Analysis of current characteristics of outage generator for microgrid in outage mode operation

This paper describes the current characteristics of outage generator for microgrid in outage mode operation. The outage can be generated with 3-phase voltage disturbance generator. The STS current becomes very huge during the first cycle of the outage, and the magnitude of the current depends on the time impedance, series transformer leakage inductance, interfacing reactor of PCS, and the maximum allowable PCS output current. The current and load voltage waveform are analysed through simulation.
