The goal of this report is to evaluate the possibility of defining a common format for IED configuration data. This common format should allow the exchange of configuration data between different applications like coordination programs, test programs, databases, and setting software. In many numerical relays, programmable logic is also part of the IED configuration. For this report the programmable logic is excluded and needs to be addressed later. The report will focus only on one medium complexity function, the distance protection function (IEEE C37.2, Function 21), to prove whether the goal is achievable or not. The working group assumes that if a common format for a distance protection function can be described, then all other protection functions can be modeled as well.
