Abstract:

A method and apparatus for operating a production system that includes a plurality of production facilities is provided. The method includes receiving, in real-time, for each facility, cost data for a first resource used by each respective facility to produce an output, receiving, in real-time, for each facility, cost data for a second resource used by each respective facility to produce the output, determining, in real-time; an automated incremental cost curve for the system based on a level of production of each facility and the received resource cost data, and determining a production output target for each production facility to achieve an optimum production system output based on the real-time incremental cost curves. The system includes at least one production facility that includes a software code segment programmed to determine, in real-time, an incremental cost of a first resource based on a level of production of each respective facility.

International Classification:

G05D 11/00

US Classification:

700286000

Abstract:

A method of generating NOx curves over a range of load points includes obtaining current measurements from a respective sensor and validating the current measurements. A plurality of input curves are generated using predefined inputs for each load point. The plurality of input curves include a first set point curve and a second set point curve, where the second setpoint curve includes the first setpoint curve offset with the current measurements. A plurality of NOx curves are generated including a design curve, an adjusted design curve, and a NOx generation curve created by a neural model. The second setpoint curve is passed through the neural model to derive the NOx generation curve. After validating the NOx generation curve and adjusted design curve, one of the plurality of NOx curves is outputted.

International Classification:

G06F 17/00

US Classification:

705400000

Abstract:

A method of generating emission curves over a range of load points includes obtaining current measurements from a respective sensor. The current measurements are validated and a plurality of emission curves using predefined inputs for each load point are generated. The plurality of emission curves includes an emission design curve and a corresponding real time incremental emission curve. Each corresponding real time incremental emission curve and emission design curve are validated to generate a validated emission curve. An incremental emission cost curve using each validated emission curve for each type of emission is generated. Each incremental emission cost curve is summed if there is more than one incremental emission cost curve.

US Classification:

705412000, 700291000

Abstract:

Methods, apparatus, and articles of manufacture such as software media for creating projected power production data are described herein. The method may comprise storing historical heat rate data for at least one power generation unit in a historical heat rate database. The method may also comprise retrieving the historical heat rate data from the database for a selected time interval and creating a projected cost curve and/or a projected price curve for a future time interval based on the historical heat rate data.

Abstract:

Methods, apparatus, and articles of manufacture such as software media for creating projected power production data are disclosed. The method may comprise storing historical heat rate data and historical process information for at least one power generation unit in a historical heat rate database. The method may also comprise retrieving the historical heat rate data from the database for a selected time interval and correcting the historical rate data using correction factors which may be based on differences between the historical process information and projected process information; and creating a projected cost or a projected price for a future time interval based on the retrieved historical heat rate data.

Abstract:

An improved combustion system for an internal combustion engine is disclosed wherein a rich air/fuel mixture is furnished at high pressure to one or more jet plume generator cavities adjacent to a cylinder and then injected through one or more orifices from the cavities into the head space of the cylinder to form one or more turbulent jet plumes in the head space of the cylinder prior to ignition of the rich air/fuel mixture in the cavity of the jet plume generator. The portion of the rich air/fuel mixture remaining in the cavity of the generator is then ignited to provide a secondary jet, comprising incomplete combustion products which are injected into the cylinder to initiate combustion in the already formed turbulent jet plume. Formation of the turbulent jet plume in the head space of the cylinder prior to ignition has been found to yield a higher maximum combustion pressure in the cylinder, as well as shortening the time period to attain such a maximum pressure.
