Abstract
SA is said to be improving protection performance due to the Generic Object Oriented Substation Event (GOOSE) messages that can be rapidly transmitted in a network to perform protection and other functions. Based on the fact that the GOOSE messages only occupy three layers of the Open System Interconnection (OSI) model, in contrast to hardwired relay contacts which must traverse additional communication layers; the GOOSE messages are claimed to be faster than hardwired contacts on the relays. The objective of this research is to prove whether the GOOSE messages are indeed faster than the hardwired contacts. The main questions that guide the thesis are, firstly, is the speed of GOOSE messages always faster than the speed of hard wired contacts of the relays? If not, what are the factors that can affect the performance of GOOSE messages? Secondly, is a nonconventional Breaker fail function using GOOSE messages possible, without using a conventional bus zone panel? Additionally, the research sought to establish the interoperability of IEDs from different vendors using the GOOSE message system.
