摘　　要：介绍一种风力发电机组变桨控制与驱动系统。系统以可编程逻辑控制器(PLC)为主控制器,控制3个桨叶同步地变换桨距角。变桨系统的驱动部分由驱动器和步进电动机组成,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,达到变桨控制与驱动的目的。A pitch control and drive system of wind turbine is introduced. The system uses a programmable logic control（PLC） which controls three blades to change pitch angle simultaneously. The driving unit of pitch control system is made of driver and stepper motor. Motor drivers receive control parameters form the PLC, and drive the stepper motors to rotate according to the control requirement. In the meantime, the stepper motors make blades to rotate by a required angle. The whole process realizes pitch control and driving.
