IEC 61850 - The Impact on Testing

The application of IEC 61850 introduces several new issues for testing substation devices. The most obvious change is the different way of "wiring" to obtain the signals. But there are other issues that change the way of testing, such as configuration. Signals and data traffic of different nature have to be regarded, such as real time peer-to-peer messaging (GOOSE), digitized data from CTs and VTs (sampled values), and client/server communication for SCADA purposes. The availability of machine readable, system wide configuration information opens new aspects for an extended testing scope (system testing). More
