Prof. Yarú Méndez of LM Windpower - Denmark

The latest edition of the norm IEC-61400-24 recommends that the wind turbine’s grounding system should be interconnected to the other wind turbine’s grounding system erected in the wind park; this is in order to reduce abnormal earth potential distribution and mitigate dangerous overvoltage. A comparison between a stand-alone wind turbine (without grounding system interconnection) and a set of interconnected wind turbines (with grounding system interconnection) is presented and analyzed during this lecture. Overvoltage and overcurrent in the form of surges may be the result of electromagnetic traveling waves caused by lightning; these effects may impose additional requirements for the reliable operation of a low voltage and medium voltage grid against surges caused by lightning strikes.

Biography:

Yarú Méndez is engaged as a principal engineer at the wind turbine blade manufacturer LM Wind Power in Denmark and as a lecturer in electrical engineering (EE) at the Universidad Simón Bolívar (USB) in Venezuela. The main focus of his professional and academic activity is power systems and renewable energy based power generation. Previously, he was Director of Engineering at the company Raycap GmbH in Germany and Research Engineer at the company General Electric Global Research (GEGR) in Germany. His primary responsibilities included renewable energy based systems (wind and solar) and their interaction to the grid with a main focus on electromagnetic transients. Concerning his education, he earned a degree in electrical engineering in power systems from the Universidad Simón Bolívar (USB), a Dr.-Ing. Degree from the University of Kassel (UNIK) in Germany, and an MBA degree from the University of Applied Sciences Munich (HM) in Germany. Currently, he holds 17 patents and has published 59 scientific publications as author and coauthor.
