An efficiency evaluation of radar‐based obstruction lights controlling at a wind turbine test site

Abstract

In this study, an obstruction lights controlling (OLC) system based on a Terma SCANTER 5000 radar has been installed at a test centre for large wind turbines. The objective of this study was to evaluate the efficiency of the OLC system and to improve this efficiency by introducing new technological features. Once the first assessment had been carried out, new software with improved tracking functionalities was installed to the radar. With the new software, a second assessment was made to compare the new performance to the old one. To analyse the tracks, geographic information system (GIS) tools have been used. A new MATLAB script was developed to automate the assessment as well as to gather data on the tracks. These data sets were used to improve the system performance by introducing a radar cross section (RCS)/speed filter. The outcome of the study is a filter that can be implemented on the radar system to improve the efficiency of the system and reduce the time that obstruction lights need to be on for by 62.59%, without compromising the integrity of the system.

“…A number of precautions are often taken, such as confidentiality agreements, sharing constraints and strictly classified outputs belonging to the specific departments of the companies (Tourangeau, 2018). Thousands of researchers produce results and use their company's affiliationand only that (Jørgensen, Tambo, & Xydis, 2019;Xydis & Mihet-Popa, 2017). This approach has created no-share mentalities and confidential research works that will never be shared, some of which could have been inspiring or the starting point for other researchers in some other part of the world in industry or academia (Czarnitzki, Grimpe, & Pellens, 2015).…”
