Research on Power Line Carrier Communication Chip Compatible with Multi-standard

In China, the traditional single carrier mode has been unable to meet the increasingly high requirements of real-time data acquisition in power system due to its slow communication speed, small channel capacity, low success rate of reading and engineering maintenance. Broadband power line carrier technology based on HPLC can break through the transmission bottleneck of current communication channel, Good communication ability can realize massive power consumption information collection data and full-time real-time transmission. Through station area identification, phase identification and other related characteristics, various file information can be easily obtained, and big data analysis is possible with various information sources. Since 2016, it has gradually replaced the original narrowband power line carrier technology and become the most important communication mode of smart meters.
