Six functions of smart energy management system
Smart energy that deeply integrates big data, Internet of Things, cloud computing, artificial intelligence and other new generation information technologies is a key path to implement the "dual carbon" strategy, and its carrier - smart energy management system - can provide energy companies with The monitoring and control of the entire process of water, electricity, gas, heating and other energy sources from transportation, application to recycling is integrated to achieve multi-dimensional statistics and analysis of energy data. Specifically, it includes energy consumption data monitoring, multi-dimensional energy analysis, and customized reports. It has six major functions: service, abnormal automatic alarm, intelligent equipment control and comprehensive system management and control.
1. Energy consumption data monitoring
Through the configuration of smart electricity meters, water meters, flow meters and other electric energy meters, online monitoring of energy consumption throughout the entire process of enterprise energy input, conversion, transmission, use and recovery can be achieved to realize the overall energy consumption of enterprises such as water, electricity, steam, gas, cooling and heating. , key energy-consuming areas and key energy-consuming units. At the same time, the system provides offline energy data entry functions, and provides data collection registration, data collection correction and other functions under authorization to meet the needs of energy application function verification and management business.
2. Multi-dimensional energy consumption analysis
Through energy consumption data modeling and statistics, we can establish an energy consumption analysis and energy efficiency analysis system based on energy type, energy consumption unit, time sharing, shift, production capacity and other dimensions, such as energy consumption proportion, ranking, benchmark, trend, cost, balance, etc. , including energy data comparison for the same period, energy data link comparison, energy consumption trend analysis, energy efficiency benchmark analysis and other systems to achieve the purpose of lean energy efficiency management through energy information management.
3. Customized report services
Establish multi-dimensional and multi-level customized energy consumption basic reports and advanced report systems based on energy type, energy consumption area, key energy-consuming equipment, time-sharing, production and non-production, energy billing, etc., to realize multi-dimensional query of energy data Function. The system displays energy consumption from different angles in the form of reports and charts, generates energy consumption reports regularly, and can output, print and send files in various formats such as Excel and PDF.
4. Abnormal automatic alarm
Provide abnormal alarm prompts for equipment operating status, energy consumption benchmarking, energy system energy balance analysis: analyze the location, time and cause of abnormalities. The system has functions such as customizing alarm categories, alarm levels, alarm odor values, etc. Set the alarm summary column and alarm content list on the operation interface. The alarm summary column is always at the top of the operation interface.
5. Equipment intelligent control
According to the energy supply parameters and process indicator requirements of energy supply and demand prediction, the company's power energy facilities are monitored and intelligently controlled. The controlled equipment includes high and low voltage power supply and distribution systems, power center boilers, refrigeration, air pressure, vacuum and other station buildings and workshop centers. Air conditioning system etc. It adopts PID adaptive control technology, mechanism and data modeling and simulation technology, frequency conversion energy-saving technology, variable water temperature energy-saving technology, etc. to achieve precise energy supply on demand.
6. System comprehensive management and control
Establish an enterprise-level energy management center to realize energy equipment file management, equipment maintenance management, inspection management, shift management, energy supply quality management, energy consumption data management, energy consumption analysis, energy efficiency analysis, energy information release, file management, and user management , role permission management, log management and other functions. The system realizes centralized management of the entire plant's energy system through large-screen display, central operation station, and visual human-machine interface.
Based on the energy flow analysis of the enterprise, the energy management system can conduct visual analysis of energy consumption measurement, energy balance and key energy indicators in each link of the energy purchase, conversion, transmission, use, recycling and reuse process, and establish an energy efficiency data visual analysis platform . Assist managers and operators to identify the keys to improving energy performance, strengthen energy management, reduce energy consumption, and provide customers with integrated energy management and energy-saving control solutions.
