MEASNET, the International Network for Harmonised and Recognised Measurements in Wind Energy, has released an updated issue of its guideline “Evaluation of Site-Specific Wind Conditions”.
The guideline introduces new requirements and improvements in the description of measurement campaigns, and it also covers wind resource and site assessment evaluations. It is aligned with IEC 61400 (International Electrotechnical Commission) standards, as MEASNET is liaised with ISO/IEC in several working groups. Given the increasing relevance of site assessments in terrain with non-homogeneous roughness conditions, an approach has been developed to implement these within the terrain representativeness. In addition, the requirements for the procedures and documentation of the long-term analyses are also specified in more detail, such as the presentation of bias error expressions and the trend analyses of reference data. An improved appendix is dedicated to requirements of the usage of remote sensing devices, as they are increasingly used for evaluation of site-specific wind conditions.
