介绍了双速电机（Dual Speed Generator，简称DSG）软并网型风力发电机组控制系统的构成和特点。系统采用双向晶闸管的软切入法，使DSG 并网。这种软并网可以实现一个平稳的并网过渡过程而不会出现冲击电流。该控制系统采用了可编程逻辑控制器（PLC）、触摸屏和工业控制计算机等设备，实现了风力发电机组的自动起动、自动
进行高低速电机之间的切换、自动保护等功能，使该WT 组能够在长期无人值守情况下安全运行。

Abstr act：The paper introduces the structure and characteristic of soft cut-in control system for a wind turbine dual
speed asynchronous generator.The system use soft cut-in method based on bidirectional thyristor.This method can realize a
smooth start process without overshoot current.The control system can automatically start and switch between the two
speeds of the generators and automatically be protected by using Programmable Logic Controller （PLC），touch panel and
industry control computer.
Key words：asynchronous generator；thyristor；wind turbine；control system
