Problems solved by technology

[0002] The principle of the current high-temperature and large-capacity heat storage system is to increase the heating capacity when it detects that the heat storage capacity is low; when the heat storage capacity is high, reduce the heating capacity to control the heat storage of the heat storage body, and the system control method delays the action. The action of the system cannot be determined in advance, resulting in a large difference between the heating supply and the actual demand

Embodiment Construction

[0059] As shown in the figure, the present invention includes a sample data processing part, a heat storage system prediction model part and a heat storage control process part.

[0060] The sample data processing part includes the following steps:

[0061] Step 1: Collect the local historical temperature data and the historical heat storage data of the heat storage body.

[0062] Step 2: Perform data preprocessing on the collected data. Use the numerical filtering method when the heat storage process is slow; use the missing data processing method for the missing data when the collected data is not enough to make a reasonable analysis; avoid rare occasional extreme cases that cause unnecessary data analysis The influence of the data is normalized, and the extreme cases in the sample are cut off.

[0063] Step 3: Carry out correlation analysis on the processed data, analyze the correlation, and determine the correlation coefficient between the two data to complete the prepro...

Abstract

The invention relates to a high-temperature large-capacity heat storage system control method based on meteorological prediction, which realizes the prediction of automatically determining the heat storage capacity of a heat storage system along with the change of weather and can be used for collective heat supply, heat supply, heat storage of a distributed heat storage system, heat storage capacity of a peak regulation power station and the like. The invention mainly provides a new control method, and the heat storage capacity is directly determined according to the weather prediction of theprevious day. The method comprises a sample data processing part, a heat storage system prediction model part and a heat storage control process part. The sample data processing part comprises the following steps: step 1, collecting local historical air temperature data and heat accumulator historical heat accumulation amount data.

Description

technical field [0001] The invention relates to a control method for a high-temperature and large-capacity heat storage system based on meteorological prediction, which realizes the prediction of the heat storage capacity automatically determined by the heat storage system as the weather changes, and can be used for collective heat supply, heat supply, and heat storage of distributed heat storage systems. Control of peaking power station heat storage, etc. Background technique [0002] The principle of the current high-temperature and large-capacity heat storage system is to increase the heating capacity when it detects that the heat storage capacity is low; when the heat storage capacity is high, reduce the heating capacity to control the heat storage of the heat storage body, and the system control method delays the action. The action of the system cannot be determined in advance, resulting in a large difference between the heating supply and the actual demand. Contents ...
