“…Decisions relating to the use, or not, of a gearbox in the wind turbine largely come down to financial factors and trade-offs between capital cost, weight, reliability, maintainability and the OEM's (original equipment manufacturer) existing expertise. Historically a majority of variable speed wind turbines have used doubly fed induction generator technology with a multistage gearbox (Polinder et al, 2005). Gearboxes, however, manifest relatively high failure rates and so lost revenue due to downtimes and repairs has become a major concern of the wind energy industry (Su et al, 2017;Dabrowski and Natarajan, 2015).…”

This paper presents a review of existing theory and practice relating to main bearings for wind turbines. The main bearing performs the critical role of supporting the turbine rotor, with replacements typically requiring its complete removal. The operational conditions and loading for wind turbine main bearings deviate significantly from those of more conventional power plants and other bearings present in the wind turbine power train, i.e. those in the gearbox and generator. This work seeks to thoroughly document current main-bearing theory in order to allow for appraisal of existing design and analysis practices, while also seeking to form a solid foundation for future research in this area. The most common main-bearing setups are presented along with standards for bearing selection and rating. Typical loads generated by a wind turbine rotor, and subsequently reacted at the main bearing, are discussed. This is followed by the related tribological theories of lubrication, wear and associated failure mechanisms. Finally, existing techniques for bearing modelling, fault diagnosis and prognosis relevant to the main bearing are presented.Published by Copernicus Publications on behalf of the European Academy of Wind Energy e.V.

“…On the other hand, Yaw control the horizontal axis rotation of turbine, making sure that turbine is constantly facing into the wind, because wind speed can vary very quickly misalign the turbine from facing into wind and costing losses in output power. The final type of control is done through electrical subsystems in which dynamic control of turbine is achieved by electronic converters which are connected at the terminal of generator [57]. All the different parameter of the system is taken to data acquisition for measuring and analysis purpose.…”

Recent decades have seen an incline in integration of wind energy in to power systems across the world. This invariably leads to lower share of conventional power plant which subsequently reduces the grid's inertia as a consequence of the decoupling rotational mass of the variable speed turbines and grid through power electronic converters. Accordingly, the overall system inertia is lowered leading to more frequent and intense frequency variations concomitant with the variation in the load. This research focuses on alleviating the rotational mass and inertia related problems caused by increasing wind power integration by adding an inertial loop to compensate the impact of frequency deviations due to abnormal transient conditions. The virtual inertia, thus added, reduces maximum rotational speed deviation while at the same time making the system slower and more oscillatory. The simulation consists of addition of synchronous generator capable of adapting its power output to the fluctuations in grid loads. A load step has been added for analyzing the performance improvement of the system as a result of the virtual inertia addition. The simulation has been modeled in Simulink MATLAB. The addition of the inertial power results in the improving the frequency drop from 58.42 to 59.31 Hz. This stabilization of 0.9 Hz carries a lot of significance for improving grid stability. In addition the angular speed of the turbine has also been enhanced as a result of the virtual inertia. These findings will prove extremely helpful in offsetting the drawbacks of greater wind energy addition to grid. The analysis needs to be further replicated with other transient conditions before being implemented in the grid.

“…The second was to use that model to determine analytically the number and the value of the resonance frequencies from the generator angular velocity in such a way that such information could be used by any control algorithm or even by the mechatronic system designers. We assessed through experimental validation using a real 100 kW wind turbine that these two objectives were reached, demonstrating that the different vibration modes were detected using only the generator angular velocity.The main objective of wind turbines is to extract the maximum amount of energy from wind [2,3], taking into account both the environmental [4] and economic effects [1,5], and avoiding resonances in the tower and the rest of the structure [6,7]. Mechanical fatigue can cause wear of elements of the nacelle and the tower, which in turn can cause resonances with the consequent breakage of elements, losing power performance and decreasing safety [8].…”

Mechatronic Modeling and Frequency Analysis of the Drive Train of a Horizontal Wind Turbine

The relevance of renewable energies is undeniable, and among them, the importance of wind energy is capital. A lot of literature has been devoted to the control techniques that deal with the optimization of the energy produced, but the maintainability of the individual wind turbines and of the farms in general is also a fundamental factor to take into account. In this paper, the authors address the general problem of knowing in advance the resonance frequencies of the power system of a wind turbine, with the underlying idea being that those frequencies should be avoided and that resonances do not occur only due to mechanical phenomena, but also because of electrical phenomena that in turn are influenced by control and optimization techniques. Therefore, the availability of that information embedded in the optimization techniques that control a wind turbine is of major importance. The main purpose of this paper was accomplished through two related objectives: the first was to obtain a mechatronic model (using a lumped parameters model of two degrees of freedom) of the drive train in the Laplace domain oriented to subsequently perform the described analysis. The second was to use that model to determine analytically the number and the value of the resonance frequencies from the generator angular velocity in such a way that such information could be used by any control algorithm or even by the mechatronic system designers. We assessed through experimental validation using a real 100 kW wind turbine that these two objectives were reached, demonstrating that the different vibration modes were detected using only the generator angular velocity.
