“…In the studies of reducing fluctuations and amplitudes of the aerodynamic load, the pitch control technology for fixed wind turbines is no longer fully applicable. So Sang et al [42] proposed a new cycle pitch control mechanism. In this study, the cyclic pitch was achieved by a swash plate which could tilt a certain controllable angle.…”

“…No obstante, sí afecta el coeficiente de torque y la distribución de presiones, debido a que cuando las aspas están en la región aguas arriba, la diferencia de presión entre las caras del aspa es máxima para un ángulo de pitch de 6°, ángulo en el cual también es posible alcanzar el máximo coeficiente de torque [45]. En el mismo ámbito, se demostró con una balanza de seis ejes que, para una turbina eólica flotante fuera de la costa con flujo diagonal, la amplitud de la variación en un sistema cíclico para control del pitch, no afecta el coeficiente de potencia ni el coeficiente de empuje [46]. En la figura 2 se muestra un esquema del túnel.…”

Se presenta una revisión de literatura de los túneles de viento con mayor relevancia en la investigación sobre energía eólica. Se realizó una búsqueda sistemática en la base de datos de Web of Science (WoS) en la que se obtuvieron 93 artículos que fueron filtrados para el periodo 2016-2020 y mediante distintos criterios de relevancia. Los artículos permitieron identificar 34 túneles alrededor del mundo. Se seleccionaron los ocho túneles de viento con mayor volumen de publicación y se presentan los estudios realizados en estos. Los principales temas encontrados en la revisión tratan sobre turbinas de eje horizontal y vertical, estelas, perfiles aerodinámicos y recurso eólico. Esta revisión tiene como objetivo servir de referencia para los investigadores en energía eólica que requieren realizar experimentos en túneles de viento.

“…In order to obtain a clearer understanding of pitch load, Dai et al established the theoretical analysis model of the pitch load [8,9], Yang et al studied the load prediction of the MEXICO rotor [10], Sang et al [11] performed an experiment to investigate the effect of the diagonal inflow on the aerodynamic forces. For improving the blade structure design, Lee et al optimized the blade pitch angle based on the BEM theory [12], Pavese and Verelst et al reduced the flapping moment and the ultimate load of the blade [13,14].…”

Pitch control is a basic function of large-scale wind turbines to improve energy capture efficiency. Pitch system is also a component system with a high failure rate due to the complex pitch behaviour. It is helpful to the practical design and control if a clear pitch behaviour is obtained. However, pitch behaviour is affected by the structure of wind turbines, control strategies, wind resource characteristics, and so on. So, there is still a lack of sufficient understanding. In this study, the pitch behaviour of a 2 MW wind turbine is investigated based on SCADA data. Four key evaluation indicators describing pitch behaviour are proposed, which include pitch status, pitch time consumption, pitch angle peak, and mean pitch angle. Moreover, the SCADA data extraction algorithm for pitch behaviour investigation is also given. Then, the pitch behaviour is investigated based on statistical evaluation. Some valuable conclusions have been given. For example, for the investigated wind turbine, the time proportions for the four states (non-pitch, increasing pitch, pausing pitch, and decreasing pitch) are 85.80%, 5.97%, 1.45%, and 6.78%, respectively. The pitch cycles, pitch angle peak, and mean pitch angle increase with the increase of the standard deviation of wind speed.This is an open access article under the terms of the Creative Commons Attribution License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited.
