摘要
针对变频器对风电系统的影响,设计了一种自稳速传动系统,可用于风力发电机的恒频输出。从机构学角度对该系统中的电动机与差动轮系进行特殊设计,维持电动机转速恒定,即可实现系统变转速输入、恒转速输出。搭建了采用该系统的并网型风电机组模型,通过FAST和SIMULINK软件的仿真试验,验证了该系统的有效性。
Aiming at the influence of frequency converter on wind power system,a speed self-stabilized drive system is designed and can be used for constant frequency output of wind turbine. The motor and the differential gear train are designed specifically to maintain a steady motor speed from the angle of mechanism theory. The drive system can output constant speed with variable input speed. A model of grid-connected wind turbine using the speed self-stabilized drive system is build. The effectiveness of the system is verified through the results of simulation experiment with FAST and SIMULINK.
