Abstract

Wind farm electrical system design presents some unique grounding considerations that are not always associated with other types of electrical power systems. The three major grounding design areas include the wind turbine generators, the collector cable system, and the utility interconnect substation. These design considerations include system grounding, equipment grounding and bonding, and the interface with lightning protection systems.
