| Abstract: | To ensure large scale wind turbines work efficiently, stably and reliably, a hydrodynamic speed adjusting system is proposed, in which planetary gear transmission matches with torque converter with adjustable guide banes. Power flow of the system is calculated by node method, constraint conditions of structure parameters of the speed adjusting system are obtained and the principle of the speed adjusting system is described. It has important significance on the optimization of power distribution scheme. The mathematical model of wind wheel is established and the performance of transmission system is calculated. The relation between structure parameters and speed adjusting system is obtained. The effect of torque converter with adjustable guide vanes on the speed adjusting system is analyzed emphatically, which lays a foundation for the design of torque converter with adjustable guide vanes. |
