Abstract

A monitoring system is disclosed for acquiring output activity, utilization capacity and/or effluent data from an facility on a facility-by-facility and/or an industry-by-industry basis. The system is designed to generate a plant and/or industry output activity database that is updated on a continuous, near continuous, periodic and/or intermittent basis so that subscribers are apprised of changes in plant or overall industry output. A clearing house is also disclosed for distributing the acquired data to subscribers to aid in analyzing, predicting trends, pricing, maintaining, adjusting, minimizing, and/or maximizing individual plant or overall industry output.

Claims

1. A method for monitoring, determining, and outputting at least one of plant output activity and capacity utilization of at least one power generating plant connected to a power grid comprising the steps of:

acquiring thermal images of at least one of one or more stack effluent plumes produced by the at least one power generating plant connected to the power grid using at least one thermal imaging camera,

storing the acquired thermal images of the at least one of the one or more stack effluent plumes with at least one processing unit,

transmitting the stored thermal images of the at least one of the one or more stack effluent plumes from the at least one processing unit to a central processing center having at least one processor,

scanning the thermal images of the at least one of the one or more stack effluent plumes with the at least one processor to identify pixels within the thermal images containing more than at least one of a background pixel intensity and a threshold pixel intensity and thereby define active regions within the transmitted thermal images,

associating pixel intensities within the active regions of the thermal images with the at least one of plant output activity and capacity utilization supplied by the at least one power generating plant to the power grid using the at least one processor, and

transmitting from the central processing center to at least one of one or more user devices information concerning the at least one of plant output activity and capacity utilization supplied to the power grid based on the associated pixel intensities within the active regions of the thermal images.

2. The method of claim 1, further comprising the step of:

prior to the step of associating pixel intensities, correcting the pixel data to compensate for existing environmental factors using a data processing subsystem.

3. The method of claim 2, further comprising the steps of:

accumulating the information concerning the at least one of plant output activity and capacity utilization supplied to the power grid using an accumulation subsystem and

determining trends using a trend subsystem from the accumulated information concerning the at least one of plant output activity and capacity utilization supplied to the power grid.

4. The method of claim 3, further comprising the step of:

producing a report using a report subsystem evidencing the at least one of plant output activity and capacity utilization over time.

5. The method of claim 1, wherein the at least one of the one or more stack effluent plumes includes a plurality of stack effluent plumes, the at least one power generating plant includes a plurality of power generating plants, and the at least one thermal imaging camera includes a plurality of thermal imaging cameras, and wherein the step of acquiring thermal images includes acquiring thermal images of the plurality of the stack effluent plumes produced by the plurality of the power generating plants connected to the power grid using the plurality of thermal imaging cameras.

6. The method of claim 5, wherein the step of transmitting from the central processing center includes transmitting the information concerning the at least one of plant output activity and capacity utilization supplied to the power grid by each of the plurality of the power generating plants based on the associated pixel intensities within the active regions of the thermal images.

7. The method of claim 1, wherein the step of associating pixel intensities includes comparing the pixel intensities within the active regions of the thermal images against a baseline of previously acquired data, and further comprising a step of predicting disruptions in the power grid based on the comparison.

8. The method of claim 7, wherein the previously acquired data includes data from the stored thermal images collected over time.

9. The method of claim 7, wherein the step of transmitting from the central processing center includes transmitting information concerning the predicted disruptions from the central processing center to the at least one of the one or more user devices.

10. The method of claim 1, wherein the step of transmitting from the central processing center includes transmitting information concerning the at least one of plant output activity and capacity utilization of the at least one power generating plant to a clearinghouse where the information is accessible to a plurality of users in a form that reveals trends.

11. The method of claim 1, further comprising a step of connecting the at least one thermal imaging camera to the power grid using a power conditioning unit.

12. The method of claim 2, wherein the step of correcting includes correcting the pixel data to compensate for weather conditions using a data processing subsystem.

13. The method of claim 12, wherein the step of correcting includes applying a correction factor to pixels data in the active regions.

14. A method for monitoring, determining, and outputting at least one of plant output activity and capacity utilization of at least one power generating plant connected to a power grid comprising the steps of:

acquiring thermal images of at least one of one or more stack effluent plumes produced by the at least one power generating plant connected to the power grid using at least one thermal imaging camera,

storing the acquired thermal images of the at least one of the one or more stack effluent plumes with at least one processing unit,

transmitting the stored thermal images of the at least one of the one or more stack effluent plumes from the at least one processing unit to a processor,

scanning the thermal images of the at least one of the one or more stack effluent plumes with the processor to identify pixels within the thermal images containing more than at least one of a background pixel intensity and a threshold pixel intensity and thereby define active regions within the transmitted thermal images,

associating pixel intensities within the active regions of the thermal images with the at least one of plant output activity and capacity utilization supplied by the at least one power generating plant to the power grid using the processor, and

transmitting from the processor to at least one of one or more user devices information concerning the at least one of plant output activity and capacity utilization supplied to the power grid based on the associated pixel intensities within the active regions of the thermal images.
