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

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 and data processing. 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 importance of various test parameters such as anemometer position, battery voltage, and controller settings. Our Matlab code used for data processing is included.
