Electric power generating facility operation remote supporting method and electric power generating facility operation remote supporting system

An electric power facility operation remote supporting method for remotely supporting operation of an electric power generating facility by monitoring and diagnosing operating states of electric power generating facilities installed at a plurality of distributed places from a place different from the places of said facilities, wherein

• information including operating states and time- varying characteristics of components of a concerned electric power generating facility is transmitted to a monitoring person side under a condition pre-contracted with a manager of said concerned electric power generating facility, and
• an accounting contract corresponding to a degree of technical difficulty in regard to the abnormality corrective action corresponding to contents of the contract with the manager of said concerned electric power generating facility is made with the manager of said concerned electric power generating facility when a dynamic trend of said concerned electric power generating facility is calculated on the basis of the transmitted information and it is judged that a sign of abnormality or an abnormality occurs in the facility, a load changing operation analysis by an operating characteristic evaluation tool which is a combination of a simulator and a control logic which are tuned so as to simulate characteristics of said concerned electric power generating facility is performed, and recommended control set values obtained thereby are offered to a section in charge of operation of said concerned electric power generating facility when an analysis result obtained by said load changing operation analyzing function falls within an allowable range.

An electric power facility operation remote supporting method for remotely supporting operation of an electric power generating facility, the method comprising the steps of:

• presetting abnormality corrective-action data corresponding to a plural kinds of abnormality or abnormal sign data in regard to said electric power generating facility;
• presetting servicing modes corresponding to said abnormality corrective-action data;
• judging an abnormality or a sign of abnormality of said electric power generating facility based on at least one of operating state information of said electric power generating facility and information on time-varying characteristics of electric power facility components;
• and
• setting a servicing mode based on information judging an abnormality or a sign of abnormality and said preset abnormality corrective-action data corresponding to abnormality or abnormal sign data and said preset servicing modes corresponding to said abnormality corrective-action data when said abnormality or said sign of abnormality occurs in said electric power generating facility.

An electric power facility operation remote supporting system for remotely supporting operation of an electric power generating facility by monitoring and diagnosing operating states of electric power generating facilities installed at a plurality of distributed places from a place different from the places of said facilities, which comprises:

• means for transmitting at least one of information on operating states and time-varying characteristics of components from said electric power generating facilities to said system;
• means for processing and diagnosing the information obtained by said means for transmitting information;
• and
• means for starting a prepared abnormality corrective-action task corresponding to a degree of abnormality when it is judged that a sign of abnormality occurs in the facility based on the information from said means for transmitting information, and transmitting information generated thereby to a section in charge of operation of said electric power generating facility,
• wherein when a sign of abnormality occurs in said electric power generating facility and can be solved by changing a set value in a control unit associating with said facility, the information on an operating state and the time-varying characteristics of the components from said electric power generating facility is input to a simulator which reproduce characteristics of the actual facility using information on test operation of said concerned facility performed in advance and normal operating information, and a control condition is improved based on a set value changing guideline obtained from a sensitivity analysis in advance, and then the improved information is offered to the manager of said facility.

An electric power facility operation remote supporting system for remotely supporting operation of an electric power generating facility, which comprises:

• a database for storing abnormality corrective-action data corresponding to data of a plurality of abnormalities or signs of abnormality in regard to said electric power generating facility;
• a database for storing service modes corresponding to said abnormality corrective-action data;
• means for judging an abnormality or a sign of abnormality of said electric power generating facility based on at least one of information on an operating state of said electric power generating facility and information on time-varying characteristic of components of said electric power generating facility;
• and
• means for setting a service mode based on information judging an abnormality or a sign of abnormality when the abnormality or the sign of abnormality occurs in said electric power generating facilities, said stored abnormality corrective-action data corresponding to data of the abnormalities or the signs of abnormality, and said stored service modes corresponding to said abnormality corrective-action data.
