Problems solved by technology

At present, China's iron and steel industry control technology systems are mainly distributed distributed control systems, PLC control systems and traditional intelligent instrument control systems. These systems only realize the centralized control of various production lines in the iron and steel industry. Enterprises conduct centralized management, analysis and forecasting of energy, so iron and steel enterprises cannot achieve comprehensive energy balance, reasonable distribution and optimal control of energy management, and cannot provide energy-saving solutions for economic operation
[0003] Although most of the iron and steel industry currently adopts frequency conversion technology and computer technology, the purpose is only to achieve a single centralized control, monitor the operating status of the main equipment, operate commands and set system parameters, etc., without energy optimization models and advanced energy-saving technologies. Iron and steel enterprises The equipment cannot consume energy on demand, so that the energy can be used rationally

Description

(1) Technical field [0001] The invention relates to an intelligent energy-saving control device for energy management, energy efficiency analysis and prediction, in particular to an energy-saving steel industry energy efficiency tracking control management device and an energy-saving control method. (2) Background technology [0002] Since 1980, the energy consumption of China's iron and steel industry has always accounted for about 10% of the country's total energy consumption. Compared with the international level, the iron and steel industry has great energy-saving potential. At present, China's iron and steel industry control technology systems are mainly distributed distributed control systems, PLC control systems and traditional intelligent instrument control systems. These systems only realize the centralized control of various production lines in the iron and steel industry. Enterprise energy is managed, analyzed and forecasted in a centralized manner. Therefore, ir...
