PD IEC TR 61400-12-4, which is a Technical Report, summarizes the current state-of-the-art in numerical flow modelling, existing guidelines, and benchmarking experiences in numerical model validation and verification.
PD IEC TR 61400-12-4 discusses key technical issues about the use of model validation and verification for wind applications and identifies existing open issues including recommendations for further validation through benchmarking.
PD IEC TR 61400-12-4 on Wind energy generation systems is useful for:
Manufacturers and suppliers of wind turbine blades
A wind turbine turns wind energy into electricity using the aerodynamic force from the rotor blades, which work like an airplane wing or helicopter rotor blade.
PD IEC TR 61400-12-4 provides a practical guide for predicting the design wind loads on a building, including the effect of terrain using CFD. According to this guideline, CFD can be used as an alternative to a wind tunnel test.
PD IEC TR 61400-12-4 describes how to calculate the SC results and also when the results are considered valid for power performance testing purposes.
The purpose of PD IEC TR 61400-12-4 is to propose methods to quantify the uncertainty of the modelling assumptions.
Overall, PD IEC TR 61400-12-4 describes methods for numerical site calibration for power performance testing of wind turbines for wind energy generation systems and analyses site calibration results, benchmarking the numerical model validation and verifying the results which help in manufacturing powerful and effective wind turbines to convert kinetic energy into electrical energy.
