Application of ultrasonic wind speed sensor in wind power generation
The development and utilization of new energy and renewable energy is one of the important strategic measures to solve China's energy and environmental issues. Among many renewable energy sources, wind power generation technology is by far one of the most suitable technologies for large-scale power generation, and the application of power electronics technology in wind power generation can greatly improve the operating characteristics of wind turbines. It also plays an important role in normal operation.
With the development and progress of sensor technology, more and more sensor technologies have been applied to the power industry, and play an important role in promoting the improvement of power operation quality and efficiency. Let's take a look at the application of ultrasonic wind speed sensors in wind power generation with everyone.
Wind power generation has the characteristics of unstable wind speed, which brings certain difficulties to the stability of wind power generation, and because wind energy cannot be directly stored in the wind power generation system, in order to ensure stable power supply, it is necessary to use ultrasonic wind speed sensors to stabilize For the wind speed, the French LCJ Capteurs ultrasonic wind speed sensor - CV7 - OEM provided by Gongcai.com. Compared to conventional anemometers, which have rotating mechanical parts, these moving parts can easily damage the sensor. While the ultrasonic sensor is designed to avoid any mechanical parts to ensure the best and more reliable operation. Ultrasonic wind speed sensors are long-term stable and maintenance-free.
And French LCJ Capteurs ultrasonic wind speed sensor - CV7-OEM can provide 4 independent test data. The correctness check is used for the calculation of the head wind vector. This method provides a wind speed sensitivity of 0.15m/S, reliability and excellent linearity up to 40m/S.
Sound (and ultrasound) on the other hand is transmitted by the motion of the fluid it passes through. The electro-acoustic transducers communicate with each other two-by-two using ultrasonic signals to determine the wave travel time difference caused by the airflow according to the orthogonal axes. The CV7-OEM transducers communicate with each other to provide four independent measurements, while the headwind measurement vector is used for calculations. These measurements are combined to calculate the wind speed and direction relative to the reference axis. Temperature measurement is used for calibration. The design of the sensor reduces the influence of the tilt angle (based on the shape of the space, the influence of the sensor tilt angle is partially corrected).
