This paper presents the results of a simulation study on a 12-pulse HVDC (High Voltage Direct Current) using a system in Simulink, specialized Toolbox in Matlab for simulating control systems. The object of the study was to investigate the steady state and dynamic performance of the system. First, response of current regulator after change in current reference is examined in order to see the behaviour of the controllers in controlling the desired current. Next, the digital simulation of a test system is presented and the response to a DC fault in the line and the AC fault at inverter side is shown. The results are evaluated to enhance the recovery of the system from the disturbances and voltage dependent current limits (VDCOL) for a full range of typical system disturbances. The presented approach benefits from Simulink's advantages in modeling and simulating dynamical systems. The simulation results are compared with other studies using EMTP (Electromagnetic Transient Program) and EMTDC (Electromagnetic Transient Program DC Analysis).
