Abstract
The IEC 61850 standard stipulates the Substation Configuration Description Language (SCL) file as a means to define the substation equipment, IED function and also the communication mechanism for the substation area network. The SCL is an eXtensible Markup Language (XML) based file which helps to describe the configuration of the substation Intelligent Electronic Devices (IED) including their associated functions. The SCL file is also configured to contain all IED capabilities including data model which is structured into objects for easy descriptive modeling. The effective functioning of this SCL file relies on appropriate validation techniques which check the data model for errors due to non-conformity to the IEC 61850 standard. In this research, we extend the conventional SCL validation algorithm to develop a more advanced validator which can validate the standard data model using the Unified Modeling Language (UML). By using the Rule-based SCL validation tool, we implement validation test cases for a more comprehensive understanding of the various validation functionalities. It can be observed from the algorithm and the various implemented test cases that the proposed validation tool can improve SCL information validation and also help automation engineers to comprehend the IEC 61850 substation system architecture.
Highlights
We propose a technique for verifying standard data compliance for arbitrary IEC 61850 based devices using Unified Modeling Language (UML) and XML Metadata Interchange (XMI)
In order to integrate multiple heterogeneous devices in a single communication network in a smart grid-based power grid system, the use of the standard data model in the system becomes very important. It is not easy for existing system engineers to correctly use the vast data model required in the new digital environment
The IEC 61850 standard data model continues to grow as the number of data standard models continues to expand from the substation to other domain, such as including IEC 61400-25 and IEC 61850-7-410
Summary
Various devices and operating systems from power plants to consumers have been introduced and utilized depending on the characteristics of such equipment. “Stand Alone” devices based on traditional standards are highly dependent on the technology of the manufacturer. Since the advent of Smart Grid technology, we have created a common standard through international standardization rather than the manufacturer-dependent technology, leading to the establishment of a system-oriented technology environment. The IEC 61850 international standard proposes communication network and data standardization for the automation of power system [2] [3] [4] [5]. In IEC 61850 Edition 1.0, standardization was limited to the substations domain while IEC 61850 Edition 2.0 extends the automation to all areas of power system [6]
