Abstract

Our aim is to show the results from a mathematical simulation of the behavior of a differential protection algorithm for power transformers compared with the loss of the time synchronization signal in the process bus according to IEC 61850-9-2. Described herein are an original model for simulating the samples in the process bus, a proposed algorithm for differential protection of power transformers adapted for protective relays operating with process bus according to standard and response analysis of the protection algorithm from this loss of sync.
