Abstract: Taking the wind power system as a research, the metal belt continuous variable transmission (CVT) was put forward to adjust the power frequency of wind driven generator. The physical model and adjustment principle of metal belt CVT in wind power system were given, while both mechanical frequency conversion speed ratio model and control system mathematical model were established. In mechanical frequency conversion control system of wind driven generator, the design of hardware and software was finished. Based on the experimental analysis, the output frequency of wind power system is 48 Hz, which verified the correctness of mechanical frequency conversion mechanism.
Key words: wind power system；mechanical frequency conversion；metal belt；continuous variable transmission；constant frequency
