摘　　要：针对锅炉主燃料跳闸(MFT)保护系统的逻辑进行分析解读,通过几次触发的MFT保护动作,发现MFT逻辑中存在的问题,通过修改逻辑参数和增加卡板来改善和提高MFT保护系统逻辑的可靠性,做到“保证不拒动,尽可能减少误动”。The logic of the boiler main fuel trip(MFT)protection system was analyzed and interpreted.The problems in the MFT logic were found through several triggered MFT protection actions.And the reliability of logic of MFT protection system is improved and enhanced by modifying the logic parameters and adding cards,to achieve the principle of“guarantee no refusal to move and minimize misoperation”.
