Method for offline analyzing and online scheduling of byproduct gas of metallurgy industry

Abstract

The invention relates to a method for offline analyzing and online scheduling of byproduct gas of a metallurgy industry. A data collection server is connected with a gas producing and marketing project control system and can be used for carrying out the online scheduling on a byproduct gas supply and demand system of the metallurgy industry according to data provided by a system through a pipe network mathematical model, a gas supply and demand system prediction model and a gas supply and demand system optimal scheduling model. According to the method for the offline analyzing and the online scheduling of the byproduct gas of the metallurgy industry, the production rates of energy devices of iron and steel enterprises are greatly increased, and the condition that gas appliances work under a design load can be ensured, so that the operation efficiencies of the gas appliances are improved; the gas spreading can be effectively reduced, a secondary gas energy resource can be adequately adopted, and the reasonable operation of the producing economy can be guaranteed; the predicting and processing schemes can be timely, quickly and precisely made, and the influence caused by faults can be controlled at a lowest limit; the scheduling theory basis can be provided for a scheduler, the subjective blindness of the scheduling can be reduced, and a scheduling command can be timely and accurately issued; and important data parameters for leaderships to make decision to straighten the production of the iron and steel enterprises.

Description

technical field [0001] The invention belongs to the technical field of by-product gas application in iron and steel enterprises, and particularly relates to an off-line analysis and online scheduling method for by-product gas in metallurgical enterprises, which can comprehensively analyze the production and sales processes of three main by-product gas in iron and steel enterprises, and is used to realize the On-line optimal scheduling of by-product gas in enterprises. Background technique [0002] With the rapid growth of the iron and steel industry, as a high-consumption and high-pollution industrial "big household", the constraints on resource and energy consumption are obvious, and the contradiction between energy supply and demand is becoming increasingly prominent. Enormous pressure. At present, my country's iron and steel enterprises generally have problems such as low utilization rate of by-product gas and large amount of release (unused release), which not only caus...

Problems solved by technology

[0005] (1) Part of the measurement data is inaccurate: most of the measurement instruments in metallurgical enterprises are accurate, but as the production progresses, due to the harsh working environment of the instruments and the lack of maintenance by the operators, some of the instruments are inaccurate or even damaged, which seriously limits Measurement accuracy brings great difficulty to the optimal dispatch of by-product gas

[0006] (2) The tasks of power dispatchers are cumbersome: by-product gas dispatchers need to consult and monitor a large amount of production data every day, and analyze and summarize the data. When there are production fluctuations and disagreements in the use and distribution of by-product gas, coordination between the two parties is required and waiting for leadership instructions, which leads to heavy workload and cumbersome tasks for dispatchers

[0007] (3) There are many human interference factors: because the by-product gas itself has a certain value as an energy medium, energy costs need to be calculated in actual use, causing secondary enterprises to hope to optimize their use without affecting production, but secondary enterprises Often consider from a personal position, ignoring the overall interests

However, there is no good theoretical basis in the actual scheduling, which leads to the phenomenon of experience distribution and privilege distribution, which makes the secondary units restrict each other, and the use of gas is not objective and scientific.

[0008] (4) Scheduling cannot be quantified: due to the volatility of by-product gas production, dispatchers conduct balanced scheduling based on experience, so by-product gas users cannot know the method and instantaneous data in the process of balancing scheduling

Secondary by-product gas users can only see monthly and daily cumulative data in the monthly balance report, which makes it impossible for gas users to grasp the daily balance dispatch trends and compare and analyze the balance dispatch results in a timely manner, resulting in poor quantification of the balance dispatch results
