1. Improve the collection, storage and management of energy information and the effective use of energy.
EMS analyzes, processes and processes energy data, so that energy dispatchers and professional energy managers can grasp the system status in real time, and make reasonable adjustments to the system to ensure that the system runs in the best state.
2. The company-level energy system adopts decentralized control and centralized management.
EMS will examine the basic management requirements of energy from the overall perspective of the company, meet the objective requirements of decentralized energy technology system and centralized energy management requirements, and adapt to the strategic development needs of steel mills.
3. Reduce management links, optimize management processes and establish an objective energy consumption evaluation system.
Realize the process optimization and reengineering of energy monitoring and energy management based on information analysis, meet the automation of energy equipment management and operation management, establish an objective energy consumption evaluation system based on data, and seek benefits from management.
4. Reduce the operating cost of energy system and improve labor productivity.
The construction of EMS will play an important role in the reform of energy management system. One of its basic goals is to simplify energy operation management, reduce the human input in daily management, save the cost of human resources and improve labor productivity.
5. Accelerate the fault handling of the system and improve the ability to deal with energy accidents in the whole plant.
EMS can quickly understand the running state of the system and the influence degree of the fault from a global perspective, and take systematic measures in time to limit the further expansion of the fault range and effectively restore the normal operation of the system.
6. By optimizing the energy dispatching and balanced command system, energy can be saved and the environment can be improved.
EMS will know the energy demand and consumption of steel mills in real time by optimizing the ways and methods of energy management and perfecting the technical means of energy balance, which can effectively reduce the discharge of blast furnace gas and improve the recovery rate of converter gas, and adopt the systematic method of comprehensive balance and fuel conversion to make the rational use of energy reach a new level.
7. Provide conditions for further mining, analysis, processing and processing of energy data.
The construction of energy management system can not only effectively solve the real-time energy balance management and monitoring management, but also create conditions for further data mining, analysis, processing and processing by archiving and managing a large number of historical data.
The basic technical route is:
1, planning advanced energy SCADA system
The energy technology system is decentralized, wide in scope and large in quantity. The selection of data acquisition objects should be carefully selected according to the actual requirements of process monitoring, the requirements of transportation, distribution and balance of energy system, and the requirements of precision and granularity of energy management. The data acquisition system should be decentralized to reduce system risks and improve system security and maintainability.
2. Design a centralized and unified "digital" energy transmission and distribution and balance control application system.
Dispatcher can directly control and adjust the dynamic balance of the system in the energy control center, reduce management and control links, and improve work efficiency, especially in the processing and command of process system failure and real-time system adjustment, which shows great advantages.
3. Establish a systematic energy cost center management platform.
EMS fully embodies the essential management characteristics of energy system in system planning, architecture design, function configuration and application integration, and allocates energy management elements according to the principle of maximum benefit, and evaluates the energy production process and consumption process through technical means such as energy management system planning, performance analysis, quality management, balance prediction and energy consumption evaluation.
4. Seamless integration of energy management with ERP or MES system.
One of the basic management tasks of energy management system is to provide complete energy system analysis data and analysis results to ERP system according to the cost-centered model. ERP will also provide the company's production plan, maintenance plan and related production performance information to the energy management system according to the needs of energy management and forecast analysis.
