Senvion services

Our engineers have developed a series of performance enhancing hardware and software technologies to further improve the performance of your Senvion turbines. Each feature can achieve an increase in Annual Energy Production (AEP). You can choose the feature which delivers the highest increase in output based on site-specific conditions or combine them to benefit from the aggregate increase in AEP.

If you wish to increase significantly the Annual Energy Production (AEP) of your Senvion wind turbines, we have the solution for you! The Turbine Control Upgrade 2.0 is a smart combination of five high-performance features increasing the AEP of Senvion turbines by 1.8% on average*. It consists of further optimization of two proven features provided within the previous version and the addition of three newly developed features. The illustration below visualizes how the power curve of the wind turbine behaves when the solution is installed.

Benefits of Turbine Control Upgrade 2.0:

Particularly effective for turbines located on complex terrain and low air density
Site specific adjustment of start-up speed based on self-learning algorithms
Optimized yaw behavior increases the AEP
Reduction of loads due to improved rotor alignment
Increased power output in upper partial load area by higher rotor speed
Optimized pitch behavior under high turbulence wind conditions increases the annual energy production
Reduced idle time increases output at high wind speed

*depending on turbine type and sites conditions.

The efficiency of wind turbine rotor blades is decreased, when flow separation from the blade occurs. The Vortex Generators for Senvion wind turbines are fin-shaped aerodynamic devices which optimize airflow. They significantly reduce the occurrence of flow separation, stalling of the blade and increase lift and thus output. Vortex generators can be retrofit to achieve a significant increase in AEP.

Benefits of Vortex Generators

Increase in AEP
Based on mature and proven aerospace technology
Service and maintenance included in the Integrated Service Package
Developed in-house for optimal effectiveness

Noise protection is of great importance for wind farms located close to residential areas. The extended serrations, a comb-like structure which is attached to the blade tip and helps break up airflow around the blades, will reduce the Senvion turbines sound power level by up to 2dB.

Benefits of Serrations

Increase of overall blade area to add lift
Up to 2dB reduction of turbine sound power level
Optimization of sound management to prevent sound curtailment
AEP increase through prevention of sound curtailment

Due to icing, the wind turbines often need to be stopped when ice is detected, resulting in AEP losses. The product ‘Operation with Ice’ maximizes your turbine’s performance under icy conditions by reducing the operating power efficiently and reliably, thus reducing complete stops. When no ice is detected by the ice detection systems, the turbine goes back into normal operation.

Benefits of Operating with Ice

Increase in AEP in icy conditions

The product Rotor Blade Ice Detection reliably detects the presence of ice on the blades and automatically starts the turbine when the rotor is free of ice. No visual inspection is required. Fiber-optic sensors mounted on the rotor blades measure the natural frequency of the rotor blades which changes when ice forms.

Benefits of Rotor Blade Ice Detection

Reliable ice detection on the rotor blade reduces downtime
Individual monitoring of each blade during operation and at a standstill
Automatic restart if no ice is detected, without visual inspection
No increased risk of lightning strikes thanks to fiber-optic sensors

In Germany, the new Energy Collection Act (EnSaG) will require on-demand activation of the aviation lights system when an aircraft approaches wind turbine at night (known as BNK). The Smart Aviation Light is compliant with the German AVV law requirements. This solution is also interesting for other countries to enhance public acceptance of wind energy. With this solution, the aviation lights of the wind turbines are only activated at night when an aircraft is within an air space with a radius of four kilometers around each turbine.

Benefits of Smart Aviation Light:

Compatible with the existing service contract
Compatible with all turbine systems
Compatible with renowned signal providers
Compatible with neighbouring wind farms
Equipment covered by the existing service contract (Senvion ISP contract)
