A behaviour evaluation of network traffic in a power substation concerning GOOSE messages

Abstract

This paper investigates the influence of a Denial of Service (DoS) overload on the transfer time of GOOSE (Generic Object Oriented Substation Event) messages. This paper was conducted based on a testbed set up in order to carry out the experiments that evaluate the behaviour of transfer time of GOOSE messages during IED's bandwidth occupation. This practical apparatus mainly consists of two IEDs, Ethernet switches, IBM personal computer, fiber optic cables, GPS Clock, unshielded twisted pair cables, as well as support software. The results provide a benchmark for the transfer time of GOOSE messages between different devices. These times are important to be establish considering protection coordination in power systems.

Analysis of GOOSE message and the engineering application for GOOSE message in the intelligent substation

“…The application of GOOSE in the process layer of the intelligent substation is mainly for the purpose of ‘protecting the trip’ and other important messages, which must be transmitted to the destination in time within the specified time. Therefore, it is of great significance to and it has a practical value to study and analyse GOOSE and SV messages in the IEC61850 standard environment [8–11].…”
