汽轮机数字电液控制系统在大型火电机组中的应用

Application of Digital Electro-hyd raulic Control System in Steam Turbine for Large-sc ale Thermal Power -generating Unit

丰城电厂4×300MW单元机组汽机控制采用了以WDPF集散系统为基础而构成的汽轮机数字电液控制系统(DEH-Ⅲ)。以DEH-Ⅲ为例对数字电液系统的组成、系统功能、运行方式和保护控制进行了介绍。

The digital electro -hydraulic con trol systems (DEH -Ⅲ)used for steam turbines at Feng -chen g Power plant are constructed on the basis of WDPF.The structure,functi ons,operating mode and protecting c ircuits of the said system are described in detail.
