A load phase back system for controlling a plurality of electrical loads in an electric fracturing spread. The load phase back system comprises monitoring circuitry configured to monitor input power received from an electric power source. The monitoring circuitry determines a measured voltage and a measured frequency of the input power. A controller controls the power applied to the plurality of electrical loads from a power bus according to a value of the measured voltage and a value of the measured frequency of the input power. The controller reduces power applied to selected ones of the plurality of electrical loads from the power bus when at least one of the measured voltage is less than a first threshold and the measured frequency is less than a second threshold.

System and method for controlling hybrid and grid power in an electric fracturing spread

A blender power unit (BPU) for use in fracturing jobs. The BPU comprises a transformer having an input and an output and configured to receive electrical power via the input at a first voltage to output electrical power via the output at a second voltage; a motor power bus coupled to the output of the transformer; a motor starter bus; at least one motor soft starter having an input coupled to the motor power bus and having an coupled to the motor starter bus; a plurality of electric power relays coupled to the motor power bus and configured to supply electric power from the motor power bus to a load when in a closed state; and a plurality of start electric power relays coupled to the motor starter bus and configured to supply electric power from the motor starter bus to a load when in a closed state.

Blender power unit for electric fracturing spread

An apparatus for managing a plurality of electric power generators is configured to receive measurements of a plurality of parameters related to performance of one or more of a plurality of generators and detect, based on the measurements, that values of at least two of the plurality of parameters measured for a first generator of the one or more generators do not match respective predetermined values of the at least two parameters for the first generator. In response to the detecting, the apparatus determines that the first generator is faulty and generates a signal to perform at least one of shutting down the first generator or disconnecting the first generator from at least one second generator of the plurality of generators, in response to determining that the first generator is faulty.
