A hydraulic fracturing system for fracturing a subterranean formation, comprising:
- a primary switchgear, arranged on a support structure, the primary switchgear electrically coupled to a power source to receive electrical power from the power source;
- a secondary switchgear, arranged on the support structure, the secondary switchgear positioned separately from the primary switchgear and within an enclosure, the secondary switchgear receiving an electrical input from the primary switchgear and including a plurality of feed connections for supplying the electrical power to a plurality of fracturing equipment;
- and
- support equipment, arranged on the support structure, the support equipment providing one or more services to at least the secondary switchgear,
- wherein at least one of the primary switchgear or the secondary switchgear is a single-bus power distribution system, the single-bus power distribution system comprising:
- a single common high amperage bus receiving energy from one or more generators of the power source at one or more main breakers, the single common high amperage bus distributing the electrical power to a feeder circuit, the single common high amperage bus is rated for at least 2000A.
An electrical distribution system for providing electrical to hydraulic fracturing equipment, comprising:
- a primary bus, arranged on a support structure, electrically coupled to at least one generator, the at least one generator providing electrical power to a breaker coupled to the primary bus, the breaker also arranged on the support structure;
- and
- a secondary bus, arranged on the support structure, electrically coupled to the primary bus via at least one cable,
- the secondary bus being positioned within an enclosure and including a plurality of feed connections for supplying the electrical power to at least one piece of the hydraulic fracturing equipment,
- wherein the secondary bus comprises a single-bus power distribution system having a single common high amperage bus receiving the electrical power from the at least one generator at one or more main breakers and distributing the electrical power to a feeder circuit, the single common high amperage bus is rated for at least 2000A.
