High wind speed hysteresis

WebMar 26, 2024 · For most Wind Turbines, useful wind speeds range from 9 mph to 36 mph (4 m/s to 16 m/s) Within this wind speed range anemometer accuracy and measurement repeatability are of utmost importance. As stated in the paragraph above, any measurement error is amplified to the 3rd power (V 3 ). WebHysteresis is applied by feeding back to the positive input a small fraction of the output voltage (which is at an upper or a lower limit). This voltage adds a polarity-sensitive offset to the input, increasing the threshold range.
