Abstract

The invention relates to a novel thermal inlet load dynamic prediction and control method, mechanism and data hybrid driving is adopted, target energy consumption accurate control is taken as a core, a steady-state heat transfer equation and a machine language are fused for modeling, and the method is simple and feasible, has self-learning, self-adaption and self-optimization-approaching capacities, is suitable for time-division, time-division and temperature-division accurate heat supply, and has a wide application prospect. The condition of user side oversupply can be effectively avoided; and in combination with adjustment of the heat source side of the energy center, efficient operation of the whole system is facilitated, on-demand heat supply is achieved when the time scale and the space scale are small enough as much as possible, and energy conservation and emission reduction are remarkably achieved while the heat requirement of a user is met.

Description

A new dynamic prediction and control method of thermal inlet load technical field The invention belongs to the field of heat supply operation regulation, and is specifically related to a novel thermal inlet load dynamic prediction and control method. Background technique [0002] In the northern regions of my country, central heating is the most common form of heating. Precise heating on demand is to ensure that users can supply Thermal comfort while achieving significant energy saving and emission reduction. Due to the large thermal inertia of the system, the building Thermal inertia, as well as the time-varying thermal mode of the user, lead to limited transient adjustment response capability of the system, and the actual heating process is There are varying degrees of mismatch between supply and demand and wasted energy. According to statistics, the heating area in northern my country exceeds 20 billion square meters, and the current average energy consumption p...
