Verification of electrical disturbance measurement data to be used for wind turbine model validation

In order to verify that a simulation model operation corresponds to the real-life system operation, the models are validated against measurement data of a real system or system component. The procedure naturally presumes that the used measurement data is accurate and correct. This paper discusses the possible problems in the data interpretation and errors concealed in the measurement data of three-phase electrical quantities. Also a check-list is suggested for the measurement data verification. The emphasis is especially on disturbance measurement data of wind turbines to be used for a wind turbine model validation. Use of erroneous data could lead into a false conclusion of a wind turbine behavior or incorrect validation of a wind turbine model. Potential problems and errors in the measurement data are illustrated through actual experiences of measurement data that initially seemed feasible but in fact contained errors. These experiences also demonstrate the usability of the presented check-list for data verification. Discovering the errors enables the correction of the data and increases the data reliability.
