Shandong key use energy unit intelligence energy management system data collection platform development

The energy quality of a manufacturing company has a direct relationship with the quality of the product, and energy consumption directly affects the cost of high-consumption products, which in turn affects the competitiveness of an enterprise. In addition, as manufacturing companies are major polluters, the rational use and balanced deployment of energy plays a vital role in environmental protection.
As the core of the enterprise energy system, the energy management system, through the centralized monitoring and effective management of energy consumption, achieves:
1) Significantly improve the labor productivity of the enterprise energy management system.
2) On-line regulation of various energy media, make full use of secondary energy, ensure economic and reasonable operation of production, and realize energy-saving and environmental protection benefits.
3) In the event of energy system abnormalities and accidents, the energy management system will make timely, fast and accurate disposal, minimize the impact of energy system failures, and ensure the safe operation of energy equipment and stable energy supply.
As an important part of energy management system engineering automation and informatization, energy management system is not only important for unified energy dispatch, optimization of energy balance, reduction of pollution emissions, improvement of environmental protection quality, reduction of unit product energy consumption and improvement of labor productivity It also plays an important role in the formulation and implementation of accident plans, rapid analysis of accident causes and timely judgment and processing, reasonable adjustment and balance of energy supply and demand, and energy performance analysis based on objective information, energy planning, energy quality management, and energy consumption. Forecasts and so on are very effective.
1. The main role of the energy management system
1) Improve the collection, storage, management and effective use of energy information
The energy management system analyzes, processes and processes energy data , Energy dispatchers and professional energy management personnel can grasp the system status in real time, and after reasonable adjustments to the system, ensure that the system runs in the best condition.
2) Adopting decentralized control and centralized management of energy at the company level
The energy management system will examine the basic management needs of energy from the overall perspective of the company, and meet the decentralized characteristics and characteristics of the energy process system. Energy management needs centralized objective requirements to meet the strategic development needs of enterprises.
3) Reduce management links, optimize management processes, and establish an objective energy consumption evaluation system
Realize energy monitoring and energy management process optimization reengineering based on information analysis to meet energy equipment management , Operation management, etc., establish an objective data-based energy consumption evaluation system, and demand benefits from management.
4) Reduce energy operating costs and increase labor productivity
The construction of an energy management system will play an important role in the reform of the energy management system. One of its basic goals is to simplify energy operation management, reduce human input in daily management, save human resource costs, and improve labor productivity.
5) Speed ​​up system troubleshooting and improve the ability to respond to plant-wide energy accidents
EMS can quickly understand the operating status of the system and the impact of failures from a global perspective. Take systematic measures in time to limit the further expansion of the fault range and effectively restore the normal operation of the system.
6) Save energy and improve the environment by optimizing energy dispatch and balance command system
The energy management system will optimize energy management methods and methods to improve energy balance technical means, real-time Understanding the energy demand and consumption status of the enterprise can effectively reduce pollution emissions, improve the recovery and utilization of secondary energy, and adopt a 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 an energy management system can not only effectively solve energy real-time balance management and monitoring management, but also By archiving and managing a large amount of historical data, it creates conditions for further data mining, analysis, processing and processing.
2. Basic functions of the system
As the company’s integrated management and control system, the plant-wide energy management center system will play an important role in energy production, management and ensuring the stability of the main line of production. It will effectively improve the daily operating costs of the company’s energy system and improve the ability to respond under abnormal conditions. In order to achieve these goals 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 information processing subsystem The basic function is data acquisition and process monitoring. It is the basic subsystem of the energy management system, including the most basic SCADA system functions:
Data collection with different needs (periodical collection, interrupt collection, SOE);
Classified data archiving (real-time data, short-term data) , Statistical data, historical data, records);
real-time closed-loop adjustment;
logical analysis processing (conditional interlocking, over-limit alarm, etc.);
man-machine interface (process diagram, process curve, setting and Inquiry, etc.);
Management reports (instant report, punctual report, daily report, monthly report, etc.);
Basic data processing, etc.
2) Fault handling subsystem
The fault handling subsystem mainly includes: monitoring; hierarchical alarms (classified by minor and severe faults); information recording and filing (by category); basic faults Analysis (time 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 (actual performance Analysis, fallback, query, balance analysis, cost analysis, benchmarking analysis, etc.);
Energy quality management (quality analysis, quality tracking, trend evaluation, over-limit warning, etc.);
Operational technical support (operating mode Management, decommissioning management, operation evaluation, etc.);
Predictive analysis. 4) Other functions are very monitoring and operating. In order to ensure that the system is foolproof, for important monitoring objects of the energy management system, I/O is directly connected to the system instrument and operation panel as a backup security measure to ensure the worst In the state of the system, the monitoring and control of these devices are 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 of electrical intelligence and energy management, Yuanzhongrui Technology has developed into a development service provider with a strong software research and development team in China. In the face of increasingly serious climate change issues, Yuanzhongrui Technology adheres to the mission of “Environmental Protection, Energy Saving, and Love the Earth”, taking the lead in actively promoting energy-saving renovations in various factories within the group, and providing industrial enterprises with online energy consumption monitoring systems.
