부유식 해상풍력 유지보수 관리 적용을 위한 발전손실량 특성 분석
문성빈,안송강,성원경,오영진 한국풍력에너지학회 2022 풍력에너지저널 Vol.13 No.1
Currently, the Korean government is driving the construction of large-scale floating offshore wind farms to increase domestic renewable energy generation and decrease carbon emissions. In offshore wind farms, maintenance approaches can be limited more often than onshore wind farms by marine weather conditions (wave height, etc.). Therefore, maintenance planning optimization is more important to minimize maintenance costs and power generation loss by downtime. Additionally, the power generation of a wind farm is affected by wind speed as well as wind direction because of the wake effect, so it is possible that power generation loss by downtime is also dependent on combinations of weather conditions (wind speed and direction) and the location of wind turbines for maintenance. In this study, the effects of the wind conditions and the locations of tripped wind turbines on power generation loss were explored for a hypothetical floating offshore wind farm. In order to calculate the power generation of a wind farm, a wake effect calculator was developed based on Jensen’s formula. Then, a simple methodology of determining maintenance priorities that minimize power generation loss was proposed.

BIM을 활용한 증강현실 기반 지하시설물 관리 시스템 개발에 관한 연구
신재섭,안송강,송정욱 사단법인 한국터널지하공간학회 2022 한국터널지하공간학회논문집 Vol.24 No.6
In Korea, safety accidents are continuously occurring due to the aging of underground facilities and lack of systematic management. Moreover, although the underground space is continuously being developed, the current status information is not clearly recorded and managed, so there is a limit to the systematic management of underground facilities. Therefore, this study developed an augmented reality-based system that can effectively maintain and manage underground facilities that are difficult to manage because they are located underground. In order to develop an augmented reality-based underground facility management system, three essential requirements, ‘precise localization’, ‘use of BIM information’, and ‘ensure usability’ were derived and reflected in the system. By utilizing Broadcast-RTK, the positional precision was secured to cm level, and the configuration and attribute information of the BIM was converted into the IFC format to construct a system that could be implemented in augmented reality. It developed an application that can optimize usability. Finally, through simulation, the configuration and attribute information of structures and mechanical systems constituting underground facilities were implemented in augmented reality. In addition, it was confirmed that the accurate and highly consistent augmented reality system works even in harsh environment (near high-rise building). 우리나라에서는 지하시설물의 노후화와 체계적인 관리 부족으로 인한 안전사고가 지속적으로 발생하고 있다. 하지만 지하공간이 지속적으로 개발되고 있음에도 지하시설물의 관리 주체가 다양하고 이에 대한 현황정보가 명확하게 기록 ‧ 관리되고 있지 않아, 체계적인 지하시설물 관리에 한계가 있는 상황이다. 따라서 본 연구는 지하에 위치해 확인하기 어려운지하시설물을 증강현실로 구현하여 유지관리 과정에서 효과적으로 사용할 수 있는 시스템을 개발하였다. 증강현실기반지하시설물 관리 시스템 개발을 위해 세 가지 필수 요구사항인 ‘정밀 위치파악’, ‘BIM 설계정보 활용’, ‘사용성 확보’를도출하여 이를 시스템 개발에 반영하였다. Broadcast-RTK를 활용하여 위치정밀도를 cm급으로 확보하였고, BIM 모델의 형상 및 속성정보를 IFC포맷으로 변환하여 증강현실로 구현하는 시스템을 구성하였다. 또한 사용성을 최적화할 수있는 Application을 개발하였다. 마지막으로, 시뮬레이션을 통해 지하시설물을 구성하는 구조체 및 기계 시스템의 형상,속성정보를 증강현실로 구현하였다. 또한 가혹한 환경(고층 빌딩 인접)에서도 정밀하고 정합성 높은 증강현실 시스템이작동함을 확인할 수 있었다.

Operations and maintenance (O&M) in offshore wind farms accounts for a substantial portion of the life cycle cost due to harsh weather conditions and vessel dispatching. In this regard, it is crucial to expedite O&M technologies in South Korea, which is in the early stage of harnessing wind resources from the ocean. This contribution investigates an O&M planning and scheduling model for floating offshore wind farms with a literature review and use case study. We introduce the development of a long- and short-term maintenance planning framework as part of an integrated O&M platform. This contains a single vessel and fleets routing composition along with technicians and a maintenance job list based on numerical algorithms. Additionally, the routing search presents the basis of decision support for economic trade-offs regarding smooth operation corresponding to ever-changing wind farm situations. The maintenance planning simulator will ultimately contribute to support yearly and day-to-day power-related decisions in a cost-effective manner.
