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 a power generating plant connected to a power grid and outputting data regarding at least one of plant output activity and capacity utilization supplied to the power grid comprising the steps of:

positioning an imaging subsystem having at least one infrared camera in view of at least one of one or more stacks of the power generating plant and effluent plumes produced by the power generating plant connected to the power grid,

capturing, with the at least one infrared camera of the imaging subsystem, images of the at least one of the one or more stacks and effluent plumes,

converting, with at least one processor, the captured images of the at least one of the one or more stacks and effluent plumes into electronic image data representing the captured images of the at least one of the one or more stacks and effluent plumes,

defining, with the at least one processor, one or more active regions within the electronic image data corresponding to the at least one of the one or more stacks and effluent plumes using an analysis subsystem,

comparing, with the at least one processor, the electronic image data extracted from the active regions against a baseline of previously acquired image data from active regions of earlier captured images of the at least one of the one or more stacks and effluent plumes,

converting, with the at least one processor, the electronic image data into output active regions density data as measures of at least one of the plant output activity and capacity utilization supplied to the power grid,

accumulating, with the at least one processor, the measures of the at least one of the plant output capacity and capacity utilization supplied to the power grid over a time period using an accumulation subsystem, wherein the accumulating over the time period is one of continuous accumulating or accumulating for a shorter period of time than the time period at regular intervals throughout the time period,

establishing, with the at least one processor, the baseline based on an average value of the measures acquired over the time period,

predicting, with the at least one processor, disruptions in the power grid based on changes in the measures acquired over the time period, and

reporting to end user devices, with the at least one processor, the measures of the at least one of the plant output activity and capacity utilization supplied to the power grid to inform end users of a contribution of the power generating plant to the power grid.

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

correcting the electronic image data for existing environmental factors using a data processing subsystem, wherein the data processing subsystem extracts pixels associated with the active regions in the captured images, determines a subset of the extracted pixels that are on and have an intensity greater than a background or set threshold intensity, and the data processing subsystem applies one or more correction factors for weather conditions to the subset of the extracted pixels and wherein the correction factors are determined from previously captured images accumulated over time or acquired under different weather conditions at constant plant output.

3. The method of claim 1, wherein the step of positioning includes locating the at least one infrared camera at a distance from the at least one of the one or more stacks and effluent plumes between about 100 meters and about 5 kilometers.

4. The method of claim 1, wherein the step of reporting includes reporting the measures of the at least one of the plant output activity and capacity utilization supplied to the power grid to an industry clearinghouse, where members of the industry clearinghouse are provided with access to the measures of the at least one of the plant output activity and capacity utilization.
