Current limiting strategy for grid-connected inverters under asymmetrical short circuit faults
International Journal of Electrical Power & Energy Systems, 2021 Abstract Grid-connected inverter plays an essential role as an interface between energy resources and the power grid. The performance of the inverters is adversely affected by the grid disturbances such as imbalances and asymmetrical short circuit faults. Then, it is necessary to enhance the functionality of the inverter under such conditions.

IPM Synchronous Machine Drive Response to Symmetrical and Asynunetrical Short Circuit Faults [PDF]
IEEE Power Engineering Review, 2002 A closed-form solution is presented for the steady-state response of interior permanent magnet (IPM) synchronous machines to symmetrical short circuits including the effects of q-axis magnetic saturation. Machine response to single-phase asymmetrical short circuits is also investigated.
