1. Overview
The user consumes 80% of the electricity in the entire grid. User-side intelligent power management is of great significance to users’ reliability, safety and energy saving. Build a smart electricity service system , comprehensive promotion of user-side smart meters，power management solution for intelligent power management terminal equipment, so as to realize two-way benign interaction between power grid and users. The research content that the user needs to solve urgently includes: advanced meter, intelligent building, smart appliance, value-added services, customer power management system, demand side management, etc.
Electric energy metering management system subdivides and counts the power consumption of users, and shows the use and consumption of each sub-item to managers or decision-makers with intuitive data and graphs, so as to find out the high energy consumption points or unreasonable energy consumption habits, effectively save electricity, and provide accurate data support for further energy-saving renovation or equipment upgrading for users.
2. Application
1）Office construction （business office、office building of state organs）
2）Commercial construction （Shopping malls, financial institutions .etc）
3）Tourist construction（hotel、restaurant、entertainment places，etc）
4）Science and education architecture( culture、education、science research、medical and health、sports architecture、etc)
5）Communication building(posts、telecommunications、radio、television、data centres、etc）
6）Transportation building (airport、station、wharf building）
3. Main Functions
1）Real-time monitoring
The man-machine interface of the system is friendly, and the operation status of distribution lines can be visually displayed in the form of distribution primary diagram, real-time monitoring of electrical parameters such as voltage、current、power、power factor and electric energy, dynamic monitoring of circuit breakers, disconnect, ground knives, and related fault and alarm signals in distribution loops.
2）Energy statistics report
The system supports the integrity of the system with abundant report forms. the system has the function of timing meter reading and summarizing, and users can freely inquire about the power consumption of each distribution node in any period since the normal operation of the system, that is, the statistical analysis report of the power consumption of the node's incoming wires and the power consumption of each branch circuit.
3）Runs statement
The system has the functions of storage and management of real-time power parameters and historical power parameters. All real-time collected data and sequential event records can be saved to the database. In the query interface, the system can customize the parameters that need to be queried, specify the time or select the latest updated record data, etc. and display them by report form. Users can customize daily and monthly reports according to their needs, support the export of Excel format files, and also export PDF format files according to user requirements.
4）User rights management
In order to ensure the safe and stable operation of the system, the user rights management function is set up. User privilege management can prevent unauthorized operation (such as name modification of distribution circuit, etc.). It can define the login name, password and operation authority of users at different levels, and provide reliable security for system operation, maintenance and management.
5）Communication status chart
The system supports real-time monitoring of the communication status of the devices in the access system, and can display the whole network structure of the system. It can diagnose the communication status of the devices on-line and automatically display the faulty devices or components and their faulty parts on the interface when network abnormalities occur. It is convenient for operation and maintenance personnel to grasp the real-time communication status of field equipment, maintain abnormal equipment in time, and ensure the stable operation of the system.
