With the growing concern from ever increasing oil prices and the growing impact of greenhouse gases, renewable energy solutions such as wind power are on the rise. Because of this trend toward “green” energy solutions, BEI Ideacod’s absolute encoder products now play an instrumental role in exploiting this renewable energy source.
The Posi+ is used to monitor blade position as well as measure the speed and consequently the power output while also aiding in the orientation of the wind turbine.
Orientation of the wind turbine: The absolute encoder Posi+ supplies the head position with an accuracy of 0.01º. The turbine is oriented so that it faces the wind direction for optimum efficiency.
Monitoring of blade position: The Posi+ accurately determines blade angle. A high resolution is utilized to swivel the blades to one hundredth of a degree in order to position the blades at an optimum angle with respect to the wind, once again, making operation as efficient as possible.
Monitoring the speed and the power: The Posi+ is mounted behind the generator and delivers speed information for power regulation. Accuracy of pulse generator signals allows for fully reliable regulation thereby stepping up control and overload/over-speed detection.
Key Features Include:
- Compact, robust design
- Excellent resistance to shock & vibration
