Abstract

A system having an efracking trailer, a first low efficiency efracking six mega volt ampere (MVA) transformer attached to the efracking trailer; an efracking transformer core inside of the efracking transformer; and a cooling fan attached to the efracking trailer, wherein the cooling fan forces chilled air into the efracking transformer core.

Claims (48)

1. An electric fracking (efracking) power supply system comprising:

an efracking trailer, wherein the trailer is smaller and lighter than a trailer for a high efficiency transformer trailer, configured to make the efracking trailer maneuverable in an oil filed, wherein, a fifty foot, five axel trailer required for a standard electrical transformer that weighs, 5,000 pounds is reduced to a twenty-five foot, two axel trailer the weighs only 1,700 pounds;

a 70 percent efficiency efracking six mega volt ampere (MVA) transformer attached to the efracking trailer, wherein the efracking transformer is one third the volume, size, and weight of a 95 percent efficiency electrical 6 MVA transformer;

an efracking transformer core inside of the efracking transformer; and

a cooling fan attached to the efracking trailer, wherein the cooling fan forces chilled air into the efracking transformer core.

2. The electric fracking power supply system of claim 1 , further comprising:

a power utility grid attached to an input of the efracking transformer; and

an electrical fracking equipment attached to an output of the efracking power supply system.

3. The electric fracking power supply system of claim 1 , wherein number 18 American wire gauge transformer windings are wound onto the efracking transformer core.

4. The electric fracking power supply system of claim 1 , further comprising: air gaps formed in the efracking transformer core, wherein the cooling fan attached to the efracking trailer forces chilled air into the air gaps formed in the efracking transformer core.

5. The electric fracking power supply system of claim 1 , wherein the cooling fan is a high horse power fan that blows outdoor ambient air at 45 degrees centigrade onto the electric fracking core at 175 degrees centigrade.

6. The electric fracking power supply system of claim 1 , further comprising:

an electric utility grid that supplies alternating current to the electric fracking trailer.

7. The electric fracking power supply of claim 6 , further comprising:

a diode rectifier that corrects for voltage droop created by the electric fracking transformer.

8. The electric fracking power supply system of claim 1 , further comprising:

a second low efficiency efracking transformer; and

a processor attached to the first and second efracking transformers, the processor further comprising a non-transitory computer readable medium containing a computer program comprising instructions that are executed by the processor.

9. The electric fracking power supply system of claim 8 , wherein

the computer program further comprises a linear program that adjusts the output of the first and second efracking transformers based on a load attached to the first and second efracking transformers.

10. The electric fracking power supply system of claim 8 , wherein

the computer program further comprises a linear program that adjusts the output of the cooling fans attached to the first and second efracking transformers based on a load attached to the first and second efracking transformers.

11. The electric fracking power supply system of claim 1 , further comprising:

a processor in data communication with a non-transitory computer readable medium, attached to the electric fracking power supply system, the electric power supply system

comprising a first and second efracking transformer, a first and second cooling fan that forces chilled air into the first and second efracking transformer, a first and second inverter attached to the first and second efracking transformer;

a computer program comprising instructions stored in the non-transitory computer readable medium that are executed by the processor, the computer program comprising,

instructions to determine a current system load serviced the first efracking transformer and the second efracking transformer provided from the efracking power supply system;

instructions to determine a current operating state for the first and second efracking transformers, a speed of the first and second cooling fan, a temperature of the first and second efracking transformer, and a temperature of the first and second cooling fans;

instructions to determine a new operating state for the first and second efracking transformers, a speed of the first and second cooling fan, a temperature of the first and second efracking transformer, and a temperature of the first and second cooling fans; and

instructions to replace the current operating state for the first and second efracking transformer, a speed of the first and second cooling fan, a temperature of the first and second efracking transformer, and a temperature of the first and second cooling fans to the new operating state for the first and second efracking transformer, a speed of the first and second cooling fan, a temperature of the first and second efracking transformer, and a temperature of the first and second cooling fans.

12. The electric fracking power supply system of claim 11 , wherein the operating state comprises a load on the first and second efracking transformer, a speed of the first and second cooling fan, a temperature of the first and second efracking transformer, and a temperature of the first and second cooling fans.

13. The electric fracking power supply system of claim 12 , wherein the computer program is a linear program.

14. The electric fracking power supply system of claim 12 , wherein the computer program is an expert system.

15. The electric fracking power supply system of claim 12 , wherein the computer program is a neural network.

16. A non-transitory computer readable medium containing instructions that are executed by a processor in data communication with the non-transitory computer readable medium to control an efracking power supply system, comprising instructions stored in the non-transitory computer readable medium that are executed by the processor, the instructions comprising,

instructions to determine a current system load serviced by efracking power supply system first efracking transformer and the second efracking transformer provided from the efracking power supply system;

instructions to determine a current operating state for the first and second efracking transformer, a speed of the first and second cooling fan, a temperature of the first and second efracking transformers, and a temperature of the first and second cooling fans;

instructions to determine a new operating state for the first and second efracking transformer, the speed of the first and second cooling fan, the temperature of the first and second efracking transformer, and the temperature of the first and second cooling fans; and

instructions to replace the current operating state for the first and second efracking transformer, a speed of the first and second cooling fan, a temperature of the first and second efracking transformer, and a temperature of the first and second cooling fans to the new operating state for the first and second efracking transformer, a speed of the first and second cooling fan, a temperature of the first and second efracking transformer, and a temperature of the first and second cooling fans.

17.
