摘要

提出一种用于风力发电的新型自稳速传动系统,在风轮变速旋转时,可实现传动链末端的同步发电机转子转速恒定。自稳速系统由差动轮系、差速器和恒转速电动机构成,利用差速器左、右半轮叠加风轮时变转速和电动机恒转速,差速器壳体即可自动调节差动轮系输出轴转速至恒定。对自稳速风电系统进行运动学分析,并建立了"双输入-单输出"三轴系统的"质量-弹簧-阻尼"模型。利用SIMULINK软件进行仿真,以湍流风作为模型输入,为模型设置不同的转动惯量、刚度、阻尼,分析了不同参数值对输出轴转速和转矩的影响,并分析了输出轴转速的频率成分,将其与固有频率进行比较以评估系统共振的可能性。

Abstract

A novel self-stabilizing speed transmission used for wind power generation is proposed. It can keep the constant speed of synchronous generator amature under the time-varying speed of wind rotor. The self-stabilizing speed transmission consist of differential gear train,differential mechanism and constant speed motor. The time-varying speed of wind rotor and constant speed of motor are superimposed by the left wheel and right wheel of differential mechanism. The shell of differential mechanical can automatically adjust the output speed of differential gear train to stable. The kinematics analysis for the self-stabilizing speed wind turbine is carried out,and the mass-spring-damper model of the transmission is established for three shafts system with double inputs and single output. The simulation is executed in SIMULINK software with turbulent wind input.The influences on output shaft speed and torque under different inertia,stiffness,damping are discussed. The frequency of the output shaft speed is compared with natural frequency in order to evaluate the possibility of the system resonance.
