Design MIMO Switch Architecture Based IEC 61850 Standard of Substation Automation Systems

摘要

Recently, there has been a tremendous change in the development of many protocols in electrical substation automation such as robust communication among control centers (GOOSE). It is a challenge to implement critical time operation such as tripping based on GOOSE protocol when the protocol is not tested in a wide area multi-substations environment. Another reason is the function of the packet forwarder may fail under a very high traffic condition with the constant generation of GOOSE packets due to multiple events. This study investigates the performance of packet forwarder in terms of packet loss under different models configurations. The investigations carried out on various switch configurations and architectures to reduce the number of dropped packets. The results showed that the architecture of two-switch system is the best performance in which the packet loss can be reduced by 2.9% in comparison with two buffer switches and 11.8% in comparison with the to original standard.
