Nordex obtains unit certificate for N117/3000 according to VDE-AR-N 4120
16 February 2017
On 3 February 2017 the Nordex Group received the unit certificate according to VDE-AR-N 4120 (Technical requirements for the connection and operation of customer installations to the high voltage network (TCC High Voltage) for the N117/3000 turbine from FGH Zertifizierungsgesellschaft mbH in Mannheim. Presentation of the unit certificate is a prerequisite for connection to the German high-voltage grid (110 kV) and the operation of wind turbine generators as of 01 July 2017.
Being provided with the unit certificate at this early stage means that Nordex customers can now make more dependable plans for projects with the N117/3000 before the end of the TCC High Voltage transition period on 30 June 2017 thanks to the assessment of the grid connection by the external appraiser.
The unit certificate confirms that the WTG fully complies with the TCC High Voltage requirements. The N117/3000 has thus successfully and without restriction provided evidence of the behaviour required in the VDE-AR-N-4120 guidelines in the event of surges and to support voltage in the event of grid faults by providing reactive current in the pos./neg. sequence.
In addition to this, Nordex’s own wind farm controller (EZA controller) is being certified by FGH Zertifizierungsgesellschaft mbH in Mannheim. The EZA controller controls in particular the active and reactive power supply by individual Nordex wind turbine generators in line with the current requirements of the grid operator at the grid connection point.
Nordex will also shortly be receiving the unit certificates for the remaining wind turbines from the Gamma and Delta platforms as well as the component certificate for the wind farm controller.
