Research And Application Of Daqing Electric Power Information Acquisition System

Through the collection and analysis of power user's power consumption data,the power consumption information collection system realizes the online monitoring of metering device and the real-time collection of user's load,electricity,voltage and other important information,provides basic data for relevant systems in a timely,complete and accurate manner,supports the analysis and decision-making of each link of power grid enterprise's operation and management,and provides information for the realization of intelligent two-way interactive service Basis of breath.With the development of smart grid and the comprehensive construction of power consumption information collection system,higher requirements and challenges are put forward for the deepening application of power consumption information collection system of Daqing power supply company.Based on the actual application of Daqing power consumption information acquisition system in Daqing power supply company,combined with the current acquisition situation of Daqing power supply company,this paper analyzes the main problems of the system,and proposes to use the low-voltage power line broadband carrier to solve the problems of the local channel from the technical point of view.According to the characteristics of the low-voltage power line,this paper analyzes and models the system,aiming at the original broadband carrier OFDM Through in-depth analysis of the theory and key technologies,the broadband carrier replacement and comprehensive test are carried out in key stations.The test results show that the replacement of broadband carrier module makes the data transmission faster,more data collection content,more stable data transmission,solves the problem of low collection success rate of Daqing PowerSupply Company,and achieves remarkable results.At the same time,through relevant cases,Daqing power consumption is proved The information collection system provides strong data support for the marketing work of Daqing power supply company in the aspects of automatic meter reading,remote charge control,line loss management,anti stealing and online measurement monitoring,improves the business performance of Daqing power supply company,and proves that the application of broadband carrier technology and collection system has brought a qualitative leap to the economic benefit management of the company.
