A multi-interval digital metering test system based on wireless synchronization comprises a test analysis platform, a control host, sampling test terminals, a message controller, and a power acquisition terminal. By using a full-scenario wireless distributed test mode, the system is mainly used for sampling value synchronization testing, integrated power error testing, and the metering performanceanalysis of time characteristics, error characteristics and network anomaly characteristics of the multi-interval digital metering system, and can realize the system-level performance detection of amulti-interval metering device at a transformer station field. The multi-interval digital metering test system, by using the sampling test terminals, solves the system-level detection problem of the multi-interval digital metering device in a wireless mode, can detect the digital metering device under the operating condition by simulating voltage and current actual waveform and message transmission characteristic abnormal states, ensures the accuracy of multi-interval digital energy metering, and has a simple, economical, rational, practical and operable method.
