Abstract


The energy field of the development of China's science and technology field, where one of the priority themes of the industrial energy efficiency, energy consumption of per ton steel iron and steel enterprises in China is much higher than the world advanced level, Metallurgical energy-saving technologies and equipment is an important aspect of the industrial energy conservation. China's major iron and steel enterprises in the energy consumption of per ton steel is 10% higher than the foreign advanced level, traditional energy management model apparently has been unable to meet the large-scale iron and steel production, the need of high-speed and intense competition in the market, and certainly can not meet long-term national development plan requirements. Modern energy management energy management system (Energy Management System, abbreviated as EMS) is the inevitable road of the Chinese iron and steel enterprises in the context of this paper, the construction of iron and steel enterprises EMS system, combined with the energy system scheduling, energy scheduling balance theory, by the iron and steel joint analysis and research of the production process, the use of intelligent analysis techniques, the establishment of a large steel enterprise energy management system energy the scheduling event processing rule base, energy scheduling problem, determine the solution of the problem events, build event processing the rules library software system, and promote the construction of the iron and steel enterprises EMS system. The main results are as follows: (1) Research and analysis of large-scale iron and steel enterprises in joint production processes, process, comprehensive drawn steel enterprises production links between the energy consumption of secondary energy flow to the interaction between, and comprehensive analysis of enterprise-class energy balance relations, analyzed the energy scheduling events affecting the energy balance, lay the foundation for the establishment of the EMS system can tune the event rule base. (2) for the day-to-day production of iron and steel enterprises major subsystems: the gas system, water system, electrical system, etc., their production processes, technology and other aspects of in-depth analysis to identify the key events of the various aspects of energy scheduling and events mechanism for enterprise vertical strengthen energy management, energy scheduling balance. (3) mathematical modeling problem solving. Traditional energy analysis method of Analytic Hierarchy Process (Analytic Hierarchy Process, abbreviated as AHP) consistency test for AHP methods difficult problems in the energy system applications based on the combination of fuzzy math, fuzzy comprehensive evaluation theory, energy scheduling and energy The balance of mathematical modeling to identify the sort of impact energy scheduling events draw the level of the impact of various events on the energy balance model solution. (4) combination of Xiangtan Steel EMS system energy optimization scheduling event rule base, establish the analysis of various subsystems of the enterprise from the functional side, the the scheduling link can tune event rule base analyze energy production scheduling, and put forward solutions as well as solutions software. Xiang steel structure of the EMS system, external interface, database, such as a series of issues, in order to adjust the event rulebase better integrated into the EMS system.
