  • auto mapping and Configuration method of iec 61850 information model based on opc ua
    Energies, 2016
    Co-Authors: Injae Shin, Byung Kwen Song, Doo-seop Eom
    Abstract:

    The open-platform communication (OPC) unified architecture (UA) (IEC62541) is introduced as a key technology for realizing a variety of smart grid (SG) use cases enabling relevant automation and control tasks. The OPC UA can expand interoperability between power systems. The top-level SG management platform needs independent middleware to transparently manage the power information technology (IT) systems, including the IEC 61850. To expand interoperability between the power system for a large number of stakeholders and various standards, this paper focuses on the IEC 61850 for the digital substation. In this paper, we propose the interconnection method to integrate communication with OPC UA and convert OPC UA AddressSpace using system Configuration Description language (SCL) of IEC 61850. We implemented the mapping process for the verification of the interconnection method. The interconnection method in this paper can expand interoperability between power systems for OPC UA integration for various data structures in the smart grid.

  • load restoration in a high or medium voltage substation
    2015
    Co-Authors: Wolfgang Wimmer
    Abstract:

    The present invention is concerned with simplified Configuration as well as supervision and testing of load restoration functions in high or medium voltage substations of electrical power transmission or distribution networks. The invention takes advantage of the fact that all information for load restoration is available from a standardized Configuration representation and from dynamically observable events. Specifically, the IEC 61850 Substation Configuration Description (SCD) file includes the substation single line, the bus bar or breaker failure protection functionality related to it, and the way how reclosing commands can be conveyed for the restoration process. A load restore function or load transfer application observes the execution of a protection trip function and the concurrent connection state of the bays (6.5, 6.6, 6.7) to bus bars (1.1, 1.2) in order to automatically restore the power flow across a failed bus bar segment (1.1) to a parallel healthy bus bar segment (1.2).

  • Configuration of an iec 61850 teleprotection ied for inter substation communication
    2013
    Co-Authors: A Gygax, Wolfgang Wimmer
    Abstract:

    The present invention is concerned with a teleprotection system engineering process that starts with the generation of a Description of two teleprotection Intelligent Electronic Devices (IEDs) (15,25) at two substations (10,20) connected via a teleprotection link (300), based on the intended functionality or semantics to be transferred between the substations and the needed telecommunication properties for this semantics. A corresponding teleprotection link definition (301) is used as a unique input for a co-generation of two IED Capability Description (ICD) files (TP_IED_A.ICD;TP_IED_B.ICD) representing the two teleprotection IEDs or IEC 61850 gateways. A single ICD generation module or function block (160) performs this task thus reducing the possibilities for erroneous manual input of the link definition data. The generation of the two ICD files occurs prior to, and hence independently of, any generation of Substation Configuration Description (SCD) files, i.e. before a detailed Substation Automation (SA) system engineering actually takes place.

  • iec 61850 scl more than interoperable data exchange between engineering tools
    2005
    Co-Authors: Wolfgang Wimmer
    Abstract:

    The IEC 61850 SCL language for Substation Configuration Description is standardized for the interop- erable exchange of engineering data between engineering tools. Its model based approach allows to use it also for other purposes. As an illustration this paper explores some examples, like usage for storage of protection parameters, maintenance support, control center gateway engineering, and application Configuration wizards.
