摘要:: 针对某大型钢铁厂压缩空气系统存在的设备调控缺乏统一管理、压力波动大、运行能效偏低及人工粗放管控等问题，为挖掘其节能潜力并实现智能化运行，采用以“系统能效最优与智能协同”为控制目标的压缩空气数字化智慧管理系统改造方案。其包括构建“控制中心—空压站—设备”三级管控架构，并集成负荷均衡控制、压力高精度稳压、AI预测与前馈控制以及多站协同等核心技术。改造后的运行数据表明，系统整体能效提升，平均电单耗从 $0.105\mathrm{kWh} / \mathrm{m}^3$ 降至0.100 $\mathrm{kWh} / \mathrm{m}^3$ ，管网压力波动在 $\pm 0.02\mathrm{MPa}$ 以内，为同类大型压缩空气系统的节能改造提供参考。

Abstract:: Addressing the issues existing in the compressed air system of a large steel plant, such as the lack of unified management for equipment regulation, significant pressure fluctuations, low operational energy efficiency, and manual extensive control, a transformation solution of a digital intelligent management system for compressed air was adopted to tap its energy - saving potential and achieve intelligent operation. Focuses on the control objective of "optimal system energy efficiency and intelligent coordination", this solution is implemented through the same system. It includes establishing a three-level management and control architecture of "control center - air compressor station - equipment", and integrating core technologies such as load balancing control, high - precision pressure stabilization, AI - based prediction and feedforward control, and multi - station coordination. According to the operational data after the transformation, the overall energy efficiency of the system has been improved, the average specific power consumption has decreased from $0.105\mathrm{kWh} / \mathrm{m}^3$ to $0.100\mathrm{kWh} / \mathrm{m}^3$ , and the pipeline pressure fluctuations have been within $\pm 0.02\mathrm{MPa}$ . This project provides a reference for the energy - saving transformation of similar large - scale compressed air systems.
