About 250 MW wind farms will be installed in Jeju power system in the near future. The capacity of wind farms corresponds to more than 35% of total power generation capacity of Jeju power system with a 150MW high voltage direct current transmission (HVDC) system. Power quality analysis is needed in this case because dispersed systems take charge of a large portion of total power generation. This paper investigates a power quality prediction of Jeju power system with newly installed wind farms. A modeled Jeju power system including power plants, transmission lines, wind farms, and the HVDC transmission system is analyzed by a real time digital simulator. The simulation results show the frequency variation during HVDC overhaul and general period. The power quality of Jeju power system is predicted by simulation results.
