By Nordex Group recently installed the first N149/5.X turbine on the Genshagener Heide wind farm near Potsdam, Germany.
The Nordex Group launched the market segment for 5 MW turbines with this type of turbine in the spring of 2019. This month, the first N149/5.X will commence operations on time.
Following the installation of the turbine, the training for the N149/5.X form certification measurement and validation program begins.
With a wind speed of 6.4 m/s at a hub height of 105 meters, the site provides reasonable conditions for measuring the 5.7 MW turbine. In addition to the power curve, the Nordex Group will validate the sound power level and grid efficiency of the turbine on the basis of measurements reported in the field. This ensures that the turbine will be fully certified for the start of the production series in 2021, including the form certificate.
N149/5.X is a logical progression based on a stable approach to the flexible rating of N149/4.0-4.5. The turbine is designed for maximum flexibility and can be controlled in various modes within the 5 MW range, depending on site requirements and customer needs.
A new and highly efficient gearbox is being used and the electrical system of the Delta4000 series is being upgraded to achieve high power output in the 5 MW range.
To date the Nordex Group has already received orders for 800 MW for the N149/5.X since its launch last year.
