摘要：
The fault current characteristics of inverter interfaced distributed generators (IIDGs) are very different from those of traditional synchronous generator. Prior to the fault current analysis of IIDG, a control strategy for low voltage ride-through (LVRT) of IIDG is proposed to meet the grid code. Then the fault current characteristics of IIDG are analyzed based on the study of dynamic responses of the inverter under conditions of symmetric faults and asymmetric faults. Meanwhile, the analytical expressions of the fault current of IIDG are obtained. Finally, the fault current characteristics of IIDG are validated with simulation studies.
