Nordex has entered the 5MW class with a new turbine, the third model in its Delta4000 platform.
The N149/5.X can achieve a power output of 5.5MW while operating at a low sound power level, or in higher power modes where sound restrictions are not in place.
It uses the same rotor blade, doubly-fed induction generator (DFIG) and exterior nacelle dimensions as in the N149/4.0-4.5, the first model announced in the Delta4000 platform, Nordex stated.
However, the manufacturer added it scaled up the electrical system and used a new gearbox to enable the N149/5.X to achieve a higher power rating.
The turbine can be installed with a range of different tower options up to 164 metres, Nordex said. Series production of the N149/5.X is due to start in 2021.
It is aimed at core markets in Europe, and also “global growth regions” including South Africa, Australia and South America.
The model can be operated in different power modes in the 5MW range and in a range of sound power modes, Nordex added.
It can achieve a power output of 5.5MW while operating with a sound power level of 104.8dB(A), but can also be run in higher power modes at sites where emission levels are not critical, Nordex said.
The turbine can also be modified for cold climates featuring an anti-icing system for blades, enabling operation in temperatures down to -30C.
More information about the N149/5.X will be revealed at WindEurope’s European Wind Energy Conference in Bilbao, Spain next week (2-4 April).
Delta4000
Since it launched the platform in September 2017, Nordex has received orders totalling more than 700MW.
In mid-March, Nordex started series production of the turbine range at its production facility in Rostock, Germany.
The maunfacturer installed a prototype of the first Delta4000 turbine, the N149/4.0-4.5, in August 2018.
