Analysis of oscillation modes in a VSC-HVDC system
2015 5th International Conference on Electric Utility Deregulation and Restructuring and Power Technologies (DRPT), 2015Harmonic instability may occur when a controlled voltage source converter interacts with the local power grid in a power system. In this paper, oscillation modes are analyzed in a voltage source converter based high voltage direct current (VSC-HVDC) system.

Fault Current Limiters for VSC-HVDC systems
10th IET International Conference on AC and DC Power Transmission (ACDC 2012), 2012Fault 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.
