Dynamic Characterization of Operational Wind Turbines using Operational Modal Analysis (bn0919)
Experimental dynamic characterization of a wind turbine, operating under variety of conditions, is a desired task as it provides useful insights that can be used for number of tasks including design optimization, validation and verification of aeroelastic and finite element codes and development of an optimal control system. However, current state of art experimental techniques are insufficient...
متن کاملApplication of operational modal analysis and blind source separation / Independent component analysis techniques to wind turbines (bn0562)
Wind turbines are complex structures and their dynamics vary significantly in operation, in comparison to that under stand still (parked) conditions. Presence of rotational loads and considerable aeroelastic effects makes it difficult to apply conventional system identification techniques to wind turbines. Operational Modal Analysis (OMA) is a technique of determining dynamic characteristics of...
متن کاملVirtual Wind Speed Sensor for Wind Turbines
A data-driven approach for development of a virtual wind-speed sensor for wind turbines is presented. The virtual wind-speed sensor is built from historical wind-farm data by data-mining algorithms. Four different data-mining algorithms are used to develop models using wind-speed data collected by anemometers of various wind turbines on a wind farm. The computational results produced by differe...
متن کاملStructural dynamics of wind turbines
Structural dynamics of wind turbines aims at assessing the integrity and reliability of the complete construction against varying external loading over the targeted life time. Since wind induced excitation is the most important, structural dynamics is closely connected to aeroelasticity. Most of structural analysis is based on modelling while tests are reserved for prototype assessment. To this...
متن کاملFrequency Domain Techniques for Operational Modal Analysis
Operational Modal Analysis, also known as Output Only Modal Analysis, has in the recent years, been used for determination of modal parameters of civil engineering structures and is now becoming widely used also for mechanical structures. The advantage of the method is that no artificial excitation needs to be applied to the structure, or force signals to be measured. In this paper, the non-par...
