Parameter monitoring and control for an electric driven hydraulic fracking system

A method for pumping a fracking media into a well, comprising:

• driving, by a variable frequency drive (VFD), an electric motor associated with the VFD to control the electric motor to drive a hydraulic pump in an operation of hydraulic fracturing;
• monitoring, by a controller, a pump speed parameter associated with the operation of hydraulic fracturing to determine whether the pump speed parameter deviates beyond a pump speed parameter threshold;
• and
• initiating, by the controller, a corrective action, in response to the pump speed parameter deviating beyond the pump speed parameter threshold, to maintain the operation of hydraulic fracturing.

An electric driven hydraulic fracking system for pumping a fracking media into a well, comprising:

• a variable frequency drive (VFD) for driving an electric motor at a VFD voltage level to control operation of the electric motor to drive a hydraulic pump;
• and
• a controller associated with the VFD and configured to
• determine whether a cable connecting a feeder of a power distribution system to a connection associated with the VFD is correctly plugged in based on a pulse train sent from the feeder, and
• generate an alert, in response to determining that the VFD is not correctly plugged in.
