Abstract
Representation of high voltage direct current (HVDC) transmission links in power system stability studies requires special attention. A detailed model, while very precise, requires considerable time for modeling and calculation. Simplified models, on the other hand, do not always provide sufficiently accurate results. In this paper, simplified and detailed HVDC simulation models are described and compared. The dc system modeled is the plusmn500-kV, 3000-MW 12-pulse bipolar link between Gaopo rectifier station in Guizhou province and Zhaoqing inverter station in Guangdong province, China. NETOMAC, a powerful and flexible software package, is employed for modeling and calculations. Simulation cases based on the China Southern Power Grid data are presented and analyzed. Appropriate model selection is discussed.
