Abstract

Abstract: In consideration that there are great calculation errors in theoretical correction of nacelle wind speed, the entire range of wind speed was divided according to changes of control strategies for wind turbine generation unit. The nacelle transfer function (NTF) was defined by higher-order polynomial fitting to identify a method for correcting nacelle wind speed based on wind measurements of the anemometer tower. It doesn’t only overcome problems like poor practicability of IEC standards NTF, but also has higher fitting precision than simple linear fitting without intervals. By introducing intermediate intervals, the problem about discontinuous NTF in different sections has been improved. The calculation example suggest that the above method is high advantageous in correcting nacelle wind speed.

Key words: wind turbine, nacelle wind speed, wind speed correction, nacelle transfer function
