Abstract: A system and method for estimating the impact of compressor fouling in a combined cycle power block. The current performance of the combined cycle power block is determined and normalized to one or more reference conditions. A baseline performance of a gas turbine of the combined cycle power block is also determined. A predicted performance of the combined cycle power block is then determined by substituting the baseline performance of the gas turbine for the current performance of the gas turbine. A recoverable impact to the combined cycle power block due to compressor fouling is then determined by subtracting the normalized current performance from the predicted performance and a recoverable impact to the fuel consumption of the combined cycle power block is determined from the recoverable impact.

Abstract: A computer-implemented method for modeling and/or improving operational performance of an energy system includes providing a graphical user interface configured to allow a user to manipulate equipment icons into an energy system model representation, using modular, piece-wise linear equipment models to simulate non-linear behavior of equipment represented by the manipulated equipment icons to solve an energy system model represented by the manipulation, and displaying a solution of the energy system model.

Abstract: Methods and systems for operating combined cycle electrical generating plants is provided. The method includes simulating the electrical power plant performance, simulating the steam utilizing process plant performance, parameterizing plant equipment and plant performance using the power plant and process plant simulation results, and solving parameterized simultaneous equations and constraints with an objective function to determine parameter settings that facilitate enhancing an efficiency of the combined cycle electrical generating/steam-utilizing process plant.

Abstract: Particle size analysis is carried out in a cuvette traversed by a plurality of vertically spaced light curtains which, because of the spacing, allows precision mesurements to be obtained without problems arising from the scanning of a sedimentation cell.
