Initial situation and requirements
ENERCON has been setting new standards in technological design for more than 25 years. With more than 18,000 wind turbines installed in over 30 countries, the company is also recognized internationally as one of the leading manufacturers of wind turbines and their components. With the adoption of the German System Service Ordinance by Wind Energy Plants in 2009 it became mandatory that wind turbines and wind farms connected to the German medium or high voltage system have to fulfill the advanced requirements of the corresponding grid codes. For the certification of whole wind farms, the wind turbines deployed must also be type tested.

Solutions, results
FGH has supported ENERCON with extensive certification services since 2004, including the new ENERCON E-126 wind turbine. This comprised field measurements followed by a detailed model validation, where the simulation results were compared with field measurements.
In addition, it was necessary to verify fulfillment of German grid code requirements that apply to wind turbines connected at medium and high voltage levels. An assessment of the wind turbine’s characteristics, including calculation and testing procedures for the verification of the grid code requirements, was based on FGW technical guidelines (TR3, TR4 and TR8).
FGH ensured that power generation, power control and the reactive power capability fulfilled the grid code requirements. Furthermore, FGH verified the dynamic plant behavior during system faults and validated the wind turbine model.
