All ATB wind turbines have been designed according to IEC 61400. ATB wind turbines are built according to the concept of a variable speed synchronous generator with a full converter system and hydraulic pitch control. That concept is characterized by maximum energy yield and high efficiency. The sophisticated power converter concept permits powerful and rapid active and reactive power control, and thus creates the conditions to maintain network stability.

Bankable and Investment-Ready 

In a continuously changing market, the strength of covenant and the manufacturer's warranties and services have become key to finance wind energy projects.

ATB provides an end-to-end service in the manufacture, construction, operations and maintenance of ATB turbines, providing complete accountability and a high degree of reliability with its ATB Wind Service lifetime plan. Technical excellence and customer-oriented support put our products at the top of the sub-megawatt market.

High Efficiency 

Every ATB wind turbine is built to the highest standards of engineering, performance and quality. ATB has developed highly efficient wind turbine technology reaching the rated output power at lower wind speed than most available models and this resulted in ATB wind turbines be known as "“best-in-class” in the sector.

Advanced Pitch Control 

ATB wind pitch control system automatically and synchronously adjusts the pitch of each blade to optimize efficiency. The blade adjustment is made extremely quickly, reacting to changes in wind conditions within around 0.1 seconds.

Blade and Nacelle

Our advanced blade design contributes to optimize power generation. The technology also has an integrated slow speed shaft that reduces space constraints in the nacelle by avoiding main bearing and lengthier slow speed shaft.

Advanced Pitch Control

ATB Wind Turbines is equipped with a specialized cooling system that guarantees continuous and efficient operations under diverse climatic conditions. This feature is a must for varying temperature conditions across regions.

Reliability

Engineering excellence and exhaustive testing are the cornerstones of our wind turbine design, production and deployment process. Throughout initial design and subsequent revisions, all of our models are manufactured to ensure our customers can count on their turbines over a 20-year lifespan.

Remote Monitoring

The remote control allows users to remotely monitor the turbine’s operational status, live energy production, wind speed and power output.

The operating parameters data stored in the control unit of the wind turbine are constantly monitored and automatically adjusted during operation. The parameters are tuned to each site to ensure the safe and automatic operation of the wind turbine in all situations.

Safety

When the turbine control system detects any fault, such as high wind or a grid power loss, the pitch system activates, rotating the blades and safely stopping the turbine. In addition, a mechanical parking brake supports the aerodynamic brake and brings the rotor to a standstill until the condition is cleared.

Product applications

ATB Wind Turbines are well-suited for both On Grid & Off Grid applications such as:

• Self-consumption
• Net-metering
• Community projects
• Islands or remote areas
• Hybrid renewable systems

A variable pitch-controlled wind turbine with a 54 m rotor. The turbine is available in 50 m or 73 m hub heights. The towers are manufactured using the highest quality steel with a durable C5 outer protective coating to ensure a minimum lifespan of 20 years even under the most severe operating conditions.

The technical availability has exceeded 98% in the wind farms managed by S&G’s Engineering in Germany. Full reference data is available, dating back to 2003, to verify the highly successful operational track record of our design. 

ATB 500.54 IEC Type Class III with a 54 m rotor is a grid-friendly machine which incorporates the latest features of electronics and electrical systems and meets the most demanding grid conditions.

The latest electrical configuration upgrades ensure that the turbine meets the G59 and all current European grid codes.

Blades are individualy adjusted via maintenance-free AC-motors. The intelligent torque control ensures a high-power output due to the innovative permanent synchronous magnet generator.

The turbine works according to the concept of variable speed and power control by blade pitch. The turbine has a gearbox. Speed is varied via a synchronous generator with a full converter.

ATB 500.54 has been designed according to IEC 61400-edition 3 (latest edition).
