Abstract: Quick recovery or recovery support of a faulty power generating facility by real time diagnosis such as facility failure diagnosis, supervision for failure symptoms, facility diagnosis by evaluation of performance using databases between said power generating facilities and an operation control system. The operation control system transfers information on operating status and secular characteristic changes of apparatus from power generating facilities or information from operators of selected power generating facilities. The level of a failure of a power generating facility which has a failure is evaluated and repairing information (e.g. recovery procedures, processes, required parts, inventory of the parts, possible failure causes, etc.) is automatically created from repairing information prepared in advance for each evaluation condition. The repairing information is then sent to the operation supporting section of the power generating facility.

Abstract: When an abnormality or a sign of abnormality occurs in an electric power generating facility, an appropriate operating support can be made in a short time.

Abstract: A bed height of a fluidized bed is detected which influences reaction of a fluidized-bed equipment. In the fluidized-bed equipment in which a fluidized particle is put into the vessel, physical properties at a plurality of points within the vessel are measured in a height direction thereof. An interior of the vessel is divided into upper and lower two regions. Physical property distribution curves of the respective regions are found, to find an intersection between the two curves as a bed height. Thus, it is possible to find the bed height of the fluidized bed which influences the reaction of the fluidized-bed equipment. An operating quantity which influences the reaction can be adjusted or regulated accurately.
