The gas optimizing dispatching system comprises a production plan subsystem, a gas forecast subsystem, a system configuration subsystem, a self-adaptation subsystem, a gas optimizing dispatching subsystem and a saving and printing subsystem. The gas optimizing dispatching method comprises the following steps of: establishing a gas dispatching model; mathematically describing the gas dispatching model; improving the gas dispatching model; comparing and analyzing the gas dispatching model; and applying the gas dispatching model. The invention has the advantage of providing a whole set of system comprising production plan data acquisition, system parameter configuration, self-adaption constrained adjustment, gas dynamic forecast and the gas optimizing dispatching system. The invention also provides the gas optimizing dispatching method which has very high adaptation to an environment. In the self-adaptation selectable constrained gas optimizing dispatching method of the steel enterprises, a user can accomplish all functions from data extraction to gas dispatching by only using the system without adding other extra work.

Description

technical field [0001] The invention belongs to the technical field of iron and steel gas dispatching, and in particular provides an adaptive optional constraint iron and steel enterprise gas optimization dispatching system and method, which are used for iron and steel enterprise gas optimization dispatching. Background technique [0002] The level of a company's gas production and the balance between gas supply and demand have a great impact on the company's product costs and energy consumption. Comprehensively analyzing the gas situation of iron and steel enterprises and scientifically formulating countermeasures for the balance between gas supply and demand are of great significance to the development of steel production, reduction of energy consumption and improvement of the environment. [0003] At present, there are systems and methods related to gas dispatching, such as the invention patent "Automatic optimal dispatching system and method of iron and steel energy base...

Problems solved by technology

[0003] At present, there are systems and methods related to gas dispatching, such as the invention patent "Automatic optimal dispatching system and method of iron and steel energy based on comprehensive data sources", which provides an automatic optimal dispatching system and method of iron and steel energy based on comprehensive data sources Metallurgical automation research and design Court ZL 200710178959.4, but this invention patent did not conduct in-depth exploration on gas dispatching, but only comprehensively analyzed the energy dispatching system and method of iron and steel enterprises, and did not consider the issue of gas dispatching enough, which caused certain limitations in practical application. Gas system balance practice" starts from the actual situation of Baosteel, combined with the actual equipment of the enterprise, pointing out that the key to gas scheduling lies in the monitoring and adjustment of the system during operation. The counter is the most important monitoring content and explains how to dispatch the gas. The article explains in detail the specific process and goals of the dispatch, but it is limited to practical experience and there is no certain theory as a guide. The document "Optimization of Gas System in Iron and Steel Complex Using "Metallurgical Energy 2005" to analyze the fluctuation range of various gas consumption and generation, and taking into account the energy utilization rate of each equipment to obtain the heat balance relation, a simple linear programming model was established under certain process conditions

Since the actual energy consumption of each equipment is fully considered, it has more practical significance; but the model is simple and cannot meet the requirements of gas distribution well. The document "Discussion on Gas Balance Problems in Iron and Steel Enterprises" points out that gas scheduling is divided into static scheduling and Dynamic Scheduling China Energy Conservation 2004 specifically analyzed the three major causes of gas fluctuations, and finally pointed out that the key to gas dispatching is to ensure that the gas does not fluctuate, and proposed three kinds of manual dispatching experience, but there is no model as a guide
