Problems solved by technology

This kind of control method requires the debugging personnel to have certain experience. At the same time, in order to obtain the control value that meets the requirements, it is necessary to repeatedly test the value, and because many households do not have online indoor thermometers, it is difficult to evaluate the quality of heating in a timely and objective manner.
As a multi-coupling system, the entire heating pipeline is a multi-coupling system. If one variable is changed, other variables will also change accordingly. If the debugging is not up to standard, it will easily lead to hydraulic imbalance and thermal imbalance, resulting in uneven heating or heat waste, reducing heating. quality, increasing heating costs

Embodiment Construction

[0086] Specific embodiments of the present invention will be described in detail below.

[0087] like figure 1 As shown, a multi-mode control method for heat exchange stations based on load forecasting includes the following steps:

[0088] 1. Load forecast calculation

[0089] (11), choose the judgment condition:

[0090] Take a number of indoor temperature data (N, T) from the historical indoor temperature data, N is the date, T is the daily average temperature, let the number of days when the average temperature T satisfies the condition be n, then

[0091] When 18

[0092] In other cases, n=n;

[0093] Until the historical data browsing is completed;

[0094] If n>30, select big data calculation and enter step (13);

[0095] If n≤30, select the theoretical calculation heat load and enter step (12);

[0096] (12) Calculate the heat load theoretically:

[0097] (121) Through the design specification table, determine the thermal index q of different types...

Abstract

The invention relates to a heat exchange station multi-mode regulation and control method based on load prediction. The method comprises the following steps: (1) load prediction calculation: (11) selection of judgment conditions; (12) theoretically calculating the thermal load; (13) selecting big data to calculate the thermal load; (2) the debugging method: (21) first-network electric valve control; and (22) second-network circulating pump control. The heat exchange station multi-mode regulation and control method based on load prediction has the following beneficial effects that 1, through multi-level correction and big data calculation of theoretical calculation, a more accurate heat load can be calculated, and in actual operation, the heat supply quality is guaranteed, and unnecessary energy consumption is reduced; and 2, multiple modes can meet the requirements of different field conditions, can be used for multiple heat exchange stations, and have wide applicability and stronger application capability.

Description

technical field [0001] The invention relates to a multi-mode control method for a heat exchange station based on load forecasting. Background technique [0002] At present, the heating method used by thermal companies to guide heat source plants often adopts theoretical calculations, stipulates production indicators, and subordinate heat source plants perform production tasks. [0003] When thermal imbalance occurs during the operation adjustment process of the actual heat exchange station, it is mainly necessary for the commissioning personnel to adjust according to experience. The flow regulation of the network, and then realize the heat regulation of the primary network and the secondary network. This kind of control method requires the debugging personnel to have certain experience. At the same time, in order to obtain the control value that meets the requirements, it is necessary to repeatedly test the value, and because many households do not have online indoor thermo...
