Abstract—The use of Voltage Source Converter based High Voltage Direct Current (VSC-HVDC) links is considered a major step in facilitating long distance power transfer and integrating renewable energy sources. The introduction of protective reactors throughout such systems can have significant impact on their stable operations. Therefore, a stability study in VSC-HVDC systems is necessary. This paper proposes a method to analytically describe a two-terminal VSC-HVDC link with respect to its eigenvalues. The results from dynamic simulations using PSCAD show that large protective reactors can result in system stability problem, and the suggestion is provided to develop a novel variable dc reactor in the summary.
