| 摘 要： | 主汽温度10 min下降50℃保护是汽轮机ETS保护系统的1项重要内容。现代装机在100 MW以上且具有DCS控制系统的机组都很容易实现此项保护功能,通过对主汽温度信号的测量以及DCS系统控制组态程序对信号的质量筛选、逻辑运算、保护输出来实现。正确的组态逻辑和成熟、稳定的外部回路,保证了机组在主汽温度突然下降情况下实现保护正确动作。

| Abstract: | The protection of main steam temperature descending 50C is an important content of the Generator ETS protection system. Modern Generators above 100MW with DCS control system all realize the function very easily, it realizes by monitoring temperature signal trip and chosing of quality to signal, logic architecture, protecting driving output. It guarantees that the protecting of main steam temperature descending 50C triggers correctly for Perfectconfiguration of profecting and reliable operation. |
