Abstract:
A pump system includes an interface detection meter (380) arranged at a pipeline assembly (350), a drive assembly (322, 324) for controlling speed of a pump (302, 304, 306, 308) arranged at the pipeline assembly (350), a discharge pressure control assembly and/or flow control assembly for controlling discharge pressure of the pump system, and a control assembly (382, 384, 386, 388, 390, 392, 396) operably coupled to the drive assembly (322, 324) and/or the discharge pressure control assembly and/or the flow control assembly. A logic control (382) of the control assembly (382, 384, 386, 388, 390, 392, 396) receives fluid data provided by the interface detection meter (380), and forwards the fluid data for calculating speed set points for the drive assembly (322, 324) and/or discharge pressure control parameter and/or set points for the discharge pressure control assembly, and/or flow rate control set points for the flow control assembly.
Abstract:
A method and controller for operating a pumping station. The method includes receiving (1102), by at least one controller (910, 952), sensor data (712) of a first pumping station (900) corresponding to a liquid being transported from the first pumping station (900). The method includes predicting (1104) arrival of the liquid, by the at least one controller (910, 952), at a second pumping station (900). The method includes executing (1106) one or more pump models (720), by the at least one controller (910, 952), according to the sensor data (712) to determine an optimal pumping configuration. The method includes operating (1108) one more pumps of the second pumping station (900), by the at least one controller (910, 952), according to the optimal pumping configuration.
Abstract:
A method and controller for creating a digital twin of a pump. The method includes receiving, by a controller, a specification curve corresponding to a centrifugal pump. The method includes building and executing, by the controller, a first model of the centrifugal pump, based on the specification curve. The method includes receiving sensor data corresponding to and during the operation of the pump. The method includes updating the first model according to the sensor data to produce an updated model and storing the updated model as a digital twin of the centrifugal pump.
Abstract:
The pump systems (pump + driver) used in a pump station are selected based on the type of fluid or batch. The selection is of the more efficient pump systems for that batch. Less efficient pumps are avoided. When a new batch is detected, the selection is performed again for that new batch, which may result in a different combinations of pump systems for a given pump station. If variable speed pump drives are available, the efficiency at the desired speed is used for selection. The cost of energy (utilities) by pump station may alternatively or additionally be used to select the speed or combination of pump systems. The pump station and pipeline operation is optimized for efficiency of pump systems and/or cost of energy (utilities) for the different pump systems based on pipeline inventory and local utilities tariffs.
