V. Algorithm Demonstration Software by Matlab GUI

An algorithm demonstration software has been developed by Matlab GUI. The program processes the power quality waveforms and classifies them to different types of events. The window size we take is 5 cycle. The following screen snapshots show some functionalities of this program.

Open the data file. (Data file can be generated by another Matlab function.)





Correct recognition of the voltage sag event.





Correct recognition of the high frequency capacitor switching event.





Click the "FFT" button to view the spectrum of the current event.





View the classification record by clicking the "Record" button.
