Abstract:

This article presents an improved sampled-data model of a 12-pulse high-voltage direct current converter that is suited for linearized analyses of power systems using frequency domain methods. The applications of this model of converter with pure equidistant firing control and phase-locked loop control are discussed, respectively. Under small perturbations, the process of igniting is considered in detail. Therefore, the accuracy of the model is improved. The model is validated by time domain simulations in PSCAD/EMTDC. The results from the presented model, the quasi-steady model, and the former sampled-data model are compared by eigenvalue analysis and the complex torque coefficient method. The investigations show that the presented model is accurate and valuable in studying subsynchronous oscillations.
