Power generation performance analysis system and method
View Patent ↗A system and method is described herein that includes a software-based functionality to assess the relationship between reliability, operational, maintenance and plant betterment activities and to determine the frontier of efficient spending and other measures of performance to achieve a level of reliability that is based on data from units of similar design and performance.
1. A method for providing dynamic comparative operational performance analyses comprising the steps of:
providing a dataset of user-selected data corresponding to a plurality of reference power generating units, the user-selected data comprising a plurality of variables;
determining a geometric center of the dataset;
determining an orientation for the dataset based on the geometric center;
converting the dataset to a predetermined coordinate system based on the geometric center;
categorizing data from the dataset into a plurality of hemispheres and quadrants based on the geometric center;
determining maximum and minimum values of variables in the dataset for frontier curves;
applying a statistical filter to the data from the dataset for each of the plurality of hemispheres and quadrants, generating a filtered data;
combining the filtered data into frontier data groups based on user inputs;
computing maxima and minima for complete frontier curves based on the frontier data groups;
optimizing data envelopment of the complete frontier curves based on the geometric center;
computing complete frontier curve base data values;
converting the complete frontier curve based on the geometric center of the dataset;
displaying a user-selected portion of the complete frontier curve; and
comparing a target unit's data with the user-selected portion of the complete frontier curve.
2. The method of claim 1 , wherein the plurality of variables comprises one or more of unit design characteristics, operations factors, and maintenance and plant betterment data, or combinations thereof.
3. The method of claim 1 , wherein the target unit is a reference generating unit.
4. The method of claim 1 comprising the additional step of:
displaying a linear trend of the dataset.
5. A system comprising:
a server, comprising:
a processor, and
a storage subsystem;
a database stored by the storage subsystem comprising:
a plurality of data corresponding to reference power generating units; and
a computer program stored by the storage subsystem, when executed causing the processor to:
select a dataset from the plurality of data corresponding to user selection criteria;
determine a complete frontier curve based on the dataset; and
compare data of a target unit with a portion of the complete frontier curve.
6. The system of claim 5 , wherein the computer program, when executed further causes the processor to display a linear trend of the dataset.
7. The system of claim 5 , wherein the target unit is a reference generating unit.
8. A system comprising:
a first server, comprising:
a processor, and
a first storage subsystem;
a second server, comprising:
a second storage subsystem;
a database stored by the second storage subsystem comprising:
a plurality of data corresponding to reference power generating units; and
a computer program stored by the first storage subsystem, when executed causing the processor to:
select a dataset from the plurality of data corresponding to a user selection;
determine a complete frontier curve based on the dataset; and
compare data of a target unit with a portion of the complete frontier curve.
9. The system of claim 8 , wherein the computer program, when executed further causes the processor to display a linear trend of the dataset.
10. The system of claim 8 , wherein the target unit is a reference generating unit.
