Abstract

In this study, the results of several accuracy verifications of Scanning LiDAR(SL) measurements, which are increasingly used for offshore wind observation, were studied. The simulated effect of measuring multiple Virtual Met Masts(VMMs) using Dual SL(DSL) was also explored. Single SL(SSL) was found to have suitable accuracy on average although some sites performed worse than others. Next, when verifying DSL accuracy, it was confirmed that the observation results satisfied the KPI described in the NEDO Guidebook(New Energy and Industrial Technology Development Organization, a national research and development agency, published an interim report of their Offshore Wind Observation Guidebook, Various recommendations of how to use and verify the accuracy of SSL and DSL are included). Therefore, it was confirmed that the DSL in this case can be considered as having the same accuracy as a cup anemometer. Finally, when the accuracy of measuring multiple VMMs using DSL was studied, it was found that when measuring up to 4 VMMs, the results cleared the KPIs described in the NEDO Guidebook. This means that even when multiple VMMs are being measured by DSL, the average wind speed can be measured with almost the same accuracy as a cup anemometer. This prevents the need for multiple pairs of DSLs being used to measure a number of different locations.
