Intelligent electric meter load identification performance evaluation device

The invention provides an intelligent electric meter load identification performance evaluation device which comprises a control unit, a waveform playback unit and a serial server; the control unit is responsible for case issuing, report generation and identification result interrogation; the control unit selects cases from the constructed multi-scene graded typical case library according to test requirements, controls the waveform playback unit to output voltage and current waveforms through an Ethernet port, and reproduces load waveforms in diversified real power utilization scenes; the waveform playback unit outputs voltage and current test signals required by the test; the tested new-generation intelligent electric meter is connected with the input end of the serial port server through a 485 serial port; the device can accurately reproduce the load waveform in a diversified real power utilization scene, achieves the batch detection of the non-intrusive load identification capability of a new-generation in
