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
