Assessment and Certification of Wind Farm in Aschersleben

  • For a wind farm in Aschersleben, Germany, Energiequelle GmbH required independent verification of the electrical characteristics in compliance with the German grid code for high voltage connection levels. That is why FGH, a cooperation partner of TÜV Rheinland, was the right choice for the project, due to its expertise in grid code compliance testing and integration of dispersed power generation units into power grids.

    Initial situation and requirements

    Energiequelle GmbH is an operating company that plans and erects wind farms, biogas plants, photovoltaic plants and electrical distribution substations in Germany and Europe. The company is also engaged in grid connection services for private and public power grids. Since the adoption of the German System Service Ordinance by Wind Energy Plants in 2009 it has become mandatory that wind turbines and wind farms connected to the German medium or high voltage system fulfill the advanced requirements of the corresponding grid codes. An independent and accredited third-party is required by law to verify compliance and provide certification.

    Solutions, results

    The main service provided in the project was verification of fulfillment of German grid code requirements as they apply to wind power plants connected to the high voltage transmission grid. The assessment of the wind farm’s characteristics principally involved load flow calculations resulting from simulations and dynamic stability analyses.

    FGH carried out an assessment of the switching conditions, the protection devices and the system behavior of the plant under fault conditions. Further evaluation work involved determination of the current rating of power equipment and production facilities as well as the requirements for the construction and structure. The reactive power capability, system perturbations and active power reduction, including power management were also checked and all requirements were fulfilled.

    Did you know

    The wind farm in Aschersleben consists of 10 Enercon E-70/ E4 2.0 MW turbines with an installed capacity of 20 MW. The corresponding unit certificates for these wind turbines were issued by FGH as well.
