Patent number: 9816509Abstract: A device and a method for operating multiple centrifugal pumps are disclosed. The device can include a communication interface for receiving as at least one input information, an instantaneous pressure drop and an instantaneous flow rate per pump or speed of the centrifugal pumps, and for transmitting output information to the centrifugal pumps, where the output information reflects a reference value for the number of centrifugal pumps to be operated in parallel. The device can contain a data storage unit and a processing unit, which determine from input information and additional information an instantaneous efficiency, a first expected efficiency under the assumption that the actual number is reduced by one, and a second expected efficiency under the assumption that the actual number is increased by one, and which can generate the reference value depending on which of the instantaneous or first expected or second expected efficiencies has a highest value.Type: GrantFiled: January 29, 2015Date of Patent: November 14, 2017Assignee: ABB Schweiz AGInventors: Marcel Blaumann, Rüdiger Franke, Olaf Reismann

Patent number: 7311264Abstract: The novel method and device provide for process control—closed-loop control or open-loop control—for a thermal system with an obstruction-curved and/or thick-walled component through which a medium flows. The wall temperatures of the component are detected, the heat flux density of the heat flux from the medium into the wall of the component is determined, the respective heat transmission coefficient is determined, using the wall temperatures. The heat flux density, and the heat transmission coefficient thus determined are used to influence the medium properties, with the heat stresses in the component being taken into account.Type: GrantFiled: March 15, 2004Date of Patent: December 25, 2007Assignee: ABB Research LtdInventors: Rüdiger Franke, Klaus Krüger, Manfred Rode

Patent number: 6917838Abstract: An open-loop and closed-loop control method is described for starting up or shutting down a process component of a technical process. At least one manipulated variable that is fed to the process is formed by a control device and an upstream model-assisted pilot control. The pilot control contains an optimizer and a process model. The optimizer is fed at least one command variable for the technical process. At least one optimized model manipulated variable which the optimizer outputs is fed to a process model of the pilot control and, is added to at least one output variable of the control device to form the manipulated variable. A model output variable of the process model is fed to the control device as a set-point and fed back to the optimizer along with variables which cannot be measured in the technical process. A device for implementing the method is also described.Type: GrantFiled: June 17, 2002Date of Patent: July 12, 2005Assignee: ABB Research Ltd.Inventors: Klaus Krüger, Manfred Rode, Rüdiger Franke

Patent number: 6556914Abstract: A semiautomatic control system or control method ensures a driving method which is as energy-saving as possible. In the system, there is both a) manual inputting of control data, for example a definition of a vehicle speed specified value, by the driver of the vehicle and b) automatic determination of the most energy-saving vehicle speed as a function of predefined peripheral conditions, for example a general travel schedule, the topology of a route, vehicle-specific peripheral conditions and the like. An inference system determines which of these two values is smaller, and the smaller value is used to make possible safe and at the same time energy-saving travel (or journey). A safety check of the manual travel speed input value and of the automatically determined travel speed specified value can also be performed to reliably prevent a maximum permissible travel speed value from being exceeded.Type: GrantFiled: April 12, 2001Date of Patent: April 29, 2003Assignee: DaimlerChrysler Rail Systems GmbHInventors: Ueli Nievergelt, Rüdiger Franke
