Shulou(Shulou.com)06/03 Report--

The energy quality of manufacturing enterprises has a direct relationship with the quality of products, and energy consumption directly affects the cost of high-consumption products, thus affecting the competitiveness of an enterprise. In addition, manufacturing enterprises, as major polluters, rational use and balanced allocation of energy play a vital role in environmental protection.

As the core of enterprise energy system, energy management system realizes:

1) Significantly improve the labor productivity of the enterprise energy management system.

2) On-line regulation of various energy media, making full use of secondary energy, ensuring economic and reasonable operation of production, and achieving energy conservation and environmental protection benefits.

3) In case of energy system abnormality and accident, the energy management system shall make timely, rapid and accurate disposal, control the impact caused by energy system failure to the minimum, and ensure the safe operation and stable energy supply of energy equipment.

As an important part of automation and informatization of energy management system engineering, energy management system not only plays an important role in unified dispatching of energy, optimization of energy balance, reduction of pollution emission, improvement of environmental protection quality, reduction of energy consumption per unit product and improvement of labor productivity, but also plays an important role in formulating and implementing accident plans, rapid analysis and timely judgment of accident causes, reasonable adjustment and balance of energy supply and demand, and analysis of energy performance based on objective information. Energy planning, energy quality management and energy consumption forecasting are all very effective.

1. The primary role of energy management systems

1) Improve the collection, storage, management and effective utilization of energy information

The energy management system analyzes, processes and processes energy data, so that energy dispatchers and professional energy managers can grasp the system status in real time and ensure that the system operates in the best state after reasonable adjustment of the system.

2) Decentralized control and centralized management of energy at company level

The energy management system will examine the basic management requirements of energy from the overall perspective of the company, meet the objective requirements of the decentralized characteristics of the energy process system and the centralized energy management needs, and adapt to the strategic development needs of the enterprise.

3) Reduce management links, optimize management processes, and establish an objective energy consumption evaluation system

To realize the process optimization and reengineering of energy monitoring and energy management based on information analysis, to meet the automation of energy equipment management and operation management, to establish an objective energy consumption evaluation system based on data, and to seek benefits from management.

4) Reduce energy operating costs and increase labor productivity

The construction of energy management system will play an important role in the reform of energy management system. One of its basic objectives is to simplify energy operation management, reduce manpower input in daily management, save human resource costs and improve labor productivity.

5) Accelerate system fault handling and improve response capability to plant energy accidents

EMS can quickly understand the operation status of the system and the influence degree of the fault from the overall point of view, take timely measures to limit the further expansion of the fault range, and effectively restore the normal operation of the system.

6) Energy conservation and environmental improvement through optimized energy dispatch and balanced command systems

Energy management system will optimize the way and method of energy management, improve the technical means of energy balance, real-time understanding of enterprise energy demand and consumption status, can effectively reduce pollution emissions, improve the recovery and utilization rate of secondary energy, adopt comprehensive balance and fuel conversion system method, so that the rational use of energy to 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 balance management and monitoring management of energy, but also create conditions for further data mining, analysis, processing and processing through the archiving and management of a large number of historical data.

2. the basic function of the system

As an integrated management and control system of the Company, the energy management center system of the whole plant will play an important role in energy production, management and ensuring the production stability of the main operation line, effectively improve the daily operation cost of the Company's energy system and improve the reaction capacity under abnormal conditions. In order to achieve these objectives and enable the energy management system to effectively serve production, the following subsystems are designed in the energy management system:

1) Information processing subsystem

The basic functions of the information processing subsystem are data acquisition and process monitoring. It is the basic subsystem of the energy management system, including the most basic SCADA system functions:

Data acquisition for different requirements (periodic acquisition, interrupted acquisition, SOE);

Classified data archiving (real-time data, short-term data, statistical data, historical data, records);

Real-time closed-loop regulation;

Logic analysis and processing (conditional interlocking, over-limit alarm, etc.);

Man-machine interface (process diagram, process curve, setting and query, etc.);

Management reports (instantaneous, punctual, daily, monthly, etc.);

Basic data processing, etc.

2) Fault handling subsystem

The fault handling subsystem mainly includes: monitoring; graded alarm (classified according to light and heavy faults); information recording and archiving (classified according to categories); basic fault analysis (sequence record analysis, online query, etc.).

3) Energy Management Subsystem

The basic functions of the energy management subsystem include:

Energy plan management (plan preparation, tracking, etc.);

Energy performance management (performance analysis, filing, inquiry, balance analysis, cost analysis, benchmarking analysis, etc.);

Energy quality management (quality analysis, quality tracking, trend assessment, over-limit warning, etc.);

Operation technical support (operation mode management, shutdown and restart management, operation evaluation, etc.);

Predictive analytics.

4) Other functions

Special monitoring and operation, in order to ensure that the system is foolproof, for the important monitoring objects of the energy management system, I/O is directly connected to the system instrument and operation panel standby safety measures, so that in the worst system state, the monitoring and control of these equipment is still possible.

According to the process system, the energy management system is generally divided into: power supply and distribution system, water system and power system.

Under the strategic layout in the field of electrical intelligence and energy management, Yuanzhongrui Technology has developed into a development service provider with a strong software R & D team in China. In the face of increasingly serious climate change issues, Yuanzhongrui Technology adheres to the mission of "environmental protection, energy conservation and love for the earth" and takes the lead in actively promoting energy conservation transformation in all factories within the Group to provide online energy consumption monitoring systems for industrial enterprises.
