摘要

为了提高发电厂单点温度保护系统的可靠性

提出了采用温度变化率坏点闭锁逻辑和延时、高高限、低低限坏点闭锁逻辑2种容错逻辑设计方案

并对这2种方案进行了比较。采用温度变化率坏点闭锁逻辑方案

进行合适的参数设置尤为重要;延时、高高限、低低限坏点闭锁逻辑方案的参数设置较简单。

Abstract

In order to enhance the reliability of single point temperature protection sytem in power plants

two schemes of fault-tolerant logic design have been put forward

the one adopts a blocking logic of bad points in temperature changing rate

the other one adopts blocking logic of bad points in time-delay

high higher-limit

and low lower-limit.The advantages and disadvantages of said two design schemes have been compared.For the first scheme

the setting of suitable parameters is more important

but for the second scheme

the setting of parameters is comparatively simple.
