The brief
To run wind turbines as efficiently as possible, they should operate in their optimum speed range across all wind conditions. In strong winds, a failure caused by exceeding the maximum speed must also be prevented, as this can not only destroy the turbine but, for example in the event of a rotor failure, also pose a danger to people. Continuously monitoring the rotor speed can, for instance, allow the turbine to be turned out of the wind if the limit is exceeded.
The solution
NewTec supports you in developing speed monitoring systems with a high level of failure safety (SIL 3). To identify bearing damage, monitoring the vibration of the shaft is also possible. So that the system works reliably across a wide temperature range, temperature-resistant two-channel processors with redundant sensor technology are used. The sensors are designed to be insensitive to contamination or fouling by lubricants, or to trigger maintenance if fouling becomes too severe.
On request, our safety experts also develop software to control the speed monitoring, including a safety operating system. With our specialist know-how, we additionally ensure secure transmission of the speed and vibration data to the turbine control.
