A system for measuring Time of Flight (ToF) of wind using multiple ultrasonic sensors is introduced here. The time taken by the ultrasonic sound to travel from a transmitter to a receiver is expressed as the Time of Flight. The time interval between the transmission and reception decreases if the direction of wind aids the direction of propagation of sound. If the direction of propagation of sound...
The objective of the proposed scheme is to extract the maximum power at different wind turbine speed. In order to achieve this, MPPT controller is implemented on the rectifier side for the extraction of maximum power. On the inverter side normal closed loop PWM control is carried out. MPPT controller is implemented using fuzzy logic control technique. The fuzzy controller's role here is to track the...
This paper introduces a low cost receiver for wind velocity measurement using FPGA with multiple ultrasonic transceivers. Wind speed is derived from the time taken by ultrasonic sound to travel between an ultrasonic transmitter and receiver. The receiver section of ultrasonic anemometer acquires the data for time of flight calculation from transmitter section and wind velocity is calculated. Ultrasonic...
