摘　　要：一种风力发电机组变桨控制系统。系统采用可编程逻辑控制器(PLC)为主控制器,控制3个桨叶同步变换桨距角。变桨系统的驱动部分由驱动器和驱动电动机组成,驱动器接收PLC提供的控制量,驱动步进电动机按照控制要求转动,带动桨叶完成规定的桨距角的旋转,达到控制风力发电机桨叶角度变化的目的。A wind turbine pitch control system,which uses a programmable logic controller（ PLC） as the main controller with controlling 3 blades synchronously changing the pitch angle. The driving part of the pitch system is composed of a driver and a driving motor. The driver receives the control amount provided by the PLC and drives the stepping motor to rotate according to the control requirements,so as to drive the blade to complete the rotation of the specified pitch angle and control the angle of the blade of the wind turbine.

关 键 词：风力发电 桨距角 PLC 变桨系统
