Methodology for the energetic characterisation of rain erosion on wind turbine blades using meteorological data: A case study for The Netherlands

Rain erosion on the leading edge of wind turbine blades is an intricate engineering challenge for industry. Based energetic approach, this work proposes a methodology to characterise capacity raindrop impacts onto blades. This can be used with meteorological data from public institutions or direct measurements at locations. The characterisation analysed using accumulative and per impact erosive variables, that is, total kinetic energy impact. To consider frequency impacts, two variables are proposed, namely, power These calculated Royal Netherlands Meteorological Institute (Koninklijk Nederlands Meteorologisch Instituut, KNMI) last 25 years jointly operation specifications actual model (Suzlon S111). main contribution was found speed because it controls rotational velocity turbine. Also, intensity rainfall logging, temporal resolution data, play significant role.
