Patent number: 11056877Abstract: A system and method for feeder protection in an electrical power network nodal point including at least three feeders. In the system and the method it is executed in an intelligent electronic device reserved for the feeder, on the basis of the at least one measured electrical quantity actual in the respective feeder, at least one first protection function monitoring a power system related condition of the respective feeder, as well as in a central intelligent electronic device, for at least one feeder, at least one second protection function monitoring the same power system related condition of the feeder. Furthermore the central intelligent electronic device is configured to further execute for the at least one feeder, on the basis of the at least one measured electrical quantity actual in the other feeders connected to the same nodal point, at least one third protection function monitoring the same power system related condition of the feeder.Type: GrantFiled: September 24, 2018Date of Patent: July 6, 2021Assignee: ABB Schweiz AGInventors: Jani Valtari, Ganesh Kulathu, Sixten Holm, Jakub Sipowicz

Patent number: 9496754Abstract: A method and a system for power management for a plant electrical network are provided. The power management system over a plant-wide communication network includes both concepts of hierarchical level and distributed level power management using multiple controllers. At least one controller in the power management system is configured for power management in a first local process area within the plant electrical network and is capable to communicate with at least a second controller configured for power management in a second local process area within the plant electrical network over the communication network.Type: GrantFiled: March 7, 2012Date of Patent: November 15, 2016Assignee: ABB Schweiz AGInventors: Ganesh Kulathu, Arinjai Gupta, Diogenis Papaevangelou, Willem Otto Van Der Wal, Wolfgang Wimmer, Martin Nykvist

Patent number: 9450407Abstract: Power management systems and methods are disclosed for a plant electrical network using plurality of controllers configured for power management such that a first controller from the plurality of controllers is configured to perform power management in a first local process area within the plant electrical network and can communicate with a second controller that is configured for power management in a second local process area within the plant electrical network, over a plant wide communication network. The power management function in the first local process area can be performed based on the information communicated between the first controller and the second controller and/or based on a power balance computation carried out for the plant wide electrical network or for the first local process area. The power management function can include slow load shedding.Type: GrantFiled: July 5, 2012Date of Patent: September 20, 2016Assignee: ABB Schweiz AGInventors: Ganesh Kulathu, Arinjai Gupta, Emilian-Ioan Anton

Patent number: 8942970Abstract: A method is disclosed for configuring an intelligent electronic device (IED) that includes enabling dynamic capability of the IED by a flexible data modeling technique to dynamically adapt a data model based on an application requirement using a configuration tool. A substation automation system is also disclosed which includes a local system equipment having a plurality of IEDs associated with the local system equipment and an IED configuration tool configured to interact with the firmware of each IED to configure the IED based on application requirements. The application configuration tool can include dynamic capability information of the IED to enable a flexible data model in the IED.Type: GrantFiled: December 9, 2009Date of Patent: January 27, 2015Assignee: ABB Research Ltd.Inventors: Sasi Kumar, Vivek Gopalakrishnan, Tobias Gentzell, Ganesh Kulathu

Patent number: 8923993Abstract: A method for engineering and configuration of one or more IEDs for a function in a substation automation system is disclosed. Also disclosed is a configuration wizard for implementing the method. The method includes creating pre-defined type definitions for an application function, providing a selectable menu for selection of appropriate parameters with respect to the application. Using these parameters and the pre-defined type definitions. The method includes creating process configuration outputs for the application function, and configuring the one or more IEDs based on the process configuration outputs.Type: GrantFiled: February 14, 2012Date of Patent: December 30, 2014Assignee: ABB Technology Ltd.Inventors: Ganesh Kulathu, Wolfgang Wimmer

Patent number: 8880658Abstract: A method, a substation automation apparatus and an intelligent electronic device (IED) are disclosed which are, for example, not limited only to publishing data (data emanating) from the IED. An exemplary method includes assigning a unique identifier to one or more data fields, where the one or more data fields is associated with a short address attribute in the data emanating from the intelligent electronic device; and dynamically updating the identifier based on user specific configuration data by an IED application configuration tool. The IED can include a list of functions; (e.g., each function being represented as a logical node; and each logical node containing data objects); and a flexible addressing scheme for configuring the data objects and publishing data from the IED, but not only data emanating from IED.Type: GrantFiled: December 2, 2011Date of Patent: November 4, 2014Assignee: ABB Technology LtdInventors: Ganesh Kulathu, Uwe Klich, Sasi Kumar, Vivek Gopalakrishnan, Tobias Gentzell, Padmasri Krishnamurthy

Patent number: 8788108Abstract: A method and system for distributed power management with individual IEDs in a substation are disclosed. An exemplary technique can include providing multiple IEDs in a power network in the substation and integrating an intrinsic load shedding function in each IED. The technique can include identifying a power imbalance state at an individual IED and load shedding the individual IED using an intrinsic load shedding function when a power imbalance state is identified in a coordinated manner to achieve distributed power management in the substation.Type: GrantFiled: February 14, 2012Date of Patent: July 22, 2014Assignee: ABB Technology LtdInventors: Ganesh Kulathu, Martin Nykvist, Wolfgang Wimmer, Otto Van Der Wal
