Metallurgical gas integrated dynamic balance scheduling system and method

Abstract

The invention discloses a metallurgical gas integrated dynamic balance scheduling system and method, and belongs to the technical field of multiple gases balance scheduling control. Based on real-time state data and production plan data, and on the basis of a combined model of a K-Nearest Neighbor(KNN) algorithm model, a back-propagation neural network algorithm model, a RBF neural network learning algorithm model, prediction is conducted on gas production/consumption value, gas tank place value, and pipe network fluctuating value in a future time period, and corresponding prediction values are obtained, and in accordance with a gas balance scheduling expert database, dynamic balance scheduling on the gas is completed in combination with the aforementioned prediction values. The system and the method of the invention are advantaged in that on the basis of the completion of the gas balance scheduling, functions of online adding algorithm model are expanded, and functions of online correcting balance scheduling expert database is expanded, and in cases that stable and safe operation of a gas system, real-time correction of system defects are achieved, so that gas can be more reasonably utilized and usage efficiency of gas is provided.

Description

technical field [0001] The invention belongs to the technical field of various gas balance dispatching controls, and in particular relates to a metallurgical gas comprehensive dynamic balance dispatching system and method. In particular, it proposes a method and system based on the operation plan, using the forecasting method of different categories and cooperating with the gas dispatching expert database to complete the dynamic dispatching of the gas comprehensive balance. Background technique [0002] Energy saving, consumption reduction, and green production are the slogans called for under the new normal of today's economy. As a metallurgical industry with high energy consumption, high pollution and high emissions, it is even more necessary to complete the improvement of new energy-saving technologies. One aspect that directly affects the energy consumption cost and the effect of energy saving and emission reduction of the entire metallurgical enterprise is whether the ...

Problems solved by technology

[0003] Existing metallurgical enterprises mostly rely on experience in the way of gas dispatching. In practical applications, this mode has a certain degree of blindness, and the dispatching has a certain hysteresis. When there is an abnormality in the gas cabinet counter or gas production and sales, it cannot be adjusted in time. To respond, the control accuracy is poor, the level of automation and informatization is low, and it is easy to cause waste of resources and air pollution. At the same time, because the gas cabinet cannot be controlled in time, it may cause hidden dangers in production safety.
