In this paper, two standard VSC HVDC dynamic models are proposed. The full system model, consisting of the converter and its controllers, DC circuit equations, and coupling equations, is derived mathematically. Special attention is given to the filter and phase-locked loop (PLL), often neglected in VSC HVC modelling. A reduced order model is then derived from the full model by neglecting the smallest time constants, resulting in a reduced set of differential equations that can be integrated with a larger time step. The models are implemented in MatDyn, a Matlab based stability program. Simulations validate the proposed models.
