AI Technical Summary

Technical Problem

Existing natural gas high-temperature flame gas supply systems suffer from lag, model mismatch, and high energy consumption when faced with sudden load changes, making it impossible to achieve high-precision, low-energy stable gas supply control.

Method used

A dual closed-loop control architecture is constructed using a production planning acquisition module, a load forecasting module, a model calibration module, and a forward-looking control module. By acquiring future production scheduling data, load forecasting and model calibration are performed, and forward-looking control is achieved using a model predictive controller. Combined with a booster pump driven by a frequency converter, smooth gas supply control is realized.

Benefits of technology

It achieves ultra-steady-state control of gas supply pressure, reduces system energy consumption, extends equipment life, and improves the intelligence level and reliability of the gas supply system.

Abstract

This invention relates to the field of industrial automation control technology, and discloses an energy-saving natural gas high-temperature flame gas supply control system and method, comprising: a production plan acquisition module for acquiring production scheduling data for a future preset time period from an upper-level information system; a load prediction module for generating an initial total load prediction curve based on the production scheduling data; a model correction module for performing online dynamic correction of the load prediction model of the load prediction module based on the deviation between the actual total gas consumption of the gas supply system and the initial total load prediction curve, and outputting a corrected total load prediction curve; and a look-ahead control module for generating control commands for the gas supply system actuators in advance based on the corrected total load prediction curve to stabilize the output pressure of the gas supply system. This invention achieves a fundamental leap from passive response to proactive anticipation in the gas supply control system, fundamentally avoiding the inherent lag of traditional feedback control.
