Measuring the Power Curve of a Small-Scale Wind Turbine: A Practical Example

Abstract

We show that the measurement of the power curve of a small-scale wind turbine system following the IEC 61400-12-1 standard might lack consistency. This is due to characteristics specific to small-scale wind turbines. We give recommendations to ensure consistency, accuracy and reproducibility of the measurements. Besides, in the hope of making the standard more accessible, we clarify the impact of various parameters such as generator heating, battery voltage, controller settings, furling system and anemometer position. Our Matlab code used for data processing is included.
