With wind energy, moving air masses drive wind turbines in order to generate electrical energy. In particular, low-cost onshore wind power contributes a significant portion of worldwide power. For offshore wind power, it is expected that the costs will decrease dramatically because of new technologies and new installation and maintenance concepts.

Older wind turbines will be either replaced by newer, larger systems, which is referred to as repowering, or their lifespan will be extended by installing new components. Energy yield is increased by implementing new technologies, which is referred to as retrofitting.

Robust hardware for electrical and hydraulic blade adjustment

The powerful X90 controller with integrated safety technology was specially developed for harsh environments. The control system is suitable for either electrical or hydraulic pitch systems in both onshore and offshore wind turbines and can be installed either inside or outside the control cabinet.

Increased availability with redundancy

B&R maximizes the entire automation system's resistance to failure with a redundancy options for the controller, network and power supply.

Proven safety solution for wind turbines

The safety system is completely integrated into the standard (non-safety) control system and fully transparent. B&R's extensive portfolio makes it possible to create a cost-optimized safety solution for any application, as well as custom error responses.

X20 System modules have been operated reliably for many years on several thousand onshore and offshore installations. They meet all the requirements for harsh ambient conditions, including large temperature fluctuations, continuous vibrations and salty atmosphere. To meet demands for increased availability, the various options for redundancy within the system have proven to be very effective.

The product portfolio and various remote access options for integrated Safety technology enables efficient implementation of safety circuits, for example in accordance with GL 2010 and GL 2012 guidelines.

For Azimuth adjustment, the B&R motion control product range offers torque control for reducing wear on mechanical components as well as concepts for implementing redundancy to ensure operation – even if individual motors fail.

Because of the use of open standards, it is easy to connect other systems as needed.

The highly efficient development tool Automation Studio is used to configure the system. It makes it possible to manage the work of large, geographically distributed teams and protects intellectual property.

Interfaces are available for additional tools, such as electrical configuration and simulation tools or automatic generation of code from MATLAB/Simulink or MapleSim.
