September 2010 Issue
This immediately creates a barrier that may be difficult to overcome. It can stop us from looking carefully and trying to find out if it really is so different and what we can apply from what we know to the new world we live in. Many things are just a matter of perception. What is different is the technology that is being used to implement the same things that we can do with copper wires, ... More

Lessons Learned

Experience with Testing and Configuration of IEC 61850 Multivendor Protection Schemes

A test device must be able to subscribe as well as publish GOOSE messages. The IED being tested will publish or send a GOOSE to tell the breaker to trip. The test device subscribes to the GOOSE issued by the IED under test and reacts to it according to the test procedure. Some of the challenges facing the testing of IEC 61850 include the lack of knowledge that protection specialists hav... More


Evaluation of Protection System Performance Using DFR and Relay Comtrade Files

The protection analysis system was developed on top of a previous work. Introduction: Some distribution utilities in Brazil own and operate transmission assets rated 138 kV and bellow. The right-of-way paths in metropolitan areas are optimized by installing parallel lines, which raises protection selectivity problems. In fact, these lines usually supply high density load centers and non-sele... More


Implementing Firewalls for Modern Substation Cybersecurity

Historically, Ethernet operated with the idea that all devices on a network are trustworthy. That is, networked devices can be trusted with any information they receive from the network, and networked devices will not attempt to cause harm to the network or other networked devices. The idea that all Ethernet devices are trustworthy worked well when there was limited access to computer ne... More
