FSSS系统MFT硬保护逻辑优化和改进

MFT Hard Protection of the FSSS System based on Logic Optimization and Improvement

本文通过对FSSS系统问题引起的机组异常事件的分析,说明完善FSSS系统的重要性,结合台州发电厂DCS改造项目中的FSSS系统设计方案为实例,提出了通过电源冗余设计以及软件冗余设计等优化FSSS系统的方式和方法;来达到为机组可靠运行提供保证的有力措施。

This paper discusses abnormal unit events caused by the FSSS system, and illustrates the importance of improving FSSS system. Take a DCS project in Taizhou power plant as an example,we optimize the FSSS system by power supply redundancy and software redundancy to achieve reliable operation.
