Nordex Control ™

More than 2,600 Nordex turbines have already been fitted with the tried and tested Nordex Control™ system. It handles the control, adjustment and monitoring of the turbine systems. The permanent, protected access to turbine and wind farm data on site or remotely is browser-based, interactive and secure. With its modular structure and standardised interfaces Nordex Control™ can be flexibly configured to suit the customer’s SCADA requirements.

Rotor blade design

Nordex uses proven aerodynamic designs for the rotor diameters of 100 and 117 metres. Nordex engineering developed the NR50, NR58.5 and NR65.5 blades in-house. This allowed us to realize an optimal concept for the overall turbine system. The efficient rotor blades match the respective turbine technology perfectly.

Grid compatibility

The turbines of Generation Delta meet the grid requirements of international markets. Thanks to their fault-ride-through capability our turbines are able to bridge voltage drops easily. In addition, the Nordex Wind Farm Management System also allows the grid operator to directly control the active and reactive power of the wind farm in the grid.

Nordex Anti-Icing

Icing on the rotor blades can reduce the efficiency of a wind turbine generator as well as lowering its availability. The proven Nordex anti-icing-system heats the most aerodynamically important areas of the rotor blades and efficiently reduces icing levels. Nordex customers can rely on their turbines for dependable yields and maximum availability also in cold regions.

Sound power

Despite the considerable increase in nominal output, the sound power level of the N131/3000 has been further reduced - a crucial factor for optimising windfarms and facilitating permitting especially in populated areas.
In addition, Nordex also offers a wide range of noise-optimised operating modes to make it possible to run WTGs at particularly noise-critical locations. The optimum yield is still achieved thanks to the improved sector-cut-out modes available through Nordex Flexible Sound Management functionality.

Service interval

The technical design of Generation Delta allows to increase on-site service intervals to an annual frequency. Automatic lubrication of the bearings in the pitch system replaces manual processes. These bearings as well as the main bearing and the generator bearings are continously supplied with lubricant making them less susceptible to wear. This results in a longer service interval and minimises the O&M expenses.

Drive train design

The drive train geometry of Generation Delta reduces the forces acting on the individual components, thereby taking greater strain off the robust rotor bearing. On top of this, innovations in the cooling system of the drive train ensure constant temperatures over a wide operating range – with lower internal energy consumption.
