Embodiment Construction

[0040] The specific technical solutions of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0041] See Figure 1-Figure 4 , a heat balance control method for the central heating network, which is based on a two-stage control mode on the heat source side and the primary side of the heat exchange station in central heating. Forecast and realize heat demand feed-forward guidance; on the primary side of the heat exchange station, according to the expert control experience, determine the method of setting the secondary supply and return water temperature and the valve position adjustment strategy of the whole network, and realize the automatic control of the regulating valve on the primary side of the heat exchange station .

[0042] For the heat source, first, based on the meteorological data and thermal data in the historical data, the least square method is used to fit the regression curve of the outdoor temperatur...

Abstract

The invention relates to a centralized heating whole-network heat balance control method, in particular to a control system which is charged on area, which can eliminate the heat imbalance of the whole network and balance the heating effect. The control method adopts different control strategies for a heat source and two links of a primary side in the heating system so as to meet the requirement of users. For the heat source, the online prediction of the heat load is realized according to external temperature variation, and a running instruction is supplied for the heat source; a uniform control strategy is adopted for a primary network, automatic adjustment of a primary valve of a heat exchanging station of the heat network can be realized, a weighted value can be manually given to a special heat exchanging station, and the heat imbalance degree is used for analyzing and evaluating a whole-network heat balance control effect; and the control method can effectively solve the problems of the heating system such as imbalance heat and energy waste, a great amount of manpower and material resource can be saved in the adjustment process of the heat network, and the balance and consistency of the heat supply effect can be guaranteed.

Description

technical field [0001] The invention relates to a heat balance control method for the central heating network, which is used for the management and control of the central heating pipe network, and is the core technology to realize the integration of complete management and control, so that the central heating pipe network can save energy and meet the heat demand of users , especially for heat adjustment guidance and whole-network heat balance control. Background technique [0002] At present, most of the central heating systems in China adopt the operation mode of charging according to the area, and mainly use the high-temperature hot water on the primary side of the heat exchange station to be converted into secondary low-temperature hot water suitable for heat users through heat exchangers for heating. The average temperature of the secondary supply and return water can reflect the indoor temperature of the user. Therefore, how to adjust the primary flow rate to ensure the ...
