Windkraft Simonsfeld equips entire Senvion fleet with fos4X ice detection system

​Munich/Ernstbrunn – Windkraft Simonsfeld AG has equipped its entire Austrian Senvion fleet of 35 wind turbines with fos4X ice detection systems just in time for the start of winter 2019/20. Furthermore, the retroX system with additional functionality for performance enhancement and digitalization of wind turbines was installed at four selected turbines.

Windkraft Simonsfeld AG already equipped some of its wind turbines with the fos4X ice detection system Rotor Ice Control in 2018. The reliability, performance and price competitivity of the system were so convincing that all the remaining turbines in the Senvion fleet were retrofitted the following year.

β€œThe reliability and performance of the fos4X ice detection system are outstanding in our wind farms. The systems will already have amortized in our wind farm Kreuzstetten in the 2nd winter.”

Dieter Schreiber, Head of Monitoring and Innovation, Windkraft Simonsfeld AG

Additional functionality with retroX system

On four selected wind turbines with performance anomalies, the retroX system was installed instead of the standard ice detection. retroX consists of a sensor platform and intelligent software offering extended functionality. In addition to ice detection, the system enables the identificiation of yaw and pitch angle misalignments and the logging of loads experienced during turbine operation.

The data collected by the fos4X systems is directly transferred to the monitoring system of Windkraft Simonsfeld and is integrated into the in-house operation management system. This allows service visits to be optimally planned, downtimes reduced and reliable turbine operation guaranteed.
