This paper presents the modeling and analysis of Hankyung wind farm connected with 3MW DFIG and 1.5MW opti-slip type wind turbine system. For the computer simulation, three kinds of main items are modeled, which are 21MW wind farm, power transformer, transmission line and power load.
To analyze the charactreistics of output of the wind power generation to the Jeju power system, two kinds of simulations are carried out by using the PSCAD/EMTDC program. One is the steady

state operation under the variable speed wind, and the other is one T/L line ground fault when all of wind farms in Hankyung operated steady state under the rated power output.
With the comparison of these results, it is useful for analyzing the characteristics of power system versus wind power generation according to variable speed wind.
