Simulation studies of JeJu AC power system modeling by using PSCAD/EMTDC

This paper represents the developments of the PSCAD/EMTDC based JEJU AC power systems and HVDC equivalent modeling. First, the background of the development and its associated technologies, such as PSCAD/EMTDC based generator, exciter and governor modeling are introduced. And then after the modeling has been established, the transient analysis and fault analysis have been done by using PSCAD in order to confirm the system´s stability. Furthermore, with the sudden load change studies, this modeling can be concerned as a base-modeling for connecting JeJu wind power generation into the JEJU AC power system in the further.
