PURPOSE:To obtain a fault judging device for enabling highly efficient verification, by employing knowledge concerning previously registered verify work as a guidance for the verify work. CONSTITUTION:When state change on an electric power system is set in a system state change 1, an inference engine 22 in an electric power system fault judging device 2 is initiated to start judgement. Then inference is proceeded by the inference engine 22 according to control knowledge in a knowledge base 21 in the order of operation principle-erroneous operation or malfunction fault-multiplex fault-erroneous operation fault. Knowledge applying condition in inference process is stored in inference information 23 and a judgement result in an operation principle judgement process is outputted. When a case of fault to be verified is specified in a verification specify 4, a verification mechanism 24 is started. The verification mechanism 24 extracts an identifier to the specified fault case from the inference information and extracts a work sequence of knowledge guidance from a detection knowledge base 25, then a work defined in the knowledge base 25 is performed. |
