TECHNICAL DEVELOPMENT AT NORDEX Experience keeps us one step ahead As one of the pioneers in the modern use of wind energy, Nordex has been developing increasingly efficient wind turbines for use onshore since 1985. Since then, we have always remained true to proven principles, using tried and tested series engineering and giving top priority to the reliability of all system components. In 2000 Nordex installed the first 2.5 megawatt series turbine in the world. Since then, the company has connected more than 2,400 machines from this platform to the grid at a wide range of locations around...

MATURE TECHNOLOGY Proven concepts ensure a secure investment With the new Generation Delta, Nordex customers benefit from the know-how we have gathered in the multi-megawatt range over many years. Mature technical solutions that have proven their worth thousands of times form a sound basis for the new generation. Continuity: The electrical system Even the first Nordex multi-megawatt turbine was equipped with a doubly fed asynchronous generator and a partial converter. With Generation Delta, we have maintained this proven and highly economical electrical system. Tried and tested drive train...

Grid compatibility ensured Like the previous generations, the turbines of Generation Delta meet the grid requirements of international markets. One of the most demanding grid connection directives in Europe is the German SDLWindV (Ordinance on System Services by Wind Energy Plants). Thanks to their fault-ride-through capability, our turbines are able to bridge voltage drops easily, thereby meeting all the requirements for the System Service Bonus (SDL Bonus). In addition, the Nordex Wind Farm Management System also allows the grid operator to directly control the active and reactive power...

ECONOMIC EFFICIENCY Higher yields reduce the cost of energy In developing Generation Delta, we have met our main target – to cut the cost of energy. These Nordex multi-megawatt turbines deliver up to 31 per cent more yield from the sites, making Generation Delta turbines a particularly worthwhile investment. Larger: Rotors Nordex has designed the turbines to use a much larger rotor for each wind class. This produces higher yields. For example, the rotor diameter for machines for strong-wind locations was increased by ten metres compared to the previous model, resulting in a 23 per cent...

Stronger: Rated Output With the N100/3300, Nordex has raised the rated output of the strong wind turbine by more than 30 per cent. The N117/3000 is designed for moderate wind speeds and has a 20 per cent higher rated output than the previous model. This has a positive effect on the energy yields of the Delta turbines. In spite of the considerable increase in output, the sound power levels remain stable for each class. Higher: Towers New and higher hub heights produce even greater yield increases and make siting possible, even in wooded areas or locations with complex topography. For the...

QUALIT Y AND RELIABILIT Y A focus on high availability To ensure that our turbines perform reliably, we conduct exhaustive testing. We certify the quality of all components and manufacture in continuous flow. The average availability of all turbines covered by Nordex Service stands at 98 per cent. We ensure this high level of availability by consistently developing the central systems, which further contributes to reductions in the cost of energy. Extreme tests for hardware and software In the Nordex Test Centre, engineers test the components and systems of the new turbine generation under...

Advanced control infrastructure Nordex has equipped the new turbine generation with the Profinet communication system. Its ethernet-based fieldbus transfers turbine data rapidly, reliably and by priority. All actuators and sensors in the turbine control systems, as well as the different module options, are directly integrated into the network. This ensures improved diagnostics and the reliability of the system. Optimised drive train The drive train design of Generation Delta reduces the forces acting on the individual components, taking greater strain off the robust rotor bearing....

SERVICE AND HSE Fast and safe turbine O&M Generation Delta is designed so that service operations can be conducted rapidly and safely. This reduces ongoing operational costs. We make no compromise when it comes to HSE – the turbines of the new generation meet the most stringent requirements. Protected hub access The new spinner, a complete housing for the rotor hub, provides rapid and protected access to the hub. This means that service work can be carried out in a wider range of wind and weather conditions. This is of particular advantage in cold regions – making it possible to reduce...

Ergonomics and safety When we were developing the new multi-megawatt generation, we gave high priority to designing the turbines as a particularly safe and spacious workplace. In case of an emergency, the platform also offers extended escape and rescue routes. All systems are easily accessible for maintenance. Nacelle components weighing less than one ton can be reached with the on-board crane and, if necessary, can be exchanged without additional equipment. Annual service interval The technical design of Generation Delta allows for an annual service interval. Automatic lubrication of the...

SOLUTIONS FOR STRONG WIND High yields in rough climates Wind sites with a rough environment call for mature, robust technology. With the turbines of Generation Delta, Nordex offers the proven 100 metre rotor now also for IEC 1 locations. Thanks to the large rotor diameter and the higher rated output, the N100/3300 obtains much higher energy yields at sites with strong winds compared to the previous model. This turbine is available with hub heights of 75 and 100 metres. To ensure high yields at sites in cold climates, Nordex equips the N100/3300 with the efficient anti-icing system as an...
