  • a louver controller 5 is also in communication with the main control system 4, to open and close louvers (for e.g. ventilation and fire control).
  • the main control system 4 receives data from a hydraulic pump controller 6 (e.g. a PLC) and provides a power command Ac to the hydraulic pump controller 6.
  • the hydraulic pump controller 6 in turn provides the required displacement command Dc to the hydraulic pump 9c based on pump pressure feedback Pp (from the pressure sensor 13c).
  • the main control system 4 also provides data regarding requested cylinder speed RCS to the valve controller 7, which in turn determines and provides the valve flow control signal Vf to the control valves 36c, 37c, as described above.

  • the hydraulic fracturing pressure generated in the well is a result of the well pressure and the hydraulic pressure generated by the plungers.
  • the well pressure (which is sensed by the sensor 16) is communicated to the valve controller PLC 7, which controls the control valves 36a-c, 37a-c and also determines the estimated power consumption EPC, which is transmitted to the main control system 4.
  • the prime mover fuel supply e.g.
  • the turbine fuel injection may thus be governed by the well pressure, or rather the variations in pressure, as sensed continuously by the sensor 16.
  • the blazing turbine fuel control receives pressure reading from the hydraulic control system, based on the pressure and rate reading from the hydraulic fracturing pressure.
  • the hydraulic control system then performs a control action based on a set-point (rate/pressure) identified and set by the operator.
  • the “delay” which is inherent in the hydraulic components, or as controlled by the main control system 4, provides sufficient time for the turbine fuel control to "predict” what is going to happen, and take action before it happens.
  • the prime mover can - before the requirement arises - either increase the fuel injection (open throttle) to be ready for the higher demand from the hydraulic pumps, or lower the fuel injection (restrict throttle) to adapt to the estimated future requirement of torque, and thereby accommodate the change in rate/pressure.
  • This function is particularly useful in embodiments where the prime mover is a gas turbine engine, as such turbines normally operate at high rotational speeds, and have low torque.
  • the control system may in this fashion prevent the gas turbine engine from over-speeding, and further give the gas turbine engine a head-start on a predicted increased torque demand.
  • valve controller 7 and pressure sensor 16 are sensing this, based on sensed pressure variations.
  • the set point may also be defined based on a prioritized list, defined by an overall control system, of how deviating conditions are to be handled. Based on rate/pressure difference between the set point and the actual pressure reading (as sensed by 16), there will occur a situation that the actual power command Ac (fed to main controller 4 by the pump controller 6) differs from (less or more) the estimated power consumption EPC (fed to the main controller 4 by the valve controller 7).
