1. Overview:
     Electric energy management system I used a variety of computer and communications technology and electronics sectors, the development of new high-speed MCU terminals together constitute a complete system, the system can be applied to the distribution transformer monitoring of the power industry, electricity on-site management, electrical load control, substation management,large users to remotely set ofcopy,the concentration of low-voltage meter and mining their own power monitoring or other applications.The system is one of the important system for State Grid Corporation to achieve the current distribution network automation.

2. System design features:
     The main station using redundancy to eliminate single equipment failure caused the loss of important functions.
     Systems availability year theory is greater than 99.99% . 
     System with hot and cold start function.
     Solid and strong real-time integration of system events to provide fast and constant responsiveness, in an efficient, fast, reliable and accurate way to reflect the system events.
     Computer with high utilization.
     System uses object-oriented support platform and operating, development platforms, improve software reliability, inheritable, maintainability and scalability.
     High security, using dual-network configuration and split / dual network redundancy mechanism, an important node in a dual redundant hot standby machine to improve system reliability and stability.
     Easy to maintain, the device has self-checking and on-line diagnostic and calibration capabilities, the system can be made with a convenient data backup and restore functions, the system should have remote maintenance,debugging and diagnostics.

3. System Function Description:

3.1 Data Acquisition
     Data Acquisition  support the GPRS, CDMA and other public network communications, support TCP,UDP communication.
     Can capture the measurement point of electric energy, instantaneous volume, network events, grid power quality data, to achieve automatic,complete, accurate, safe, timely, consistent, reliable and flexible collection, transmission and storage, to ensure data is not lost.
     Load management terminal types of incident can be reported promptly and take the formation of historical matters, saved to the history database for background processing.
     Supported the adoption of short message (SMS) approach to achieve alarm function, the module via SMS alarm messages can be sent to the duty officer cell phone.
