Aiming at the low accuracy of current fuzzy diagnosis system,the paper analyses the main cause of the low accuracy,and then proposes a new diagnosis strategy based on the varying- weight model of com prehensive evaluation and expanded m embership function for faultdiagnosis.The new diagnosis strategy has som e essential difference from conventional system s in evaluation m odel and definition of fuzzy m embership functions.Based on the new diagnosis strategy,a fault diagnosis system for2 0 0 MW turbo- generator set is designed and program med.The application results prove that the original idea is effective in solving practical problem s.
