Description

Offshore Wind Power Generating Plant Inspection Assistance System The present invention relates to an inspection support system for offshore wind power generation facilities, and more specifically, to an inspection support system for offshore wind power generation facilities that utilizes a drone aircraft to support the diagnosis of the operating status of a sensing information collection element installed on a wind power generation tower. Generally, wind turbines are configured to generate electricity by utilizing the rotational force produced as blades rotate due to the wind. As devices that convert wind energy into electrical energy, these turbines are simple in structure and installation, easy to operate and manage, and capable of unmanned and automated operation; consequently, their adoption has been increasing dramatically in recent years. Recently, due to issues such as wind resource availability, aesthetics, and site constraints, there is a trend to construct large-scale offshore wind farms. Meanwhile, unlike onshore facilities, offshore wind power generation facilities have very poor accessibility, so there is a need for a method to efficiently perform inspections of the facilities. In response to this need, Korean registered patent No. 10-1302994 proposes a system for performing maintenance on offshore wind farms using a transport vehicle that moves along the seabed while carrying a robot; however, it has the disadvantage of poor maintenance workability because it requires the use of a transport vehicle that moves along the seabed.
