A large-scale offshore wind farm may be designed with different configurations, which will cause different costs, efficiency and reliability. This thesis presents different possible configurations for a real offshore wind farm planning in Penghu and analyzes their advantages and disadvantages from the power system point of view. Three basic designs for a 201.6MW wind farm are identified in this study, including radial design, star design, and ring design. Additionally, the wind farm configuration with/without offshore substation is also considered. Next, various steady-state and dynamic power system analyses are implemented to evaluate the performance for different wind farm configurations by using two brands of wind turbine. These analyses include the calculation of steady-state operation voltage, transmission loss and fault current. In addition, system contingency events, wind speed variation and short circuit fault are also discussed for the impacts on system voltage and frequency. Simulation results show that ring design will have the lowest power transmission loss, but will need more fixed reactors. On the contrary, radial design will have the highest power transmission loss, but will need fewer fixed reactors.
