High horsepower pumping configuration for an electric hydraulic fracturing system

A hydraulic fracturing system for fracturing a subterranean formation, comprising:

• a first support structure, forming a pumping trailer, comprising:
• three electric pumps fluidly connected to a well associated with the subterranean formation and configured to pump fluid into a wellbore associated with the well at a high pressure so that the fluid passes from the wellbore into the subterranean formation and fractures the subterranean formation;
• at least one electric motor providing operational energy to the three electric pumps;
• a first support component, the first support component regulating operation of at least one of the three electric pumps;
• and
• a cable management system, associated with the first support structure, for coupling the three electric pumps to the at least one electric motor and the first support component;
• and
• a second support structure, forming a support trailer, comprising:
• a second support component, the second support component regulating electric power transmission to at least one of the three electric pumps;
• and
• a control system for monitoring or controlling one or more operational parameters of the three electric pumps, the second support structure having integrated instrumentation and cabling for coupling the second support component and the control system.

A hydraulic fracturing system for fracturing a subterranean formation, comprising:

• at least one generator;
• at least one switch gear receiving electrical power from the generator;
• three electric pumps, arranged on a first support structure, the three electric pumps coupled to a well associated with the subterranean formation and powered by at least one electric motor arranged on the first support structure, the three electric pumps configured to pump fluid into a wellbore associated with the well at a high pressure so that the fluid passes from the wellbore into the subterranean formation and fractures the subterranean formation;
• a transformer, arranged on a second support structure, positioned between the switch gear and at least one electric motor, the transformer reducing a voltage output from the at least one switchgear;
• and
• a control system, arranged on the second support structure, for monitoring or controlling one or more operational parameters of the three electric pumps, the second support structure having integrated instrumentation and cabling for coupling the transformer and the control system.
