dc.description.abstractOver the course of the last decade, IEC 61850 has become the leading standard for electrical substation automation the world over. This thesis presents the work done towards implementing an IEC 61850 sampled values based line protection Intelligent Electronics Device (IED) on a desktop computer. This IED is capable of subscribing, decoding and processing the sampled values published by a source to be used in line protection algorithms. The novel hybrid line protection algorithm implemented in the IED combines a distance protection scheme with a transients-based unit protection method that uses sampled values complying with IEC 61850-9-2-LE. Application of the line protection relay for protecting a series compensated transmission line was examined using hardware-in-the-loop simulations. Results indicate that (i) the implemented algorithms are robust and reliable, and (ii) the class of transients based protection algorithms examined in this thesis can be successfully implemented with IEC 61850 sampled values.en_US
