Research On 10kV Feeder Automation Communication System

At present,China's electricity information collection and distribution automation,commonly used communications technology,including optical fiber communications,wireless communications and power line carrier communications and other means.As the agricultural network structure is complex,the use of optical fiber communication,not only high investment,and construction workload,flexibility is poor,difficult to achieve in the short term.Based on the power line communication mode,we can make full use of the existing physical network of power grid,with the advantages of high network reliability,small investment and short construction period.In addition,because the power line can communicate to any measurement and control point in the power grid,it is easy to realize the information exchange between the control center and the remote terminal equipment.The flexibility of the method is strong,and it can realize the synchronous construction of the communication measurement and control technology with the grid.Compared with the use of optical fiber communication,dedicated wireless communication,compared with 10 kV power line communication,construction costs can be reduced by nearly 50%,construction and construction period will be reduced by nearly half of the time.So it is to achieve rural power network,especially in remote mountain rural power network information collection,transmission and management of one of the most effective way.10kV power line communication technology,do not need to set up special communication lines,with a small investment,short construction period,flexible and convenient,especially for rural and remote mountain routes.Taking into account the existing GPRS device,the system is compatible with GPRS communication,and can achieve automatic switching mode of communication.A variety of communication methods independent and integrated applications to meet the intelligent distribution network on the performance requirements of communication and functional requirements.The system can realize the agricultural network information collection and feeder automation functions,including the background management master station,10 kV power line communication master station,set the data terminal,10 kV intelligent switch and other equipment.Set the data terminal to complete the main station for the power users of electricity information collection,distribution transformer information collection.10 kV intelligent switch set 10 k V power line communication module,GPRS communication module,protection and control module,column switch,10 kV small power supply system and coupler in one,with communication,telemetry,remote control,remote and other functions.In short,the implementation of the system will be for the distribution network automation,information technology play an important role.
