Variable frequency drive configuration for electric driven hydraulic fracking system

a hydraulic fracking and variable frequency drive technology, which is applied in the direction of positive displacement liquid engines, substations, borehole/well accessories, etc., can solve the problems of limiting the horsepower (hp) that the hydraulic pumps may operate, driving up the cost of fracking operation, and adding expense and possible delays

Abstract

An electric driven hydraulic fracking system is disclosed. A pump configuration that includes the single VFD, the single shaft electric motor, and the single hydraulic pump that is mounted on the single pump trailer. A pump configuration includes a single VFD configuration, the single shaft electric motor, and the single shaft hydraulic pump mounted on the single pump trailer. The single VFD configuration converts the electric power at the power generation voltage level distributed from the power distribution trailer to a VFD voltage level and drives the single shaft electric motor to control the operation of the single shaft electric motor and the single hydraulic pump. The VFD voltage level is a voltage level that is required to drive the single shaft electric motor. The VFD configuration also controls operation of the auxiliary systems based on the electric power at the auxiliary voltage level.

BACKGROUNDField of Disclosure

[0001] This application is a U.S. Nonprovisional application which claims the benefit of U.S. Provisional Application No. 62 / 805,521 filed on Feb. 14, 2019, which is incorporated herein by reference in its entirety. This application also incorporates U.S. Nonprovisional application Ser. No. 16 / 790,392 herein by reference in its entirety. This application also incorporates U.S. Nonprovisional application Ser. No. 16 / 790,538.Field of Disclosure

[0002] The present disclosure generally relates to electric driven hydraulic fracking systems and specifically to a single Variable Frequency Drive (VFD), a single shaft electric motor, and a single hydraulic pump positioned on a single pump trailer.Related Art

[0003] Conventional hydraulic fracking systems are diesel powered in that several different diesel engines apply the power to the hydraulic pumps as well as several types of auxiliary systems that assist the hydraulic pumps to execute the fracking, such as hydraul...
