WOODWARD 505/505E 简要一、概述WOODWARD 505/505E是美国WOODWARD 公司专门为控制汽轮机研制生产的以32位微处理器为基础的数字式转速调节器。

其特点是控制精度高、稳定性好、操作简便。

可根据每一台汽轮机的特性、参数，以及应用场合，对505进行组态。

适用于单执行机构或双执行机构的汽轮机控制。

调速器采用菜单驱动软件以引导现场工程师根据具体的发电机或机械驱动应用要求对调速器进行编程组态。

系统构成505/505E集现场组态控制和操作盘于一体。

操作盘用来组态505/505E，在线调整参数和操作汽轮机起停及运行。

通过操作面板上的两行液晶屏可观察控制参数的实际值和设定值。

控制回路// 505/505E控制器内有三个相互独立的控制器通道：转速/负荷控制PID回路、辅助控制PID回路、抽汽控制PID回路。

前两者通过低选输出，另外有一个PID控制回路可串接在转速控制回路上用于串级控制。

其通讯接口有三种。

控制器有三种操作模式：程序模式、运行模式和服务模式，程序模式用于组态控制器的功能以适合具体的控制要求，程序模式一旦组态后不再改变，直至需要改变控制功能时。

运行模式主要用于操作汽轮机启动正常运行至停机整个控制过程。

服务模式可以在运行状态修改参数，根据具体汽轮机控制需要通过编程组态于相应的系统。

输入及输出//本系统控制器有两个控制回路输出4～20mA,负载能力360ohm,同时可以加颤振电流为0～10mA；505/505E控制器有两个转速传感器输入，其信号输入为高选；接受二个转速探头(SE)监测的汽轮机转速信号(频率信号), 与内部转速设定值比较，经转速PID放大器作用后,输出4～20mA操纵信号。

该信号送经电液转换器I/H 转换成二次油压信号(1.5～4.5bar),二次油通过油动机控制调阀开度，调节进汽量,调整汽机出力,使汽轮机转速稳定在设定值。

如图1。

WOODWARD505也接受来自中控室或DCS的转速遥控信号(4～20mA)，以使汽轮机转速满足工艺流程的需要(4mA对应xxxrpm，20mA对应xxx rpm)。
