【Abstract】 This paper presents an artificial intellectual protection scheme for power transformer.The knowledge base is built based on production rules,and the inference engine is set up based onboth exact logic and fuzzy logic. Two fuzzy functions are introduced to distinguish exciting in-rush from interal faults. A probable hardware structure is also given in the paper. The real-timeproblem of intellectual protective relays is discussed at the end.更多还原
