EVEN MORE FLEXIBILITY, EVEN MORE POWER

Based on almost 35 years of experience, the Nordex Group is an expert in connecting proven technology with innovative engineering. With the new N149/5.X we have incorporated our experience from developing and testing the Delta4000 series in the last two years and driven our flexibility approach to the next level. Based on the proven Delta4000 architecture, the N149/5.X covers a wide range of power modes in the 5MW+ range and increases the suitability even further in low- and medium-wind sites. Depending on investment criteria in the customer’s business case the wind park can be optimized with regards to capacity factor, rating, lifetime and sound requirements. In addition, this flexibility offers opportunities to optimize the revenues in line with PPA structures and merchant price profiles.

Flexibility provides higher yields

Based on the positive feedback of our customers and the success of the N149/4.0-4.5 we have driven the flexibility of the N149/5.X to the next level. The N149/5.X has a variable maximum output in the 5MW+ range, creating a yield of up to 17 per cent higher compared to the N149/4.0-4.5 at similar site conditions.

Proven rotor blade design

The N149/5.X uses the proven rotor blade of the N149/4.0-4.5. By using this modular approach our customers can be certain when it comes to turbine performance.

Hub heights

Hub heights of up to 164m are available, incl. site specific designs using a variety of tower technologies

Reduced sound power levels

Despite the substantial increase in output, the maximum sound power level of the N149/5.X has been kept at a very low level. If the turbine is operated for example at 5.5MW rating, the maximum sound power does not exceed 104.8 dB(A), making it currently one of the quietest turbine in the 5 MW+ class.

DESIGNED TO KEEP MAINTENANCE COSTS AT A MINIMUM

Design lifetime

The turbine is designed for a minimum lifetime of 20 years while, depending on wind farm site conditions, a project specific operating life of up to 25 years can be achieved.

Reduced service effort

The technical concept of the Delta4000 series minimises the service effort over the whole lifetime. Every component was consequently designed to cater for optimized operations and maintenance. Smart repair concepts as well as the latest crane and lifting technologies lower the maintenance effort and reduce downtimes.

Wind Turbine Engine

Optimised Design

BETTER RELIABILITY AND ECONOMIC EFFICIENCY

Reliable drivetrain concept for high performance and availability

The drivetrain concept is based on a modular system with three-point suspension and a high speed gearbox. An architecture continuously further developed with proven suppliers to reach new performance levels.

Same nacelle dimensions

The N149/5.X uses the same nacelle architecture and dimensions as all other Delta4000 turbines. Converter and transformator are integrated in the nacelle to minimize electrical losses and reduce installation effort in the field.

Upscaled electrical system

In order to reach the 5MW+ nominal power the electrical system of the Delta4000 was upscaled. We have remained faithful to the proven and highly economical electrical system with a doubly-fed asynchronous generator and a partial converter - a system which has proven its reliability for more than two decades in the field.

Grid Compatibility

The N149/5.X meets the grid requirements of demanding national and international markets, such as the German high voltage directive (VDE-AR-N) or the ENTSO-E Grid Codes.

Turbine Control System

The control system uses state-of-the art industry PLC based embedded technologies. This provides modular and flexible structures with high focus on safety, reliability and security. Ready for the future it’s not only well integrated in today SCADA system. Each turbine is also directly communicating with Nordex central NxOS Control Center. It enables new features like remote and automatic parametering and software updates.

Tapping into colder locations

The proven Nordex Cold Climate Package enables wind farm development even in some of the coldest locations. Turbines of the cold climate variant (CCV) can operate in outside temperatures as low as minus 30 degrees Celsius.

Anti-icing System

The market-leading rotor blade Anti-icing System exploits the excellent wind resources available in cold climate regions to the full, leaving no spare MWh untapped with a warranted performance level.
