Abstract
Monitoring the quality of photovoltaic power generation in remote mountain areas is difficult, so this paper proposes a real-time online monitoring system to solve the problem by using AD7606 high-precision ADC chip and STM32 single-chip microcomputer. AD7606 realizes real-time acquisition and conversion of three-phase power data. STM32 performs wavelet transformation on the collected data to obtain power quality parameters. It stores the power quality parameters in the SD card and then uploads the power quality parameters to the host computer through Lora to display each power quality parameter in real time. Experiments show that the system can reliably realize on-line real-time monitoring of the power quality of photovoltaic power generation.
