What is BS EN 61400-13 - Measurement of mechanical load in wind turbines about?
BS EN 61400-13 discusses wind turbines with a focus on the measurement of mechanical loads.
BS EN 61400-13 is the 13 th part of the BS EN 61400 multi-series on wind turbines that describes the measurement of fundamental structural loads on wind turbines for the purpose of the load simulation model validation.
BS EN 61400-13 prescribes the requirements and recommendations for site selection, signal selection, data acquisition, calibration, data verification, measurement load cases, capture matrix, post-processing, uncertainty determination, and reporting. Informative annexes are also provided to improve understanding of testing methods.
The methods described in BS EN 61400-13 are used for mechanical loads measurements for other purposes such as obtaining a measured statistical representation of loads, direct measurements of the design loads, safety and function testing, or measurement of component loads. If these methods are used for an alternative objective or used for an unconventional wind turbine design, the required signals, measurement load cases, capture matrix, and post processing methods should be evaluated and if needed adjusted to fit the objective.
