New Inverter Fault Current Limiting Method by Considering Microgrid Control Strategy

摘要：

In this paper we present an approach for fault cunent limiting(FCL)in inverters of a Microgrid.For this purpose,which is based on the control system employed in Microgrid,we select the proper FCL technique.In this research it is represented that FCL inverter current with limited magnitude of id and iq that are used in PQ control dont have a good behavior in V-F controlled DG.Current limiting by decreasing the output voltage of DG is performed by the value of inverter reduction of the voltage that is selected by paying attention to the maximum current that is allowed through inverter,this value is two times of the rated current of inverter.
