    Abstract: Introduction was made to the unit trip accident caused by the UNITROL6800 excitation system fault. The accident cause was analyzed and the excitation system was verified. This paper gave the corresponding rectification and reform program and carried out anti-interference reform. The actual operation shows that this scheme raises the reliability of UNITROL6800 system and can eliminate adverse consequences caused by the system misoperation effectively.
    Key words: excitation system; maloperation; pulse blocking; reliability
