Abstract: An engine controller to control a plurality of engines is disclosed. The engine controller may determine that power to a load is to be increased, wherein the load is configured to be powered by one or more of the plurality of engines; determine that an engine, of the plurality of engines, is configured to provide supplemental power to the load after a temperature of the engine satisfies a threshold, wherein the threshold corresponds to a warm-up operation of the engine being completed; determine that the temperature of the engine does not satisfy the threshold; obtain, via an operator interface, an authorization to bypass the warm-up operation of the engine; and bypass, based on obtaining the authorization, the warm-up operation for the engine to permit the engine to provide instantaneous power to the load.

Abstract: A hybrid energy system including a controller that is coupled to at least one generator set and to at least one energy storage device. The controller is configured to cause the at least one generator set to operate at a first operational speed and a second operational speed in response to a change in the load. The controller receives notice that the at least one energy storage device is providing energy to the load and, in response thereto, to changes the amount of energy that the at least one generator set is providing to the load by causing the at least one generator set to operate at a third operational speed.

Abstract: A monitoring system for a fluid pump having a fluid end and a power end is provided. The monitoring system includes an inlet pressure sensor attached to an inlet manifold of the fluid end. The inlet pressure sensor generates a signal indicative of an inlet pressure of a fluid being supplied to the fluid end. The monitoring system includes a discharge pressure sensor attached to the fluid end. The discharge pressure sensor generates a signal indicative of a discharge pressure of the fluid exiting the fluid end. The monitoring system includes at least one accelerometer attached to the fluid end. The accelerometer generates a signal indicative of vibrational data of the fluid pump. The monitoring system includes a controller which receives signals from the inlet pressure sensor, the discharge pressure sensor and the accelerometer and determines a possible failure mode of the fluid pump.

Abstract: A pump monitoring and notification system for a hydraulic pump includes a transmission speed sensor and a controller. The transmission speed sensor is associated with a transmission connected to the pump to determine an output speed of the transmission. The controller is configured to access a transmission threshold, access a time threshold, and determine a rotational speed of the transmission based upon the transmission speed sensor. The controller is further configured to determine a variation in rotational speed of the transmission based upon the rotational speed, compare the variation in rotational speed of the transmission to the transmission threshold, and generate an alert signal when the variation in rotational speed of the transmission exceeds the transmission threshold for a time period exceeding the time threshold.

Abstract: A work cycle determination system for a fracking pump is provided. The work cycle determination system includes a pressure sensor adapted to generate a signal indicative of a pressure generated by the fracking pump, and a controller communicably coupled to the pressure sensor. The controller receives the signal indicative of the pressure generated by the fracking pump over a predefined period of time. The controller identifies a boundary of a work cycle within the predefined period of time by analyzing the signal. The controller also determines a peak pressure of the work cycle and a time duration of the work cycle. The controller further determines a type of the work cycle of the fracking pump based on the peak pressure and the time duration of the work cycle.
