system and an adaptive control method, in particular to a heating pipe network with adaptive characteristics designed to adapt to the dynamic change of outdoor temperature and the thermal characteristic change of the heating pipe network System and adaptive regulation method. Background technique [0002] Under the same climatic conditions, the heating energy consumption of residential buildings in my country is about three times that of developed countries, and the current heating energy consumption has accounted for 9.6% of the total energy consumption in the country. At present, my country's urban central heating system generally has problems such as unreasonable design of heating pipe network, unscientific heating management, complicated and backward control methods, and low heating efficiency. The traditional heating pipe network has no intelligent control, and mainly relies on the experience and jud...
