Abstract
A hydraulic fracturing system includes a turbine generator for producing electricity at a well site, the turbine generator producing electrical energy at a voltage. The system also includes an electric pump electrically coupled to the turbine generator and receiving operative power from the turbine generator. The system further includes switch gear arranged between the electric pump and the turbine generator, the switch gear distributing electrical energy from the turbine generator to the electric pump, wherein the voltage remains substantially constant from the turbine generator to the electric pump.
Claims20
A hydraulic fracturing system, comprising:
- a plurality of turbine generators for producing electricity at a well site, the plurality of turbine generators producing electrical energy at a voltage;
- and
- a plurality of electric pumps, positioned on a support structure, electrically coupled to the plurality of turbine generators, each electric pump of the plurality of electric pumps being configured to operate at the voltage, wherein the voltage is distributed to the plurality of electric pumps without being conditioned by a transformer.
A hydraulic fracturing system, comprising:
- a plurality of turbine generators for producing electricity at a well site, the plurality of turbine generators producing electrical energy at a voltage;
- a plurality of electric pumps, positioned on a support structure, electrically coupled to the plurality of turbine generators, each electric pump of the plurality of electric pumps being configured to operate at the voltage after distribution via one or more cables wherein the voltage is not intentionally stepped up or down between the plurality of turbine generators and the plurality of electrics pumps;
- and
- a variable frequency drive (VFD), positioned on a second support structure, connected to at least one motor to control a speed of the at least one motor, the at least one motor driving an electric pump of the plurality of electric pumps, wherein the VFD also operates at the voltage.
