Abstract In order to study the effects of environmental factors on maximum power point tracking (MPPT) control of wind turbine, taken power signal feedback algorithm as an example, the mechanism of temperature and humidity affecting PSF algorithm is analyzed based on mathematical relationships of temperature and humidity with air density. Then this paper presents the method for the optimal power curve acquisition, the implementation process and flow chat of PSF algorithm considering temperature and humidity. The influence of loss of wind turbine is considered in this PSF algorithm. The models with doubly fed induction generator wind turbines based PSF algorithm are built on Matlab/Simulink platform. At last, the simulation results and field test in wind farm show that the PSF algorithm considering temperature and humidity can obtain high wind energy conversion efficiency.
