Smart grid electricity information collection program has a strong data management and processing power, a strong security mechanism for a meter to install more concentrated areas (such as residential buildings, etc.) meter reading and power quality monitoring. The whole program consists of master station system, concentrator, collector, HHU, smart meter. System master to the concentrator using GPRS technology and concentrator to the collector using PLC communication technology, the collector to the smart meter using RS485 communication technology. Intelligent substation on-line monitoring system to achieve the information sharing platform, the system framework network, equipment status visualization, monitoring target panorama, the whole station information digitization, communication protocol standardization, monitoring function component, information display integration, real-time collection station equipment State data, a comprehensive diagnostic analysis and a full life assessment. On the one hand, the substation monitoring system is a separate internal interconnection equipment network, on the other hand is a node of the remote station, to the main station to send substation internal equipment monitoring and diagnosis system and its own state information.
