汽轮机数字电液控制系统(DEH)的结构功能及其与CCS的接口

Configuration and Functions of Steam Turbine DEH Control System and Its interface to CCS

介绍了汽轮机数字电液控制系统 (即DEH系统 )的一般功能及硬件、软件的结构。着重介绍了协调控制系统(CCS)与DEH系统密切相关的几个重要信号———CCS指令信号、RB信号、FCB信号的产生 ,它们与DEH相互联系的方式以及对DEH指令信号的作用 ,并剖析了投入协调运行后汽轮机控制系统、协调控制系统作为一个整体时的工作原理及工作方式。

This paper introduces the general functions,hardware and software configurations of DEH system for steam turbine control. It focuses on the generation of some important signals closely related to Coordinate Control System (CCS) and DEH system, such as CCS instruction, RB, and FCB signals, and the mode of interrelation between these signals and DEH, and the action to DEH instruction signal.When coordinate control system is put into operation, the working principle and operating mode of turbine control system combined with the coordinate control system are also analyzed in this paper.
