SmartGridware® Java IEC 61850 IED Simulator

Extensible Java-based IEC 61850 IED Simulator

Product Overview

The SmartGridware® Java IEC 61850 IED Simulator is a user-extensible server for the simulation of IEC 61850 Server instances. It provides support for all ACSI Services as defined in the IEC 61850-8-1 MMS client/server and GOOSE/GSE profile. The simulator data and behavior is configurable through SCL ICD file and may be customized using the Mini61850 Server API or SmartGridware® Java IEC 61850 Server SDK.

Product Features


As with the IEC 61850 Server SDK, the IED simulator framework provides built-in server role support for the common IEC 61850 ACSI services such that all the user only need to provide the data and configuration through an SCL ICD file. The ICD file provides all data definitions, initial data values, server addressing and configuration of some server behavior. In order to extend the IED simulator framework, the user simply writes custom behavior modules using the SmartGridware® Java Mini61850 Server API. or SmartGridware® Java IEC61850 Server SDK.

See some of the many features below:

  • All features of the SmartGridware® Java IEC61850 Server SDK
  • Includes the SmartGridware® Java Mini61850 Server API.
  • provides default CDC behavior for many common CDCs.
  • implements state modeling and standard control processing
  • report, GOOSE, Setting Group, and other control blocks
  • text based command line interface to access/modify simulator data
  • Under Development: web-interface for simulator configuration and control
  • uses the SmartGridware® Java MMS Stack as the MMS provider

IED Simulator Examples


The following examples show how to configure and customize the SmartGridware® Java IEC 61850 IED Simulator using the Mini61850™ Server API (click to view):

IEC 61850 IED Simulator API Initialization

  Mini61850Api api = new Mini61850Api();

   // -- 
   // -- Create a new server instance with the provided options... 
   // -- 
   Mini61850Server server = api.newServer("-scl:strict SGWDeviceA1.icd -xt MySim ;


Client Association Example

   // -- Attach an association listener to handle new associations 
   // -- and association changes

   server.setAssocHandler(new AssocHandler()
      // -- authenticate an incoming association request using authentication 
      // -- info if provided. throw an exception to deny an association request.
     public String authenticate(AssocHandle assoc, 
                                String auth_info) throws MiniServiceException
         return null;

      // -- invoked when an association state changes. 
      public void associationChanged(AssocHandle assoc)


IED Control Handler

      // -- 
  // -- Set an Operation handler to process test/operate states on controls
  // -- 
  server.setOpHandler(new OpHandler()
     // -- performTest is invoked for PARAMETER, INTERLOCKING, SYNCHRO tests. 
     // --
     public boolean performTest(Op op, Object ctl_val, 
                                OPTEST op_test) throws MiniControlException
        // -- May throw a MiniControlException for failed tests
        return false; // tell the API to also perform default tests

     // -- performOperate is invoked to operate the control once all tests 
     // -- have passed. If the operate fails, the MiniControlException may 
     // -- be thrown to notify the failure for enhanced security operations. 
     public Object performOperate(Op op, Object ctl_val) 
                                  throws MiniControlException

        // -- perform actual output control here... 
        return ctl_val;
     // -- Setting the control handler for multiple controls
  }, "ExGGIO1.AnOut1", "ExGGIO1.SPCS01");
