In order to judge the power supply level and quality of power system,a power quality monitoring system based on communication interface technology is designed.The device module of the system is based on the sensor and STM32F1O3RC single chip computer to collect the quantity of electric energy measurement.The data is transmitted to the master station module through LoRa wireless communication technology.After receiving the data,the main station module uses the improved empirical Fourier decomposition method to realize power quality monitoring.The test results show that the system can obtain the voltage deviation results of different voltage levels and judge the power quality of each energy meter.
