Abstract

A system for powering electric hydraulic fracturing equipment, the system including a power storage system and electric powered hydraulic fracturing equipment in selective electrical communication with the power storage system. The system further includes at least one circuit breaker between the power storage system and the electric powered hydraulic fracturing equipment, the circuit breaker configured to facilitate or prevent electrical communication between the power storage system and the electric powered hydraulic fracturing equipment.

First claim

The invention claimed is:

1. A hydraulic fracturing power system, comprising:
a power source;
a power storage system;
an electric powered hydraulic fracturing pump in selective electrical communication with the power storage system; and

a circuit breaker between the power storage system and the electric powered hydraulic fracturing pump, the circuit breaker having an open position that opens an electric circuit between the electric powered hydraulic fracturing pump and the power storage system, and a closed position that closes the electric circuit, the circuit breaker varying between the open position and the closed position as required to power the electric powered hydraulic fracturing pump while the electric powered hydraulic fracturing pumps are in place at a wellsite, wherein the circuit breaker comprises a first circuit breaker, and the hydraulic fracturing power system further comprising:
a power source in selective electric al communication with the electric powered hydraulic fracturing pump, and
a second circuit breaker, wherein the second circuit breaker is electrically connected to the power source, and wherein the first circuit breaker is electrically connected to the power storage system.

2. The system of claim 1 , wherein the power storage system is at least one solid state battery selected from the group consisting of electrochemical capacitors, lithium ion batteries, nickel-cadmium batteries, and sodium sulfur batteries.

3. The system of claim 2 , wherein the power storage system is at least one flow battery selected from the group consisting of redox batteries, iron-chromium batteries, vanadium redox batteries, and zinc-bromine batteries.

4. The system of claim 3 , wherein the at least one solid state battery or the at least one flow battery is rechargeable.

5. The system of claim 1 , wherein each of the first circuit breaker and the second circuit breaker is electrically connected to the electric powered hydraulic fracturing pump via a common bus.

6. The system of claim 1 , wherein the circuit breaker comprises a first circuit breaker, and further comprising:
a power source in selective electrical communication with the electric powered hydraulic fracturing pump, wherein both the power source and the power storage system are electrically connected to the first circuit breaker.

7. The system of claim 1 , wherein the power storage system is electrically connected to the circuit breaker via a power line.

8. The system of claim 1 , wherein the power storage system is mounted to a trailer.

9. The system of claim 1 , wherein the circuit breaker is substantially enclosed in a switchgear housing.

10. A system for powering an electric hydraulic fracturing pump, comprising:
a power storage system having;
an electric powered hydraulic fracturing pump in selective electrical communication with the power storage system; and

a circuit breaker between the power storage system and the electric powered hydraulic fracturing pump, the circuit breaker configured to facilitate or prevent electrical communication between the power storage system and the electric powered hydraulic fracturing pump while the electric powered hydraulic fracturing pumps are in place at a wellsite, wherein the circuit breaker comprises a first circuit breaker, and further comprising:
a power source, and
a second circuit breaker, wherein the second circuit breaker is electrically connected to the power source, and the second circuit breaker is electrically connected to the power storage system.

11. The system of claim 10 , further comprising:
a power source, wherein both the power source and the power storage system are electrically connected to the circuit breaker, and the circuit breaker facilitates or prevents communication between the power storage system, the power source, and the electric powered hydraulic fracturing pump as required to power the electric powered hydraulic fracturing pump and maintain a charge in the power storage system.

12. The system of claim 11 , wherein at least one of the power source and the power storage system are electrically connected to the first circuit breaker or the second circuit breaker via a power line.

13. The system of claim 10 , wherein the circuit breaker is substantially enclosed in a switchgear housing.

14. The system of claim 13 , further comprising:
software in communication with the power storage system, the software configured to monitor a state of the power storage system and to integrate control of the power storage system with other features of the system for powering electric hydraulic fracturing equipment.

15. The system of claim 10 , wherein the power storage system is rechargeable.

16. The system of claim 10 , wherein the power source is electrically connected to the first circuit breaker via a power line, and wherein the power storage system is located adjacent a switchgear housing and electrically coupled directly to the switchgear housing without a power line.

17. A system for powering an electric hydraulic fracturing pump, comprising:
a power storage system having:
an electric powered hydraulic fracturing pump in selective electrical communication with the power storage system; and
a circuit breaker between the power storage system and the electric powered hydraulic fracturing pump, the circuit breaker configured to facilitate or prevent electrical communication between the power storage system and the electric powered hydraulic fracturing pump while the electric powered hydraulic fracturing pumps are in place at a wellsite, wherein the power storage system is at least one solid state battery selected from the group consisting of electrochemical capacitors, lithium ion batteries, nickel-cadmium batteries, and sodium sulfur batteries.

18. The system of claim 17 , wherein the power storage system is at least one flow battery selected from the group consisting of redox batteries, iron-chromium batteries, vanadium redox batteries, and zinc-bromine batteries.
