Overhead Lines and Electricity Transmission Networks
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.
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.
