| Abstract: | Introduction Voltage sag is one of the most serious power quality problems in distribution network. At present, due to the lack of a system to locate the source of voltage sag, the problem of responsibility division and attribution has always been the difficulty in dealing with voltage sag accidents. It is an effective way to solve the problem of voltage sag traceability by monitoring and analyzing the synchronous power quality measurement data of distribution network. Method Firstly, the architecture and fusion scheme of the integration of synchronous phasor and power quality measurement were analyzed, and a method of voltage sag source tracing and location based on real-time synchronous measurement data was proposed. Then, the case design scheme of distribution network demonstration project was proposed. Finally, the application of synchronous phasor and power quality measurement integration in intelligent distribution network was summarized in this paper. Results The results of demonstration construction verify the feasibility of the proposed design scheme. Conclusion The demonstration project has accumulated engineering experience for subsequent large-scale promotion and replication. |
