Recently, a parametric average-value model (PAVM) has been presented for diode rectifiers with internal faults, which considers their asymmetrical operation by including the ac-side harmonics in both positive and negative sequences. In this letter, the PAVM methodology is extended and generalized for thyristor-controlled rectifiers with faults. The presented PAVM considers the firing angle of thyristors in its formulation. Using extensive computer studies, the proposed PAVM is verified to reconstruct the detailed model results even under dynamics of thyristor firing angle control under faulty conditions, while providing faster and more efficient simulations compared with the detailed model.
