Abstract

Due to the good wind field and wind conditions along the west coast of Taiwan this research analyzes these conditions and the wind energy yield for an offshore wind farm on the west side of the island The wind data used in the analysis is based on measurements from meteorological stations or meteorological buoy stations in the west of Taiwan The WindPRO software is used to analyze the wind field and wind conditions and also to determine the relation between the cost and annual energy yield for an offshore wind farm The WAsP Engineering software version 3 is used to calculate the 50-return-years extreme wind speeds using the gust wind speed and 10-minute-average wind speed data The results obtained in this work include the relationships among the wake effect annual energy production park efficiency and cost The reveal that the rotation angle of the whole wind farm with a certain number of turbines and a certain distance between the turbines can affect the annual energy production park efficiency and cost Further research could examine how the rotation angle and distance can be modified to maximize annual energy production and park efficiency and minimize the cost Wind turbines need to be operated safely and thus it is essential to know the extreme wind speed at the hub height of the turbines in advance However the wind data that is measured cannot be used to predict future extreme wind speeds WAsP Engineering version 3 is used to calculate the 50-return-years extreme wind speeds using the Gumbel statistical distribution The parameters presented in this work can be used to determine how strong wind turbines should be in order to withstand damage due to extreme winds
