【摘要】 变桨距控制器用于实现功率调节和桨角控制,介绍了液压驱动和电控驱动两种桨距控制系统的不同,然后讨论了CAN总线在风力发电机组桨距控制中应用的可行性。并介绍了一个基于CAN总线设计的液压驱动桨距控制系统的硬件设计、软件流程和功能实现。最后总结了CAN总线在该系统应用的优点。

【Abstract】 Variable pitch controller is used to realize the power regulation and pitch control of wind turbines.The difference between two schemes of the pitch-controlled system,hydraulic control and electro-motor control,was described.Subsequently,discussed the feasibility of CAN-bus used in the pitch controller.As an example,a design of pitch controller based on CAN-bus was also presented,with the description of its hardware design,software flow and implementation of control functions.Finally,the merit of CAN-bus in this system was summarized.
