Create simulation models using Computational Fluid Dynamics (CFD) or similar to illustrate how the wake effect from wind turbines interacts with overhead line structures, conductors and components. In order to highlight specific spans of conductor that are at risk of increased vibration due to the installation of wind turbines, the following project stages are envisaged; Measure conductor vibration and environmental conditions of existing transmission overhead line conductors before and after the installation of wind turbines.Using Computational Fluid Dynamics (CFD) or similar develop models illustrating how wake effect from wind turbines interacts with overhead line structures, conductors and components.Apply the results of the on-site conductor vibration and environmental monitoring data to the models to create an accurate representation of the wake effect of the wind turbines. Use the models to explore if the wind turbine is inducing adverse vibrations and if so the likely impact on the existing overhead line conductor or associated assets. The projects objectives are as follows;To accurately model and understand the potential impact, due to wake induced vibration from wind turbine installations erected in proximity to existing transmission overhead line conductors Provide guidance for future proposed installations of wind turbines in proximity to transmission overhead lines.

SSEN continues to encourage the development of generation capability within its network. However, as a consequence of the growth, it is inevitable that some wind generation schemes may encroach or come close to existing on-shore infrastructure such as Transmission Overhead Lines. The question being posed is “what effect and at what proximity do wind generators introduce an undesirable effect on existing conductor configurations (single, twin, quad) and conductor types (ACSR, ACCC, HTLS and both round or trapezoidal) used on transmission overhead lines, specifically accelerated deterioration and ageing from wake induced vibration.The Wake Induced Vibration Modelling will enable a means to consider the effects of this phenomena on the conductors of overhead line networks prior to the installation and construction of wind turbines or other wake induced systems.
