单阀蒸汽透平转速控制方案分析

Analysis of Single-valve Steam Turbine Speed Control Scheme

乌石化二合成引风机采用单阀蒸汽透平驱动,使用一段时间后,波动较大,经改造采用伍德沃德调速器加执行器控制,并根据实际情况修改了一些组态信息,顺利实现控制功能,投用成功。

The Wuji Petrochemical II Synthetic Induced Draft Fan is driven by a single-valve steam turbine.After a certain period of use,it fluctuates greatly.Woodward’s governor and actuator control are used after modification,and some configuration information is modified according to the actual situation.Smooth implementation of control functions and successful investment.
