Reliable protection, communication and control are the key features of a digital protection scheme in a utility substation. Microgrid is an alternative solution of installing long Transmission & Distribution lines could be cost prohibitive. There are number of Intelligent Electronic Devices (IEDs) which could find applications in controlling and monitoring of power network in a Microgrid set up...
Digital Communications amongst multi-vendor intelligent electronic devices (IED's) is an important feature of a substation automation system (SAS). Measuring the propagation delays and assessing the interoperability performance of IED's in an Ethernet architecture play a critical role in the protection of important substation assets. Early detection of the loss of data packets in a star connected...
Communication between intelligent electronic devices (IED's) is an important feature of a utility substation automation system based on IEC 61850. Time critical information related to fault and overcurrent, under frequency messages for substation automation system (SAS) and the use of IED's from multiple vendors, has opened up issues related to a reliable protection system within the high voltage...
