摘要
FSSS作为电站锅炉保护的重要系统广泛应用于大型火力发电机组的锅炉保护中。本文根据国内首台1000MW级二次再热机组——国电泰州二期2×1000MW超超临界二次再热机组的实际情况,对该机组FSSS功能组成和逻辑设计进行总结和分析,归纳了1000MW超超临界二次再热机组FSSS系统的独有特点。通过典型一、二次再热机组的对比,重点探讨了MFT跳闸条件及跳闸后动作的逻辑设计。
As an important protection system of power plant boiler, the FSSS is widely used in large-scale thermal power generating units. Guodian Taizhou Phase 11 is China＇s first 1000MW ultra-supercritical double reheat units. According to this project, the author analyzes and summarizes the functions and logic design of FSSS. This paper describes the unique characteristics of FSSS in 1000MW ultra-supercritical double reheat units. By comparing the typical single reheat unit with the typical double reheat units, the author describes the trip conditions of MFT and the action of MFT after the trip,
