Transient, Temporary and Ground Fault Overvoltages at Wind Farm Installations
Wind farms by the nature of their design and operating characteristics are susceptible to a variety of overvoltages. Hence it is always important to conduct studies and tests of the various levels of overvoltages and how the equipment at the wind farm are able to withstand with or without mitigation measures. In this Blog, we will provide an overview of the issues, the analytical approach and potential mitigation. Then, we demonstrate how these are applied to a sample wind farm.
Transient Overvoltages in Wind Farms, and a Case Study
In various Blogs on this site, we have talked about unique technical issues associated with integrating wind farms into existing grids. This Blog now addresses the matter of transient overvoltages, or TOV, specifically with respect to potential risks to customers and any required mitigation associated with wind farms installations.
