Abstract: Aiming at the problems of high cost and difficulty in the traditional measure method on drive chain efficiency of domestic wind turbine, the optimal fitting of nacelle transfer function (NTF) based on divided interval was researched and effectiveness of NTF was discussed. In addition, a new method to measure the drive chain efficiency more reliable and convenient was proposed. By using this method a test was taken on a 2.0 MW wind turbine in a flat terrain and wind farm to measure its drive chain efficiency. The experimental data was verified by the results by traditional method. The results indicate that they were coincided well, therefore by this method nacelle drive chain efficiency can be measured accurately and greatly reduces the measurement costs and implementation difficulty.

Key words: nacelle transfer function(NTF); wind turbine; drive chain efficiency; measure
