1. A hydraulic fracking system, comprising:
switchgears each configured to receive electric power at a first voltage level from a power generation system, and output electric power at the first voltage level;
a transformer configured to receive electric power at the first voltage level from the power generation system, and output electric power at a second voltage level that is less than the first voltage level; and
variable frequency drive (VFD) systems each configured to receive electric power at the first voltage level from one of the switchgears, receive electric power at the second voltage level from the transformer, use the received electric power at the second voltage level to receive a communication from a fracking control center, and use the received electric power at the first voltage level to respectively drive a motor mechanically coupled to a hydraulic pump based on the communication.
