Range Of Working Temperature Minus 40 To Plus 60 Celsius Wind Lidar Molas 3D Wind Detection System Including Beam 1 Zero Degree Setup

Product Description:

The Molas CL tower clearance lidar is a specialized type of lidar technology designed to continuously monitor the clearance distance at the blade tip in real time. This system ensures that the distance between the blade tip and the tower is constantly measured to maintain safe operational conditions.

When the detected blade clearance approaches the predetermined minimum safety threshold, the main controller of the fan unit is able to respond promptly by implementing protective actions. These measures may include reducing the rotational speed or retracting the blades, thereby preventing potential damage and ensuring operational safety.

Integrating the tower clearance lidar into existing wind turbine units offers significant benefits. It effectively prevents tower strikes, allowing units previously limited due to safety concerns to operate at higher power levels. This enhancement results in increased power generation without compromising safety.

For future wind turbine designs, the use of tower clearance lidar technology can lead to cost reductions on blades and lower the overall design stress on the units. This advancement facilitates more efficient and economical turbine construction while maintaining high safety standards.

Applications:

The Molas CL tower clearance lidar plays a vital role in ensuring the safe operation of wind turbines by addressing three key application scenarios. Firstly, it provides single point precise feedback . By continuously focusing on a fixed spatial position at the blade tip, the lidar delivers highly accurate, instantaneous clearance distance data directly to the main controller. This precise measurement is fundamental, as it guarantees that all subsequent control decisions are based on reliable information.

Secondly, the system enables threshold detection . It is preconfigured with a minimum safe clearance limit, and whenever the measured distance approaches or falls below this critical value, an alarm is triggered. In response, the controller initiates protective measures such as decelerating the rotor, adjusting the blade pitch, or executing an emergency shutdown. These rapid interventions effectively prevent tower strikes, safeguarding both the turbine structure and its components.

The third important function is trend detection . Rather than solely reacting to the current clearance distance, the lidar analyzes the rate and direction of changes in the clearance over time to predict potential risks within the upcoming seconds. This predictive insight enables the main controller to implement gentle, proactive mitigation strategies, thus avoiding sudden and harsh load fluctuations on the turbine.

Together, these three scenarios form a comprehensive safety loop. Precise feedback provides the essential raw data, threshold detection serves as the immediate defense mechanism, and trend detection offers early warning intelligence. This integrated approach supports a progression from merely “seeing” to “judging” and ultimately “anticipating” possible hazards. On existing turbines, it allows for safely lifting derating limits and increasing annual energy production. For future turbine designs, it contributes to reducing blade length and tower stiffness requirements, thereby lowering blade costs and overall design pressures.
