Asymmetrical Fault Ride-Through Control Strategy for Rotor-Side Converter of DFIG
IEEE transactions on energy conversion, 2020This article proposes an asymmetrical fault ride-through (FRT) control strategy for the rotor-side converter (RSC) of a doubly fed induction generator (DFIG).

Induction Machine Emulation under Asymmetric Grid Faults
2020 IEEE Energy Conversion Congress and Exposition (ECCE), 2020Machine emulation is the concept of developing a virtual machine in real time with power-hardware-in-the-loop (PHIL) technology. This process of emulation allows testing the variable speed drive or drive inverter or the performance of grid without using a real machine.

Although it is commonly assumed that power swing is symmetrical and will have identical effects on all three-phase voltages and currents, there is another type of power swing, which is asymmetrical and mainly occurs during single-pole tripping (SPT), the

Fast generator protection against internal asymmetrical faults
IEEE Transactions on Power Apparatus and Systems, 1977An on-line digital computer technique for the protection of a generator against internal asymmetrical faults is described in this paper. The proposed technique relies on the detection of a second harmonic component in the field current at the onset of a fault in the armature winding.

Grid-forming (GFM) controls exhibit robust frequency and voltage support capabilities for inverter-based resources (IBRs). This also shows promise for doubly fed induction generator-based wind turbine generators (DFIG-based WTGs).

Grid-connected converters must remain coupled to the grid during a fault. They have to control the reactive currents injected to the grid because of its limited overload capacity. In particular, grid-forming (GFM) converters ride through the fault either

Asymmetrical fault analysis using the bus impedance matrix
Proceedings of the Institution of Electrical Engineers, 1978The method of the busbar impedance matrix is applied to the solution of asymmetrical faults through the use of sequence impedances and Kron's constraint matrix. An algorithm is proposed to facilitate the routine solution of complex configurations including simultaneous and cross-country faults.
