Previously held Thursday, January 25, 2024 at 10am ET


In a traditional substation with copper wires, testing is straightforward. You can isolate the section to test attempting to avoid effecting the entire system, hook up the test equipment and physically perform a manual test. However, this involves a tremendous amount of manual effort, intervention & modification of the entire system which is ultimately inefficient and creates a high risk of multiple safety issues.


With the introduction of IEC 61850 into a substation, there are many features defined by the standard to eliminate the manual effort with Virtual Isolation.  This will increase efficiency & accuracy of testing while greatly reducing safety risks.  The transition from physical isolation to virtual isolation requires new tools to visualize what signals are being processed, injected by test equipment, or blocked.  Automated test sequences performed by these tools can be validated on a simulated substation and prove that no unexpected results occur.  Portions of the simulated substation can be replaced by critical protection equipment to verify they will respond correctly to signals generated by both the test tool and other IEDs in the simulated substation.


What you'll learn: 

  • How to increase confidence in Virtual Isolation testing before entering the substation
  • IEC 61850 features for managing virtual isolation
    • Different testing modes of an IEC 61850 Logical Node
    • How to manage reception of simulated GOOSE streams
    • Understanding the impact of blocked behavior
  • How LGOS is used to monitor the status of GOOSE subscriptions
  • Real life examples of how to perform virtual isolation testing using 61850 Test Suite Pro on a simulated substation in Distributed Test Manager (DTM)
    • Monitor real and simulated signal flow
    • Set test mode in IEDs
    • Configure IEDs to receive a simulated GOOSE stream
    • Publish simulated GOOSE Streams
    • Identify what signals are being processed, injected by test equipment, or blocked
    • Automate test setup and validation

Who should attend this course: 

  • Protection & Control Engineers/ Managers
  • Maintenance personnel
  • System Integrators
  • Software engineers/managers
  • Substation Field Technicians
  • Anyone that is open to adopting a standardized process to save time & money
