A Copula-Based Bayesian Network to Model Wave Climate Multivariate Uncertainty in the Alboran Sea

An accurate estimation of wind and wave variables is key for coastal and offshore applications. Recently, copulas have gained popularity for modelling wind and waves multivariate dependence, since accounting for the hydrodynamic relationships between them is needed to ensure reliable estimations of the required design values. In this study,...

Evaluation of Phase Imbalance Compensation for Mitigating DFIG-Series Capacitor Interaction

This paper assesses the suitability of the phase imbalance concept as an alternative approach for series compensating a transmission line, with the goal to eliminate adverse subsynchronous interactions between a DFIG and the transmission system. The performance of this concept, under a predefined degree of asymmetry, is compared with the...

AIS data analysis for the impacts of wind and current on ship behavior in straight waterways

Due to the increasing ship traffic flow in ports, maritime traffic safety has attracted much atten-tion. In addition to traffic flow, the ship safety in restricted waters is influenced by external navigational fac-tors (visibility, wind and current), encounter situations and human factors on board. In this paper, we investi-gate the effect of...

Wind-induced sound on buildings and structures

Wind flow around buildings and structures has led to annoying noise levels at several occasions, especially in cases where tonal sound was produced. The human hearing is equipped to distinguish tonal or pulsating sound from random noise patterns, causing tonal or pulsating sound to be perceived as more annoying. Tonality is often caused by the...

Dynamic modeling of a spar-type floating offshore wind turbine

The installation of floating wind farms in deeper water is encouraged by the stronger and steadier wind, the lower visibility and noise impact, the absence of road restrictions, but also the absence or shortage of shallow water. In the summer of 2009, the first large-scale floating wind turbine ”Hywind” was installed. Hywind is a spar-buoy...
