大型火电机组汽轮机保护系统的探讨

Discussion of Protection System of Large Scale Thermal Power Unit Steam Turbine

介绍了汽轮机保护系统常见的两种实现方式,一是在分散控制系统(DCS)中实现汽轮机保护系统,二是运用可编程控制器(PLC)实现汽轮机保护系统。对这两种方式进行了分析比较,并根据工程调试实际提出了优化汽轮机保护系统的建议。

This paper introduces two common ways to implement protection system of steam turbine, one is to fulfil it inDistrubuted Control System （DCS） and the other is to use Programmable Logic Controller （PLC）. By analyzing and comparing these two ways. this paper puts forward proposals to optimize protection system of steam turbine according to engineering test practice.
