Range Of Working Temperature Minus 40 Celsius To Plus 60 Celsius Maximum Acquisition Distance For Long Range Detection And Performance

Product Description:

The Molas CL tower clearance lidar is a specialized type of lidar designed to monitor the clearance distance of blade tips in real-time. This advanced technology continuously measures the gap between the blade tip and the tower, ensuring operational safety and efficiency.

When the detected blade clearance approaches the predefined minimum threshold, the fan unit's main controller is able to promptly implement protective actions. These measures can include slowing down the rotation speed or retracting the blades to avoid potential collisions and damage.

Integrating tower clearance lidar into existing wind turbine units offers significant benefits. It helps prevent tower sweeping incidents, allows for an increased power output by safely raising operational limits, and ultimately enhances overall power generation performance.

For future turbine designs, the use of tower clearance lidar contributes to reducing blade manufacturing costs and lessens the structural design constraints of the units. This technology supports more efficient and cost-effective wind energy solutions.

Applications:

The Molas CL tower clearance lidar plays a vital role in ensuring the safe operation of wind turbines by addressing three essential application scenarios. The first scenario is single point precise feedback . In this mode, the lidar continuously targets a specific fixed position at the blade tip, providing highly accurate, real-time clearance distance data directly to the turbine’s main controller. This precise measurement forms a reliable basis for all further control decisions, ensuring the system’s responses are well-informed and timely.

The second scenario involves threshold detection . The system is preset with a defined minimum safe clearance limit. When the measured clearance approaches or dips below this critical threshold, an immediate alarm is raised. In response, the turbine controller initiates protective actions such as reducing rotor speed, adjusting blade pitch, or activating emergency shutdown procedures. These safeguards are crucial to preventing dangerous tower strikes, protecting both the turbine structure and its components.

The third and equally important scenario is trend detection . Rather than merely reacting to instantaneous clearance measurements, the lidar continuously monitors how the clearance distance changes over time. By analyzing the direction and velocity of these changes, the system can forecast potential risks seconds before they occur. This predictive ability enables the turbine controller to apply smooth, anticipatory mitigation measures, thereby avoiding sudden, severe load shifts that could adversely affect turbine longevity.

Together, these three application scenarios operate in harmony. Precise feedback delivers the essential data, threshold detection provides an immediate defensive response, and trend detection supplies early-warning intelligence. Combined, they create a comprehensive safety loop that spans from “seeing” the clearance, to “judging” risk levels, and ultimately to “anticipating” future threats. For existing turbines, this integrated approach helps safely lift derating limits, increasing annual energy output. For next-generation turbine designs, it contributes to reducing blade length and tower stiffness requirements, which lowers manufacturing costs and overall structural demands.
