BladeVision

Wind is complex. It doesn’t just blow from the front or the side. To describe the wind feeding a wind turbine, at least seven quantities are needed: speed, direction, vertical shear, horizontal shear, veer, vertical velocity, and turbulence level. Knowledge of these quantities helps maximize turbine performance, and life. It also helps explain why some neighboring turbines perform differently. Actual sensor systems are rarely capable of meeting this challenge. However, our most advanced sensor has been designed to do exactly that: Nidec’s SSB BladeVision doesn’t just measure wind speed and direction: It provides a complete wind-field description over the swept area of the blades. This completeness provides operators with important data about wind factors affecting the performance of different types of WTGs in their wind park.
