Abstract :
Electronic Power Transformer (EPT) is capable of improving power quality without additional devices; hence it has the potential of pervasive application in prospective utility grid. Ahead of field test, transient analysis of EPT is necessary to verify power supply reliability as well as ensure safety. In this paper, the Electro-Magnetic Transient (EMT) simulation model of an industrial prototype of 10kV/400V/500kVA unidirectional EPT is built in PSCAD/EMTDC. Then the validation of the model and case studies under fault conditions are carried out. Simulation results show that the prototype can withstand phase-to-phase and phase-to-ground faults and sustain regular output after timely adjustment.
