碩士 / 國立臺灣大學 / 工業工程學研究所 / 107 / Renewable energy has gradually played an important role in international electricity market. In Taiwan, the offshore wind turbines are expected to reach an installed capacity of 5.5 GW by 2025. Aside from the infrastructure during their installation, the maintenance of offshore wind turbines afterwards is also a key factor to guarantee the normal operation of those turbines. Maintenance equipment is therefore needed, but it may fail when in need. Equipment failure results in waiting time and its associated cost called waiting cost. How they affect the maintenance of wind turbines is investigated in this thesis. The analysis is based primarily on queuing theory and concepts of reliability engineering. In the queuing model, the input value is finite, and the decision-making parameters are failure rate and repair rate of the offshore wind turbines. A set of decision-making parameters that results in the shortest waiting time in average can be found based on the model. The waiting cost can be obtained accordingly. To test the model, data of 12 offshore wind farms in Taiwan were collected. A few assumptions were made to supplement the data. It is found through analysis that equipment failure has a significant impact on the maintenance cost of all kinds of wind farms. Therefore, it should be taken into consideration during the operation and maintenance of a wind farm.
