SUBNET Releases New Software Tool to Simulate Substation Relay Data Communication

SUBNET Solutions Inc. | March 2, 2010

SUBNET SEL Relay Data Emulator™ helps substation integrators and utilities effectively and easily bench test substation systems while eliminating the risk of a disturbance.

SUBNET Solutions Inc. (SUBNET) recently released a new substation utility software tool to help integrators, engineers, technicians and other utility personnel build better substations.

SUBNET SEL Relay Data Emulator is a versatile software application that simulates utility-specific SEL relay data communications. This simulated data is used to test communication networks, commission substations, check configurations, test firmware and more.

Traditional elements of substation bench-testing are either risky, costly or both. Testing is either done in a live substation environment with potential to cause disturbances, or the test-equipment is expensive. SUBNET SEL Relay Data Emulator enables utilities to simulate all of their SEL relays for the cost of a single relay. With SUBNET SEL Relay Data Emulator, testing can be done safely, while eliminating all potential for a power outage.

“SUBNET SEL Relay Data Emulator was created for those tasked with building, maintaining and evolving electrical substations” comments Trevor Hill, Product Manager with SUBNET. “SUBNET’s business is based on making substations more intelligent, and we know the cost and struggles utilities face testing substation integration systems. Simulating your existing SEL relay protocol communications is quick and easy. Users can simulate the communications of hundreds of different SEL relays for approximately the cost of one relay.”

The SUBNET SEL Relay Data Emulator is available as a software application that can be run on any Windows®-based laptop or PC. It features built-in configuration wizards, message logging, and easy-to-use familiar interfaces. The tool is also available as a complete hardware and software solution to enable users to simultaneously simulate up to 25 SEL relays.
