Abstract

There are various Intelligent Electronic Devices (IEDs) placed in a Substation Automation System (SAS) based substations. These IEDs are meant for performing the respective functionalities that they are intended for, which includes protective relays, transformer tap changers, Bay control units, RTUs, Protocol Converters etc., present in a substation. These IEDs are also required to communicate with each other and that may include IEDs from various other manufactures also. This paper provides brief details of the IEC 61850 standards and the test procedures formulated by UCA International Users Group (UCA IuG) used for testing Server IEDs which are used to validate for their conformance to the standard. This paper also helps in addressing the interoperability of IEC 61850 based IEDs among the multivendor solutions subjected to conformance testing and are used in the Substations.
