Abstract

A method for determining whether an operational metric representing the performance of a target machine has an anomalous value is provided. The method includes collecting operational data from at least one machine, and calculating at least one exceptional anomaly score from the obtained operational data.

Claims

1. A method for determining whether an operational metric representing the performance of a target machine has an anomalous value, the method comprising:

collecting operational data from at least one machine; and

calculating at least one exceptional anomaly score from said operational data.

2. The method as defined in claim 1, said method comprising:

creating at least one alert, said at least one alert based on, at least one of, said at least one exceptional anomaly score and said operational data.

3. The method as defined in claim 1, said method comprising:

creating at least one heatmap, said at least one heatmap visually illustrating at least one of, said at least one exceptional anomaly score and said operational data.

4. The method as defined in claim 1, wherein said target machine is a turbomachine selected from the group comprising:

a compressor, a gas turbine, a hydroelectric turbine, a steam turbine, a wind turbine, and a generator.

5. The method as defined in claim 4, wherein the step of collecting operational data further comprises:

collecting operational data from a plurality of machines, each of said machines being similar in at least one of configuration, capacity, size, output and geographic location.

6. The method as defined in claim 4, wherein subsequent to the calculating at least one exceptional anomaly score step, said method comprises:

creating at least one sensitivity setting for said at least one exceptional anomaly score, said at least one sensitivity setting defining a percentage of said operational data to be monitored.

7. The method as defined in claim 2, further comprising aggregating performed prior to said creating at least one alert step, said aggregating comprising:

aggregating said operational data, said operational data comprised of a plurality of individual data readings taken over various time intervals.

8. The method as defined in claim 3, wherein said at least one heatmap further comprises:

a two dimensional display comprised of multiple cells, said two dimensional display having at least one column and at least one row, wherein said multiple cells can display multiple colors, said multiple colors indicating, at least one of high, low, and normal ranges for said at least one exceptional anomaly score and said operational data.

9. A method for determining whether an operational metric representing the performance of a target machine has an anomalous value, the method comprising:

collecting operational data from at least one machine;

calculating at least one exceptional anomaly score from said operational data;

aggregating said operational data;

creating at least one sensitivity setting for said at least one exceptional anomaly score;

creating at least one alert, said at least one alert based on, at least one of, said at least one exceptional anomaly score and said operational data; and

creating at least one heatmap, said at least one heatmap visually illustrating at least one of said at least one exceptional anomaly score and said operational data.

10. The method as defined in claim 9, wherein said target machine is a turbomachine selected from the group comprising:

a compressor, a gas turbine, a hydroelectric turbine, a steam turbine, a wind turbine, and a generator.

11. The method as defined in claim 9, wherein the step of collecting operational data further comprises:

collecting operational data from a plurality of machines, each of said machines being similar in at least one of configuration, capacity, size, output and geographic location.

12. The method as defined in claim 9, wherein said at least one sensitivity setting defines a percentage of said operational data to be monitored.

13. The method as defined in claim 9, wherein the operational data used in said aggregating step is comprised of a plurality of individual data readings taken from at least one machine over various time intervals.

14. The method as defined in claim 9, wherein said at least one heatmap further comprises:

a two dimensional display comprised of multiple cells, said two dimensional display having at least one column and at least one row, wherein said multiple cells can display multiple colors, said multiple colors indicating, at least one of, high, low and normal ranges for said at least one exceptional anomaly score and said operational data.

15. A method for determining whether an operational metric representing the performance of a target machine has an anomalous value, the method comprising:

collecting operational data from at least one machine;

calculating at least one exceptional anomaly score from said operational data;

aggregating said operational data;

creating at least one sensitivity setting for said at least one exceptional anomaly score;

creating at least one alert, said at least one alert based on, at least one of, said at least one exceptional anomaly score and said operational data; and

creating at least one heatmap, said at least one heatmap visually illustrating at least one of said at least one exceptional anomaly score and said operational data.

16. The method as defined in claim 15, wherein said target machine is a turbomachine selected from the group comprising:

a compressor, a gas turbine, a hydroelectric turbine, a steam turbine, a wind turbine, and a generator.

17. The method as defined in claim 16, wherein the step of collecting operational data further comprises:

collecting operational data from a plurality of machines, each of said machines being similar in at least one of configuration, capacity, size, output and geographic location.
