Rotor blade

Continuous rotor blade condition monitoring
Back to Wind turbine generators


  • Solutions for ice detection

    The ice detection system from Phoenix Contact measures the severity of ice accretion on the rotor blades and ensures the reliable operation of the wind turbine generator.

  • Solutions for load measurement

    The Rotor Monitoring System (RM-S) from Phoenix Contact continuously monitors the vibrations in the rotor blades of a wind turbine generator.

When dealing with increasingly large rotor diameters, condition monitoring on the rotor blade is a sensitive task. By using the right type of monitoring, system efficiency is increased and important safety functions are implemented to prevent damage to the wind turbine generator.

Your advantages

  • Maximum availability of wind turbine generators with robust components, even under extreme conditions
  • Easy integration into existing systems, thanks to open interfaces
  • Maintenance work can be scheduled and parameterization adjusted, thanks to remote access

Rotor blade monitoring with Blade Intelligence

New technologies and wireless sensors enable long-term and efficient maintenance management, while also allowing for efficient retrofitting of older turbines.

Thanks to the combination of ice detection, lightning monitoring, and load monitoring, our Blade Intelligence blade monitoring solution lets you keep an eye on the condition of your rotor blades and thus respond to events at an early stage. The Blade Intelligence solution is available in different versions, and can also be reliably integrated into existing systems at a later time.

Complete solution for efficient operation

The modular design of the Blade Intelligence solution allows individual solutions to be combined as needed based on the requirements. Sensors developed specially for installation on the rotor blade provide all of the data necessary for processing in a common evaluation unit.

Extensions with additional sensor technology are always possible. New technologies and wireless sensors allow sustainable and efficient maintenance management.

Operation and visualization

System status visualization  

System status visualization

The data from all sensors is visualized clearly on an HMI web panel. The intuitive interface gives you quick access to all functions and provides you with a complete overview of what is going on with each and every rotor blade.

Installation documentation

Support during installation  

Support during installation

Our app provides you with digital support when you are installing the sensors. Right from the start, when affixing and setting up the sensors on the rotor blade, photos and other information on the installation can be documented in the app. This data is transmitted to the respective controller.

Matlab Simulink integration

The Blade Intelligence system is ideally suited for use in modern wind turbine generators because it uses PLCnext Technology. Integrating Matlab Simulink allows blade heating control models to easily be uploaded to the controller and integrated. With this approach, the blade heating system can react directly to changing conditions on the rotor blade.
