Abstract

The present invention is directed to a power transfer system and method for utilizing the electrical power generated by a powered vehicle, such as a locomotive. The power transfer system comprises an electromotive machine configured to generate electrical energy on the powered vehicle and an electrical system located outboard from the powered vehicle, which is configured to receive electrical energy. Interface equipment is provided, which is electrically coupled to the electromotive machine and the electrical system, to transfer electrical energy from the electromotive machine to the electrical system.

Claims (34)

1. A method for utilizing electrical energy generated by a powered vehicle comprising:

generating electrical energy via an electromotive machine on the powered vehicle; and

transferring at least a portion of the electrical energy to an electrical system located outboard of the powered vehicle via interface equipment electrically coupled to the electromotive machine and the electrical system;

wherein the electrical system is an electric utility, and further comprising generating revenue over a period of time based on the amount of electrical energy transferred to the electric utility.

2. A method for utilizing electrical energy generated by a powered vehicle comprising:

generating electrical energy via an electromotive machine on the powered vehicle; and

transferring at least a portion of the electrical energy to an electrical system located outboard of the powered vehicle via interface equipment electrically coupled to the electromotive machine and the electrical system;

wherein the electrical energy is generated during self-load testing of the powered vehicle.

3. The method of claim 1 , wherein all of the electrical energy generated by the electromotive machine is transferred to the electrical system.

4. The method of claim 1 , wherein at least a portion of the electrical energy generated by the electromotive machine is transferred to the electrical system and at least a portion of the electrical energy generated by the electromotive machine is dissipated by the powered vehicle.

5. A method for utilizing electrical energy generated by a powered vehicle comprising:

generating electrical energy via an electromotive machine on the powered vehicle; and

transferring at least a portion of the electrical energy to an electrical system located outboard of the powered vehicle via interface equipment electrically coupled to the electromotive machine and the electrical system;

wherein the electromotive machine is electrically coupled to a resistive grid onboard the powered vehicle, and wherein the transferring of at least a portion of the electrical energy comprises bypassing at least a portion of the electrical energy by the resistive grid onboard the powered vehicle.

6. The method of claim 1 , wherein the transferring of the electrical energy further comprises converting a rectified electrical energy from the electromotive machine to AC electrical energy.

7. The method of claim 6 , further comprising adjusting a parameter of the AC electrical energy, wherein the parameter is selected from the group consisting of voltage, current, and frequency.

8. The method of claim 1 , further comprising electrically coupling the interface equipment to a power bus on the powered vehicle.

9. The method of claim 1 , further comprising adjusting a power output generated by the electromotive machine based upon an amount of electricity desired to be transferred to the electrical system.

10. The method of claim 1 , further comprising modifying the electrical energy from the electromotive machine into a predetermined form for the electrical system.

11. The method of claim 1 , wherein the interface equipment is located outboard from the powered vehicle.

12. A power transfer system for a powered vehicle comprising:

an electromotive machine configured to generate electrical energy on the powered vehicle;

an electrical system located outboard from the powered vehicle configured to receive a quantity of electrical energy;

interface equipment electrically coupled to the electrical system and configured to transfer electrical energy from the powered vehicle to the electrical system; and

a controller configured to determine an amount of electrical energy transferred to the electrical system over a period of time and configured to transmit information relating to the generation of revenue based on the amount of electrical energy transferred to the electrical system.

13. The power transfer system of claim 12 , wherein the interface equipment further comprises a DC/DC converter and a three-phase inverter for converting the electrical energy to three-phase AC electrical energy.

14. The power transfer system of claim 13 , wherein the interface equipment further comprises at least one second controller for measuring a voltage and a current on at least one of the DC/DC converter and the three-phase inverter and for regulating an amount of electrical energy transferred from the electromotive machine to the electrical system.

15. The power transfer system of claim 14 , further comprising at least one third controller for regulating an output of electrical energy from the electromotive machine, wherein the at least one second controller and the at least one third controller are in communication with one another, and wherein the at least one third controller is onboard the powered vehicle.

16. The power transfer system of claim 15 , wherein the at least one third controller is configured for regulating a powered vehicle notch setting on the powered vehicle corresponding to an electrical energy output of the electromotive machine.

17. The power transfer system of claim 12 , wherein the interface equipment further comprises power conditioning equipment for selectively modifying the electrical energy from the electromotive machine into a predetermined form for the electrical system.

18. The power transfer system of claim 12 , wherein the interface equipment is located outboard from the powered vehicle.

19. A method for utilizing electrical energy generated by a powered vehicle comprising:

receiving, at an electrical system located outboard of the powered vehicle, electrical energy generated by an electromotive machine on the powered vehicle; and

determining revenue information based on an amount of said electrical energy received at the electrical system for use by the electrical system, wherein the revenue information relates to a value of said amount of electrical energy.
