Patent ID: 6999903

Claim:
A remote monitoring diagnostic system comprising: a monitoring means for collecting an exhaust gas temperature data of each of plural combustors installed on a gas turbine in a field power plant and for monitoring a combustion state of each of said combustors; a data storage file for storing said exhaust gas temperature data of each of said combustors, said exhaust gas temperature data being collected by said monitoring means; a database which accumulates data relating to error generation causes of past error generation of said combustor of said gas turbine and corresponding operations undertaken in response to said error generation causes of said past error generation; diagnostic means for judging an error generation in said combustor, when a difference in temperature of two exhaust gas temperature datum detected from adjacent combustors is larger than a predetermined value, and for discriminating this error of a temperature detector, when an error is generated in one of said two exhaust gas temperature datum; and a reporting means for sending an error generation cause of said combustor searched from said database and/or information regarding corresponding operations undertaken in response to said error generation cause, in accordance with a result of said judging by said diagnosis means, to a user of said field power plant.
