20080234872 | Validating a standardized configuration description - The present disclosure is concerned with a validation of a configuration description of automated devices in a power network such as a Substation Automation (SA) system, or of a part or component thereof such as an individual Intelligent Electronic Device (IED), that is extended beyond the mere XML schema validation as provided by the known SCL-validation tools. In particular, the disclosure introduces machine-based validation of notations, requirements and/or conventions to be respected by the configuration description and/or the SA system, but not incorporated in or represented by the standardized syntax of the XML schema as defined in part 6 of the IEC 61850 standard. To this end, notations, requirements and/or conventions are initially converted into, or defined as, extended or augmented rules encoded in computer readable format. The content or information of a file having an Substation Configuration description Language (SCL) compliant description of an SA system, or of a part or component there of, is then read by parsing the file and checked for conformance to the rules. Any inconsistency, error, wrong configuration or insufficient description found is displayed to a user, who may then correct the content or information in the file. The procedure according to the disclosure can contribute, in an automated manner, to the correctness of the description of a Substation Automation (SA) system beyond the pure syntactical adherence to the IEC 61850 standard. | 09-25-2008 |
20090070051 | INTELLIGENT ELECTRONIC DEVICE CONFIGURATION VERIFICATION - A Substation Automation testing tool for IEC 61850 compliant substations is disclosed. It is concerned with the verification of the configuration of a first Intelligent Electronic Device (IED) that is part of a Substation Automation (SA) system and that has initially been configured to perform measurement, protection and/or control functions in accordance with a substation configuration specification. Configuration information is first read from an internal server of the first IED and transformed according to a dedicated data model. Related information is then read from e.g. a second IED that has initially been configured to perform the same functions as the first IED, or from a Substation Configuration Description (SCD) file, and likewise transformed. The transformed data is then compared in order to identify discrepancies or inconsistencies and to resolve errors introduced by the IED configuration process. | 03-12-2009 |
20090070062 | SYSTEM LEVEL TESTING FOR SUBSTATION AUTOMATION SYSTEMS - The disclosure is concerned with the testing of system level functionality involving several Protection, Control and Measurement (PCM) Intelligent Electronic Devices (IEDs) of a Substation Automation (SA) system for IEC 61850 compliant substations. An extensive testing of all conceivable control or protection functions/applications of an extended SA system comprising a large number of IEDs with a multitude of configurations is facilitated by simulating at least one of the IEDs in a testing device. Hence, only a limited number of IEDs are physically present as individual devices in a test environment, the behaviour of at least one further IED being simulated by a dedicated testing device with appropriate data processing means. The testing device sends network messages indicative of the behaviour of the simulated IED according to its communication and device configuration over a substation communication network to the physically present IED to be tested. The proper working of the configured IED functions, i.e. the expected correct action as triggered by the testing device, are then verified. | 03-12-2009 |
20090076762 | INTELLIGENT ELECTRONIC DEVICE CONFIGURATION INSPECTION - The present disclosure is concerned with a Substation Automation testing tool which combines the information found in the SCL (Substation Configuration Language) File of a substation (Substation Configuration Description) or an IED (IED Capability description) with substation-relevant data extracted from the Substation Communication network traffic. By means of a standard laptop computer as a message interceptor connected to a substation communication network, IEC 61850 relevant data is retrieved and analysed. Hence, the disclosure allows for consistency verification without revision handling and achieves a reduction of the time and efforts for commissioning or testing a substation installation. | 03-19-2009 |
20090210453 | Service for verifying consistency of replicated data - Any external application using data access functionality can use the attribute consistency service to update and synchronize attribute value for an entity. The application can access the relations of an entity, which are stored in an entity reference database. In case of inconsistent attribute values, a master attribute value is determined which is then written to the defined attributes of the applications. | 08-20-2009 |
20110137878 | Data Consistency Validation - An entity to be validated for consistency is loaded into the buffer of the consistency service, a signal to verify the existence of a specific data set of an IT system is then sent by the consistency service to the IT system holding the entity to be validated for consistency, and the consistency validating information is stored in the output means, said consistency validating information depending on the signal being sent back to the consistency service. | 06-09-2011 |
20110160923 | METHOD AND APPARATUS FOR MONITORING THE PERFORMANCE OF A POWER DELIVERY CONTROL SYSTEM - A power delivery control system and a method of monitoring the same are provided. The control system includes a plurality of computers. Initial data is collected based on the processes running on each computer. If the initial data meets threshold criteria, more detailed data is collected to facilitate root cause analysis. All data is collected using operating system kernel interfaces and is time stamped. On each computer, correlated collected data may be displayed in a GUI. | 06-30-2011 |
20120116542 | PROCESS CONTROL OVERVIEW ON A SUPERVISORY CONTROL SYSTEM DISPLAY UNIT - A method for enabling supervision of a technical system and a supervisory control system for supervising a technical system are provided. An overview picture of the technical system is shown on a display unit and the overview system receives input signals indicating a selection of at least one object of interest shown in the overview picture. In response to these input signals, a detailed information view is displayed at least partly overlapping the overview picture, where the detailed information view is associated with the object and includes detailed information of the object. | 05-10-2012 |
20130080959 | SIMPLIFIED NAVIGATION AMONG PROCESS CONTROL VIEWS IN A PROCESS CONTROL SYSTEM - A method is provided for simplifying navigation for a user among process control views on a user terminal display of a process control system. The method includes presenting a current main process control view in a first main view window together with a number of additional views in a second additional views window, receiving, from the user, a selection of a view in the second window to be main process control view, setting the selected view as current main process control view, choosing a group of views to be presented as additional views in the second window based on an additional view selection criterion, and repeating presenting current main process control view according to the received selection with the chosen group of views as additional views in the second window. Also provided are a user terminal and a non-transitory computer-readable recording medium having a computer program for simplifying such navigation. | 03-28-2013 |
