Research On Terminal Fusion Of Marketing And Power Distribution Transformer Based On Broadband Carrier Technology

The construction of the electricity information collection system of the State Grid Corporation has been fully completed from 2010 to 2017.According to statistics,70% local communication mode of the electricity information collection system uses narrowband carrier communication technology.After years of operation and maintenance by various provincial power companies,the inherent technical bottleneck of narrow-band carrier communication methods has hindered the promotion and application of power consumption information collection systems.Therefore,the exploration of the practical application of broadband carrier communication technology has become a new hot topic to solve the bottleneck of local communication technology.Firstly,this paper analyzes the structure of the electricity information acquisition system,the characteristics of the low-voltage power line carrier channel,and the basic principle of the broadband carrier technology.It is judged by analyzing the disadvantages such as the noise interference generated by a large number of frequency conversion equipment in the low-voltage power line and the signal attenuation caused by the long supply radius.The power line communication channel has strong frequency selectivity,and the comparison result of the broadband power line carrier communication mode with other local channel communication methods proves that it has strong technical advantages.Secondly,through the testing and comparison of the technical indicators of local communication acquisition methods such as narrow-band carrier communication,micro-power wireless communication and broadband carrier communication,and deepening the application function requirements,the broadband carrier communication technology ratio is verified.The advantages of narrow-band carrier communication and micro-power wireless communication technology,which can fully meet the requirements of deepening application functions of power information data collection,have the characteristics of high efficiency and stability,and ensure the real-time performance of remote fee-control functions and various curves.The integrity of data collection,which provides an effective application basis for the pilot project of the subsequent broadband carrier technology.Finally,the design principles,technical principles,functional specifications of the broadband carrier module,real-time monitoring of specific implementation,big data processing,communication and other power information collection systems are deeply studied.The power consumption information collection system based on broadband carrier technology provides the means of marketing and transportation inspection big data collectionand analysis without changing the existing acquisition architecture,providing data support for the end of the area integration,and can meet the national grid.The company’s grassroots units are engaged in the urgent need for professionals to use electricity information for power users.
