Abstract:
Subtask 3 of the project 'Wind Turbine Load Measurement Instrumentation'will result in an improved knowledge of sources of uncertainties that occur
during load measurements. The various sources of uncertainties all contribute
to the uncertainty of the final results of the measurements. One of ECN's
tasks in the project was to draft a procedure that can be used to combine the
various sources of uncertainty into the overall uncertainty of the final
result. The proposed procedure is described in this report and follows the
general approach laid down in the ISO-standard for expression of uncertainty
in measurement. In situations where the ISO-standard fails to give a
practical procedure (e.g. in case of Rain Flow Counting) an alternative
procedure is described. Based on the proposed procedure some examples
concerning load measurements on wind turbine blades are elaborated in detail
