by Mital Kanabar, Jorge Cardenas and David Menéndez, GE Digital Energy, USA

The article focuses on advancements and future trend of wind energy protection technology, and categorizes the topic in four areas, as shown in Figure 1.

Recent developments in wind turbine-generator technology with variations in power electronic converter configuration and control, high penetration of large wind farms, and various regional grid codes are imposing many challenges to traditionally applied protection practices, and questioning its effectiveness. This article presents some of the important advancements in wind turbine mechanical protections & condition monitoring, digital generator protection system, wind farm protection zones, and interconnection of wind farm into utility system. The upcoming trends with a wide area synchrophasor systems and fully integrated protection systems are illustrated with envisioned architectures.   More
