Abstract:
A fault inrush transient current restraining type virtual synchronous inverter and thereof is disclosed. The invention solves the problem that a virtual synchronous inverter will be burned due to inrush transient current in an extreme situation of a symmetrical fault occurring on the grid side by setting an information collection module for inverter output voltages and currents, a virtual synchronous inverting control module, a fault detection and synthesize module, a hysteresis comparison control module and a post fault clearing switch back grid-tie control module.

Claim (Index 5):
The fault inrush transient current restraining type virtual synchronous inverter, as recited in  claim 1 , wherein the hysteresis comparison control module phase locks a PCC voltage of the information collection module for the inverter output voltages and currents of the inverter to achieve and output phase A to the hysteresis comparison control module, a three-phase given value of current is generated with consideration of a pre-set over-current protection value; the three-phase given value is subtracted from a current value of the information collection module for the inverter output voltages and currents before passes a hysteresis comparator an output of which acts as a control signal to drive an IGBT (insulated gate bipolar transistor).
