Field test comparison, control, and modeling of the Sidney converter station

A procedure is presented for modeling a complex back-to-back DC converter station and its controls. The model is required for accurate transient stability analysis of the power system. A high-frequency model was developed, and its performance was compared to field test results. The model was modified to include only longer time effects significant for transient stability analysis. The final transient stability model was verified against both available field tests and the detailed high-frequency model. The model in conjunction with a transient stability program helps assure that the power system can be operated in a safe and prudent manner.<
