Modular remote power generation and transmission for hydraulic fracturing system
CAFCFirst Claim
1. A hydraulic fracturing system for fracturing a subterranean formation comprising:
- an electric motor;
a pump coupled to the motor, and that has a discharge in fluid communication with a wellbore that intersects the formation, so that when the motor is activated and drives the pump, pressurized fluid from the pump pressurizes the wellbore to fracture the formation;
a variable frequency drive in communication with the electric motor, and that controls the speed of the motor, and performs electric motor diagnostics to prevent damage to the electric motor;
a source of electricity that is disposed a long distance from the electric motortransmission lines that connect the source of electricity to the electric motor and that span the long distance between the source of electricity and the electric motor; and
a switch gear between the transmission line and the source of electricity, and another switch gear between the transmission line and the electric motor.

Abstract
A hydraulic fracturing system for fracturing a subterranean formation includes a power generation system, a transmission section, and an equipment load section. The power generation system includes a turbine generator that generates electricity that is used to power equipment in the equipment load section. The equipment in the equipment load section conditions and pressurizes fluid that is injected into a wellbore for fracturing the formation. The power generation and equipment load sections are distal from one another are separated by a long distance. The transmission section connects the power generation and equipment load sections, and thus spans the long distance between these sections.

8. A method of fracturing a subterranean formation comprising:
-
driving a pump with an electric motor; transmitting electricity via a transmission line to the electric motor from a power source that is a long distance from the electric motor, wherein a first switchgear is positioned between the power source and the transmission line and a second switchgear is positioned between the transmission line and the electric motor; pressurizing a fluid with the pump to form a pressurized fluid; and fracturing the subterranean formation by directing the pressurized fluid to a wellbore that intersects the subterranean formation. - View Dependent Claims (9, 10, 11, 12, 13, 14)
