Abstract

A method of determining an operation of at least one of a plurality of generators in a power generation system. The method includes identifying a system parameter that is related to operation of the power generation system; and determining which of the plurality of generators to operate to minimize fuel consumption of the power generation system based on the system parameter. Other methods include identifying a system parameter that is related to operation of the power generation system; and determining which of the plurality of generators to operate by optimizing an operating variable of the power generation system based on the system parameter.

First claim

What is claimed is:

1. A method of determining an operation of at least one of a plurality of generators in a power generation system comprising:
identifying a system parameter that is related to operation of the power generation system using a controller; and
determining which of the plurality of generators to operate to minimize fuel consumption of the power generation system based on the system parameter, wherein determining which of the plurality of generators to activate or deactivate to minimize fuel consumption of the power generation system based on the system parameter includes calculating expected fuel consumption for each possible permutation of active generators in the plurality of generators based on the system parameter.

2. The method of claim 1 wherein calculating expected fuel consumption for each possible permutation of active generators in the plurality of generators includes calculating fuel consumption for each generator in the plurality of generators.

3. The method of claim 1 wherein calculating fuel consumption for each possible permutation of active generators in the plurality of generators includes obtaining data from fuel efficiency curves that indicate fuel consumption for each possible permutation of active generators in the plurality of generators.

4. The method of claim 1 wherein calculating fuel consumption for each possible permutation of active generators in the plurality of generators includes measuring fuel consumption for each generator in the plurality of generators.

5. The method of claim 1 wherein measuring fuel consumption for each generator in the plurality of generators includes storing fuel consumption data and utilizing fuel consumption data in determining which of the plurality of generators to activate or deactivate in order to minimize fuel consumption of the power generation system.

6. A generator management system comprising:
a plurality of generators that are adapted to supply power to a load; and
a control system that operates the plurality of generators, wherein the control system determines which of the plurality of generators to activate or deactivate based on a system parameter in order to minimize fuel consumption of the power generation system, wherein the control system calculates fuel consumption for each possible permutation of active generators in the plurality of generators.

7. The generator management system of claim 6 further comprising a server that is connected to the control system via a network, wherein at least one of the control system and the server determines which of the plurality of generators to activate or deactivate based on the system parameter in order to minimize fuel consumption of the power generation system.

8. The generator management system of claim 6 wherein the control system includes a generator controller that controls operation of at least one of a plurality of generators.

9. The generator management system of claim 6 wherein the control system anticipates the load that is to be supplied with power by the plurality of generators.

10. The generator management system of claim 6 wherein the control system maintains a minimum load that is set by local emissions standards on at least one of the plurality of generators.

11. The generator management system of claim 6 wherein the control system measures the fuel consumption of each possible permutation of active generators in the plurality of generators.

12. The generator management system of claim 6 wherein at least one generator in the plurality of generators is different in size, fuel efficiency or fuel type than the other generators in the plurality of generators.

13. The generator management system of claim 6 wherein the control system includes a plurality of generator controllers that are each configured to control at least one generator.
