Dynamic performance of an hvdc link

الملخص EN

This paper presents the results of a simulation study on a 12 pulse HVDC (High Voltage Direct Current) using a system in Matlab / Simulink.

The object of the study is to investigate the steady state and dynamic performance of the system.

First we examine response of current regulator after change in current reference in order to see the behavior of the controllers in controlling the desired current.

Next, we present the digital simulation of a test system and show the response to a DC fault in the line and the AC fault at inverter side.

The results are evaluated to enhance the recovery of the system from the disturbances for a full range of typical disturbances.

The presented approach benefits from Simulink’s advantages in modeling and simulating dynamical systems.
