Gas optimization scheduling device of iron and steel enterprise

Abstract

The invention relates to a gas optimization scheduling device of an iron and steel enterprise. The scheduling device is connected with an energy management system and comprises a gas managing device, an optimizing device and a display device, wherein the gas managing device, the optimizing device and the display device are sequentially connected. The gas managing device acquires gas consumption amount historical data, gas generation amount historical data and storage amount data of a gas cabinet in each procedure through the energy management system of the enterprise to predict the production amount and the consumption amount of gas at present or in future; on the basis of the predicted data, the optimizing device adopts improved distribution estimation algorithms to optimize distribution of the gas, and the optimization principle aims to make the scattering amount smallest and the purchasing amount largest; the display device displays the gas distribution scheme obtained by the optimizing device for reference of users, so that the gas can be reasonably distributed. Compared with the prior art, the gas optimization scheduling device has the advantages of reducing the scattering amount and the purchasing amount of the gas and the like.

Description

technical field [0001] The invention relates to a gas dispatching device, in particular to a gas optimization dispatching device for iron and steel enterprises. Background technique [0002] Iron and steel is an industry with high energy consumption, high pollution and high emissions. Energy cost accounts for about 30% of its manufacturing cost, making full use of gas and reducing the emission rate is an important way to save energy and reduce emissions. Iron and steel enterprises involve many processes, and the types and quantities of gas demanded by each process are different, and the gas demand of a process at different times is also in a dynamic change. Due to the complex relationship between the gas and the process, a device is urgently needed to coordinate the work of the two. The device requires the ability to coordinate the entire gas management and have complete gas distribution control capabilities. [0003] In the Chinese patent "Prediction and balance method o...

AI Technical Summary

Problems solved by technology

However, this scheduling method only considers how to minimize the amount of gas emission, but does not take into account the gas purchase cost, and the simplex square calculation method adopted in this patent is prone to fall into an unsolvable dilemma

The most important thing is that the patent only dispatches the gas based on the predicted value at the current moment, without taking into account the gas surplus at the next moment
