The at least one pump of the hydraulic power unit is in direct fluidic communication with the pressure control equipment.
Claims15
A system comprising:
- a pressure control equipment;
- a hydraulic power unit comprising:
- a fluid reservoir;
- and
- at least one pump comprising an electric motor configured to power the pump;
- a programmable logic controller (PLC) in electric communication with the hydraulic power unit;
- and
- a power management system connected to the PLC, wherein the power management system comprises:
- a capacitor management system connected to a supercapacitor;
- and
- a stored electrical energy system,
- wherein the at least one pump of the hydraulic power unit is in direct fluidic communication with the pressure control equipment,
- wherein the PLC is configured to evaluate a power need of the hydraulic power unit,
- wherein the PLC is configured to send instructions to discharge the supercapacitor if the power need of the hydraulic power unit aligns with a first operational status of the hydraulic power unit,
- wherein the PLC is configured to send instructions to use the stored electrical energy system if the power need of the hydraulic power unit aligns with a second operational status of the hydraulic power unit, and
- wherein the first operational status requires a higher power demand than the second operational status.
