TLDR
In this paper, the authors present an approach for the operation of substations in which protection, control and measurement devices (IEDs) exchange operational data over a data network, for instance according to IEC standard 61850.Abstract:
The present invention is concerned with the operation of substations in which protection, control and measurement devices (Intelligent Electronic Devices IEDs) exchange operational data over a data network, for instance according to IEC standard 61850. During maintenance, commissioning and fault situations when one or several IEDs are inoperable, the data that these IEDs would have produced is substituted to ensure availability of the substation. To this effect, a dedicated substitute device is permanently installed that can take the role of any IED, and that is automatically configured out of the SCD file that describes the SA system.read more
