摘要
D EH(数字电液控制系统)作为汽轮机控制的主要核心系统,主要功能有汽轮机的转速控制、负荷控制、阀门控制,以及一次调频、快速甩负荷、O PC等特殊工况下的控制。阀门特性曲线是汽轮机D EH系统中一个重要的函数,直接影响着汽轮机进汽主调门的控制。文中介绍了某650M W核电厂汽轮机主调门流量特性曲线对D EH控制系统的影响。
As the core of turbine control system ,DEH （Digital Electro Hydraulic Control System ） has the main function of the speed control,load control,valve control,and frequency correction,Runback,OPC and other special conditions. The valve characteristic curve is a very important function in DEH system of turbine ,and directly influences the control of turbine govern valve. This paper mainly introduces the influence of turbine govern valve flow characteristic curve for DEH system.
