基于时间分集的交流系统多用户能量-信息一体化传输技术
Time-division-based Multi-user Energy-information Integrated AC Transmission Technology
摘要
Abstract
Power electronic converters can implement signal modulation techniques,allowing for the integration of energy information transmission by superimposing data carriers within the converter control loop.In this paper,a time-division-based transmission method is employed to achieve error-free transmission of low-data-carrier components in AC systems,reducing the bus harmonics caused by data carriers.Additionally,for scenarios involving multiple users randomly accessing the system simultaneously,this paper proposes a frequency-orthogonal multiplexing transmission method applied in AC systems,enabling multi-user random access to the system.This paper first presents the principles of energy-information integration transmission and time-division transmission algorithms.Subsequently,it establishes a converter model with data modulation and analyzes the data channel in the AC system.After that,an optimal design method for diversity transmission communication parameters is proposed.Finally,an AC microgrid experimental platform is set up to verify energy-information integration transmission among three converters.关键词
