Research on state perception data acquisition technology for PV modules based on dual-mode communication technology

Abstract

A photovoltaic (PV) module state perception data acquisition technology based on high-speed carrier and high-speed micropower wireless dual-mode communication technology (DMCT) networking is proposed, which realizes real-time perception of the operating status of distributed PV DC side modules by the electric energy data acquisition system (EEDAS), effectively solving the problem of fine monitoring and control of PV modules. The experimental results show that the one-time acquisition success rate of PV module status sensing data is more than 90%, and the minute-level acquisition success rate is more than 99%, which meets the communication reliability and timeliness requirements of EEDAS for low-voltage distributed PV acquisition and monitoring.
