Abstract

The invention provides a gas supply and demand dynamic prediction system for steel enterprises and a method thereof, belonging to the technical field of gas prediction in steel industry. The system comprises a data acquisition subsystem, a data processing subsystem, a data modeling subsystem, a model verification subsystem, a model application subsystem and a computer network connecting each subsystem. The gas supply and demand dynamic prediction method comprises the following steps: abstracting generation and consumption characteristics of gas; qualitatively analyzing the generation and consumption characteristics of the gas; dynamically predicting and modeling in a sectional short-term method; and dynamically predicting the supply and demand of the gas. The system and the method of the invention have the advantages of proposing the sectional short-term dynamic prediction and modeling method which is based on historic statistic data, combines the production state information and comprehensively applies real-time data, the production state data and production process technical data. The invention provides decision-making support for distributing staff in short-term gas distribution, and simultaneously provides basic data for the implementation of various intelligent distribution schemes.

Description

technical field

[0001] The invention belongs to the technical field of gas forecasting in the iron and steel industry, and in particular provides a dynamic forecasting system and method for gas supply and demand in iron and steel enterprises, which are used for short-term gas forecasting in iron and steel enterprises. Background technique

[0002] At present, the research on gas forecasting in the iron and steel industry is a static forecast made in a relatively long period of time, without considering the production plan and equipment maintenance plan, that is, the forecast is made according to the normal development, without considering the impact of external events, Effective real-time dynamic forecasting cannot be realized, so how to conduct online dynamic forecasting based on dynamic working condition information and provide support for dynamic optimal scheduling is a very important research field.

[0003] The current systems and methods for dynamic forecasting of gas ...
