Vibration fault diagnosis of steam turbine generating unit based on expert system

It is very important to diagnose the fault based on the steam turbine vibration signal of the thermal power plant timely and effective.An expert system is a computer program designed to modeling the problem solving capacity of human experts.In this paper we designed a Turbine Fault Diagnosis Expert System which is to identify unit operational state signs and to deduce the reason for unit faults according to the recorded data from practical locale.
