Energy Management System Metallurgical Enterprise Introduction
Sep 26, 2017


Metallurgical industry, high energy consumption and environmental quality is not long-term problems plagued by metallurgical enterprises. The use of information technology as a platform, a combination of new technologies, new technology, supporting technology and management measures to reduce consumption, the formation of safe, stable, economical and efficient energy supply system for reducing steel production costs, improve environmental quality and improve product market competition Force has a very important meaning.

Iron and steel plant energy consumption accounts for about 20% to 40% of steel costs. Different levels of equipment, process, product mix and energy management will have different effects on energy consumption. Practical economic energy-saving technology, digital balanced transmission and distribution system and basic energy management is the modern iron and steel enterprises to achieve energy-saving basic technical measures. Construction of the company's integrated centralized energy management system is a digital energy management technical support measures, but also large-scale iron and steel enterprises to improve energy efficiency of major technical and equipment measures, should be a high degree of understanding from the enterprise development strategy to build enterprise energy management system, the necessity and urgency Sex. This paper introduces the structure and function of energy management system in metallurgical enterprises, and discusses its technical route and development.

The role of energy management systems

As an important part of automation and informationization of metallurgical enterprises, EMS plays an important role not only for unified dispatch of energy, to optimize gas balance, to reduce gas discharge, to improve environmental quality, to reduce energy consumption per ton of steel and to improve labor productivity. Development and implementation, rapid analysis of accident causes and timely judgment, reasonable adjustment and balance of energy supply and demand, energy performance analysis based on objective information, energy planning, energy quality management, energy system forecasting and so on are very effective The

1) improve the energy information collection, storage, management and efficient use of energy

EMS analysis, processing and processing of energy data, energy dispatchers and professional energy managers will be able to grasp the system in real time, through a reasonable system to ensure that the system is running at its best.

2) decentralized control and centralized management of energy systems at the corporate level

EMS will look at the basic management needs of energy in the company's global perspective, to meet the energy technology system dispersion characteristics and energy management needs to focus on the objective requirements to meet the strategic development needs of steel mills.

3) reduce the management links, optimize the management process, the establishment of objective energy consumption evaluation system

To achieve energy analysis on the basis of energy analysis and energy management process optimization and reconstruction, to meet the energy equipment management, operation and management of automation, the establishment of an objective data-based energy consumption evaluation system, to management to efficiency.

4) reduce energy system operating costs, improve labor productivity

EMS construction, the energy management system reform will play an important role. One of its basic objectives is to achieve simplified energy operation and management, reduce the daily management of human input, save human resources costs, improve labor productivity.

5) to speed up the system failure to improve the response to the whole plant energy accident

EMS can quickly understand the system from the global point of view, the impact of the degree of failure, in a timely manner to take systematic measures to limit the scope of the further expansion of the failure and effective recovery of the normal operation of the system.

6) Optimize energy dispatch and balance the command system, save energy and improve the environment

EMS will be through the optimization of energy management methods and methods to improve the energy balance of technical means to understand the realm of steel energy demand and consumption of the situation, can effectively reduce the blast furnace gas dispersion, improve the recovery rate of converter gas, the use of integrated balance and The fuel conversion uses a systematic approach that allows the rational use of energy to reach a new level.

7) to provide further conditions for mining, analyzing, processing and processing energy data

The construction of energy management system can not only solve the energy real-time balance management and monitoring management, but also through the large number of historical data archiving and management, in order to further data mining, analysis, processing and processing to create the conditions.

Application and Development of Energy Management System Technology

In recent years, energy management, operation decision support, forecast analysis and other aspects of the exploration, and achieved good results for the energy system security and stability and sustained economic operation provides a good support.

A number of integrated modern data analysis technology, forecasting technology, geographic information technology, scheduling decision optimization technology and other energy management system will emerge as the times require. ① data analysis Technical data analysis, statistics, data mining technology in different conditions, the application to the business staff to provide high-end integrated application and integration of information to help energy management personnel to improve their data application capabilities for the energy system planning, design , System optimization services. ② predictive evaluation technology SCADA system can complete the data acquisition is the basic measurement data, its integrity by many conditions. Using predictive evaluation techniques, you can understand the changing trends of the system (such as consumption) under a limited set of measurements. Such as the widely used in the power system in the short-term load forecast, the large iron and steel enterprises is also very necessary. ③ Geographic information technology Energy system data collection equipment and transmission network throughout the whole plant every corner, the use of geographic information technology, to achieve pipe network (line) geographic information and energy management system seamless integration of the operation and management personnel in a timely manner accurate To master the system information, command the operator to speed up the analysis and processing of system failure, improve the energy process system reliability and stability of a good guide. ④ scheduling optimization decision-making technology Large and medium-sized metallurgical enterprises of the complexity of the energy process system, so that online energy balance scheduling work can not achieve the desired state. Optimize the transmission of energy media, rational arrangements for the conversion of energy media, comprehensive production needs and economic requirements of the energy distribution, dynamic assessment of the energy system operating status, is to solve the safe operation of energy systems and economic operation of the inevitable requirements. The establishment of enterprise energy system scheduling decision optimization model is an effective means to achieve the above requirements.
