Research And Design Of The Campus Electricity Management System

Low voltage power line carrier meter reading technology, it means usinglow-voltage power line as communication media for power data transmission andinformation exchange. The thesis has designed an Energy-saving power managementsystem based on the technology that has combined to the special environment ofschool such as School buildings, cafeteria and supermarkets. The application ofcampus LAN in meter reading system to achieve data transmission following to thecollection is a less technology application currently. Its advantage is Low investmentcost and it can meet the transmission requirements at the same time. Power predictionis the premise of the overall planning about load and it can provide based data forEnergy-optimized.In this thesis, the load is classified reasonably in view of the shortcomings ofLow voltage distribution network such as complex structure, multi-branch lines,complex nature of the load and incomplete historical data with the background ofcampus energy monitoring project. Power management net is designed and powermanagement devices are installed in view of Campus-specific distribution network.Collection terminals and network are tested in the process of installing devices.Corresponding solution is proposed in view of the problems produced in the processof devices operation.Feasibility suggestions are put forward after the data come from the managementwhich is analysed and processed and the line loss is obtained according to thecampus transformer equipment parameters and circuit parameters. Short term prediction is obtained by BP neural network and the long one is obtained by Greymodel on the basis of system data and Historical data. The power management canprovide reliable reference for the rectification of campus building and the renovationof line and provide reliable data for campus electricity management.
