Sound Management

Minimising sound emissions

Our wind turbines are among the quietest in their class. We achieve a low sound power level for instance by optimising our rotor blades. In order to fulfil specific requirements in sound-sensitive locations we employ our Sound Management, reducing the sound power level of the whole wind turbine in all wind speeds even further. There is a variety of sound operation modes to choose from, depending on the local conditions and local legislation. The Senvion control system controls and monitors the activation through relevant parameters such as time of day, wind direction, day of the week or date. This is how we consistently achieve optimal yields whilst adhering to individual location requirements.

Shadow Management

Avoiding shadow casting

With the help of our Shadow Management we can adhere to the specified standards for shadow casting. Via a light sensor and an integrated timer the module calculates the conditions for shadow casting and controls the wind turbine or wind farm to reduce or avoid shadow casting it.

Bat protection

For bat-friendly wind turbine operation

In the vicinity of bat colonies, flight paths or feeding grounds, bat activity increases during certain times of the day, night or year. Our control system monitors these conditions, activates the bat protection if required and automatically switches the wind turbine off. Thus we actively avoid the endangerment of the animals.

Hot & Cold Climate Version

Special solutions for cold and heat

The perfect operating conditions for wind power plants are temperatures between -20 and 35 degrees of Celsius. As wind blows everywhere, even in parts of the world, where the climate is somewhat rugged, Senvion has developed special wind turbine variants that deliver maximum performance under extreme climatic conditions.

In particular, the converter of a wind power plant should be safe from overheating. Merely dissipating its heat is not a sufficient solution to this. The component must be actively cooled down. Therefore we have designed a special hot climate version that is equipped with additional breather assemblies to ensure optimal wind turbine performance up to 45 degrees Celsius.

For locations with temperatures falling below -20 degrees, we have also come up with an adequate design. The cold climate versions of Senvion turbines feature additional heating units and some of the materials used are replaced by cold-compatible versions. That keep the wind power plant operational even at -30 degrees of Celsius thus delivering constantly high yields.

Ice recognition system

Controlled operation in icy conditions

The wind turbines can be equipped with an ice recognition system, ensuring optimal operation during the winter months. If the sensors detect the formation of ice, the control system can stop the turbine reliably and safely. As soon as the ice disappears, the wind turbine can be restarted either automatically or manually according to the configuration. Depending on the location the wind turbine can also operate with a certain amount of ice accretion. The robust blade profiles are still capable of producing a good yield. Intelligent control algorithms ensure that the wind turbine can continue to operate in a safe mode even in very icy conditions.

Hot air de-icing system

Warm air against ice formation

Ice on the rotor blades can limit turbine performance. Our hot-air de-icing system reduces ice formation by circulating hot air to the leading edge of the blade. The transfer of the heat to the outer surface results in an increased temperature of the blade so that existing ice layers melt or do not even begin to happen.
