To achieve high-precision synchronous measurement of time-domain waveforms in different scenarios, this paper uses the advantages of 5G communication technology such as large bandwidth, low latency, and high-precision synchronization to propose the real-time acquisition of synchronous waveforms and remote power quality monitoring technology using GPS and Beidou dual timing. This article first analyzes the causes of GPS and Beidou timing errors. Secondly, the architecture and hardware design of a synchronous waveform collection terminal using 5G modules, GPS, and Beidou modules are proposed. Finally, an on-site installation test was conducted on the terminal designed in this article to verify the synchronization accuracy and power quality monitoring performance. Experimental results show that the terminal designed in this article can realize the functions of synchronous waveform collection and real-time monitoring of power quality.
