User Manual for IED Modeler

User Manual for IED Modeler

The IED Modeler/Designer is a comprehensive IED oriented SCL modelling tool for IEC 61850/61400 and companion standards. It has been designed to keep pace with the evolution of standards. Model Designer has been designed to address the diverse requirements of different types of users. It can be used by IEC 61850 Standard developers, IED vendors, stack vendors, researchers, engineers, utilities companies and people who are interested in applying Model Driven Architecture in system design. Feedback from this broad user base is allowing the product to evolve and we are continually adding new features to simplify the introduction of IEC 61850/61400 into production environments.

  • Part One: IED Model Design

    This section is fundamental and provides details on installation, GUI layout, system settings, project management, create/import/modify/export ICD/CID/IID, extract CID from SCD, and generation of TEMPLATE ICD etc., The Intelligent Creation feature greatly reduces the time and effort required to build error-free IED models. It assists in customizing data types, creation of LNs of different LNodeTypes, creation of DataSet and Control Blocks, initializing DOI values and configuring Communication parameters etc. These tasks can be conveniently completed with the help of user friendly Wizards. Batch editing of Attribute Values and Element Values is also now possible using external tools like Excel. Search Utilities allow convenient searching for project items. They use a Fuzzy search algorithm, allowing context search of documentation for each Element and Attribute.

  • Part Two: Domain Design

    This section introduces simplified high level Domain design utilizing UML technologies. Like other UML tools in the market, Domain design is based on Diagrams. Here we introduce Data Type Diagrams and Domain Diagrams. These are much like Class Diagrams and Component Diagrams in UML but more powerful and convenient. The tool will remove the need for third party Domain support. It can simplify the creation of an Edition 2.0 package for Wind Power to a one-two hour task or even faster if worked on by an IEC member who is in charge of designing this domain.

  • Part Three: IED Model Extension

    This section explains how to embed private model information into SCL without breaking any rules defined in IEC 61850-6. This capability is needed since SCL is often missing information e.g PLC logic equations and internal mappings etc., SCL usually does not address non-IEC 61850 and vendor-specific parameters configuration, all of which can be essential to running an application. Introducing this information requires model extension according to IEC 61850-6. Model Designer provides a cutting-edge, vendor-independent, flexible and programmable way to accomplish this task.

  • Part Four: IED Model Validation

    This section introduces Schema Check, Integrity Check and Semantic Check against rules defined by IEC 61850 Standards. Schema Check is the most popular feature used in most commercially available tools to confirm that SCL is error free. However experience shows that Schema checking alone is insufficient to catch many errors in SCL dynamic structures and semantic constraints. Schema Check is blind to these errors and tools from many vendors “accept” these errors. This results in IEDs arriving in production and not following rules defined in IEC 61850-6. IED Model Validation is a critical. Model Designer implements Integrity Check which can detect errors that are blind to Schema Check. Semantic Check is a feature under development and will be available in later releases.
