SYSTEM FOR HYDRAULIC FRACTURING INCLUDING MOBILE POWER-GENERATING SUBSYSTEM WITH DIRECT-COUPLED GENERATOR

摘要

System for hydraulic fracturing is provided. A generator (22) directly coupled to a gas turbine engine (24) without a rotational speed reduction device. Thus, generator (22) may operate at relatively high-speeds and may involve state-of-the art electromotive technologies, such as may include switched reluctance generators (SRG), synchronous reluctance generators (SynRG) or permanent magnet generators (PMG). Power circuitry (30) may be arranged to receive electric power generated by generator (22) and may be electrically connectable to a power bus (32). Gas turbine engine 24), generator (22) and power electronics circuitry (30) may each be respectively mounted onto a power generation mobile platform (34), and in combination constitute a mobile power-generating subsystem (20) that may be operationally arranged in combination with one or more hydraulic fracturing subsystems (50), mobile or otherwise, that can similarly take advantage of such electromotive technologies for motoring purposes.
