Electric powered hydraulic fracturing pump system with single electric powered multi-plunger fracturing pump
A hydraulic fracturing system includes a support structure having a first area at a first height and a second area at a second height, the first and second areas adjacent one another. The system also includes an electric powered, multi-plunger pump with an odd number of plungers, arranged in the first area, the electric powered pump coupled to a well, via outlet piping, and powered by at least one electric motor, also arranged in the first area. The system further includes a variable frequency drive (VFD), arranged in the second area, connected to the at least one electric motor, the VFD configured to control at least a speed of the at least one electric motor. The system also includes a transformer, arranged in the second area, the transformer positioned within an enclosure with the VFD, the transformer distributing power to the electric pump.
