Let’s take closer look at a typical sensor for a large wind turbine. The sensor mounts to the main frame; its gear is driven by the yaw ring. This sensor employs an incremental encoder that tracks nacelle position, along with a group of limit switches dedicated to cable twist control Here we can see the…
Let’s take a closer look at some of the sensors used in the yaw control system. Potentiometers,encoders and ultrasonic sensors may be used to detect wind direction. A potentiometer is a variable resistor consisting of a resistive strip, 3 terminals, and a movable wiper. The movable wind vane is connected to the wiper. As the…
