Variable speed input of the transmission system can be achieved with constant speed output via the regulation of adjustable guide vanes angle in the hydrodynamic torque converter. Wind wheel can trace optimal speed and the utilization ratio of offshore wind power is higher. Constant speed output of the transmission system ensures the speed of the synchronous generator to maintain synchronous speed, which improves the reliability of wind turbine. The influence law of the train parameters on the performance of offshore wind turbine transmission system is analyzed based on the mathematical model of offshore wind turbine transmission system. The corresponding control systems are designed according to the characteristic of offshore wind turbine in the different operational phases.
