摘要
液力调速行星齿轮装置通过改变液力变矩器导叶开度,可以将变化的风速恒速输出,使得风轮追踪最佳风轮速度,提高海上风能利用率,保证同步发电机的转速维持同步转速,使发电频率稳定,不需要变频装置,提高风电机组的可靠性。建立海上风电机组传动系统的数学模型,分析液力调速行星齿轮装置参数对海上风电机组系统性能的影响规律。根据海上风电机组的运行特点和要求设计液力调速齿轮控制系统。
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.
