Dynamic modeling of a VSC-HVDC converter

2013 48th International Universities' Power Engineering Conference (UPEC), 2013
The aim of this paper is to present a nonlinear dynamic model for Voltage Source Converter-based HVDC (VSC-HVDC) links that can be used for dynamic studies. It includes the main physical elements and is controlled by PI controllers with antiwindup. A linear control model is derived for efficient tuning of the controllers of the nonlinear dynamic model.

VSC-HVDC Control under Unbalanced Supply Conditions

2007 IEEE Power Engineering Society General Meeting, 2007
The voltage source converter based high voltage direct current (VSC-HVDC) technology has attracted much attention in recent years for its beneficial characteristics. The VSC-HVDC system is sensitive to voltage unbalance. However, voltage unbalance may occur in the three-phase power system frequently, due to unbalanced power supply, unbalanced loads and

Fault Current Limiters for VSC-HVDC systems

10th IET International Conference on AC and DC Power Transmission (ACDC 2012), 2012
Fault Current Limiters (FCL) limit fault current levels to a more manageable level, this way it becomes possible to increase the transmission ratings of an electrical system, without changing the equipment. Thus, the existing equipment is able to handle the new currents and protect properly the system.
