단지 접근성 및 대형 부품의 신뢰성 향상에 따른 해상풍력단지 O&M 성능 비교

In the renewable energy field, wind energy has grown the most over the past decade. Many wind farms are being developed offshore to overcome the limitations of onshore wind farms and to utilize strong and steady wind resources. However, the initial investment costs for offshore farms are larger than for onshore ones, and the costs of operation and maintenance may be substantially higher imited maintenance and accessibility to the wind turbines due to weather. Maintenance strategy and planning optimization can significantly reduce operating costs. This process is important for offshore wind farms to reduce the high economic risks associated with uncertainties about the accessibility and reliability of wind turbine systems. In this study, O&M performance was compared with a case study in which different maintenance strategies were reflected. We investigated the advantages of reducing the distance between the O&M port and the wind farm and applying a condition-based maintenance strategy for the large components of wind turbines. As a result, it is possible to improve the availability of wind turbines and reduce maintenance costs by improving accessibility to the farm and the reliability of large parts.
