摘要： A communication stack performance of an Intelligent Electronic Device (IED) is analyzed in a communication network of a Substation Automation (SA) system. The IED processes network messages that are transferred with, or belonging to, a specific configurable SA communication service. A plurality of application level scenarios corresponding to a high communication load is executed. Among all network messages captured or intercepted during the scenario, the network messages destined to the IED and sent by the IED in response are identified. A number of the identified messages, a number of specific communication protocol elements or data items related to a service-specific property, and a number of changed protocol elements, which are indicative of an SA event, for which the value of the data item has changed compared to the value of the same data item in a previous message, are determined. An IED-intrinsic processing time of the identified messages is likewise determined, based on which parameter values of a service specific processing time model are calculated.

摘要： Protection, measurement and control IEDs in a substation compute if switches they control may be operated safely, according to interlocking rules or physical principles as well as the dynamic topology of the substation. The IEDs have access to the substation electrical topology, to real-time information generated by other IEDs, and to the rules for interlocking. A standardized Substation Configuration Description (SCD) of the substation for which a Substation Automation system is intended, and a standardized description of the implemented device functions or capabilities of an individual IED are utilized. The substation topology is available from SCD file, real time information about the position of switches and line voltage/current can be obtained via an appropriate protocol, and the interlocking rules are available in script form. These features apply both to simulated and real devices, and increase system testing possibilities by supporting an efficient configuration of a simulation.

摘要： A method and system are provided for operation of substations in which protection, control and measurement devices (e.g., Intelligent Electronic Devices (IEDs)) exchange operational data over a data network, for example, according to IEC standard 61850. During maintenance, commissioning and fault situations, when one or several IEDs are inoperable, the data that these IEDs would have produced is substituted to ensure availability of the substation. To this effect, a dedicated substitute device is permanently installed that can take the role of any IED, and that is automatically configured out of a standard configuration description (SCD) file that describes the SA system.

摘要： An exemplary Substation Automation testing tool for IEC 61850 compliant substations is disclosed. The testing tool verifies the configuration of a first Intelligent Electronic Device (IED) that is part of a Substation Automation (SA) system and initially 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 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.

摘要： 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.

摘要： 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.
