摘　　要：针对火力发电厂汽轮机专用阀控卡与转速卡的快速响应需求,基于现有常用实现方案所具有的局限性,提出一种响应更快速的汽轮机阀控卡与转速卡的设计方案,来改进该两种专用卡件的响应速度,对汽轮机控制具有重大意义。方案已应用到工程中,运行情况良好。Aiming at the fast response requirements of the special valve control card and speed card for steam turbines of thermal power plants, based on the limitations of the existing implementers, a design scheme for faster response valve control cards and speed cards of steam turbines is proposed to improve the response speed of the two special clamps is of great significance to the control of the steam turbine. The scheme has been applied to engineering applications and the operation is good.
