“…To our knowledge so far not much research has done to examine the performance of Gigabit Ethernet within the substation. LAN congestion scenarios for Ethernet based substation is analyzed [7] by Tengdin but it differs from our work in several key aspects such as no consideration for shared process bus, absence of industrial protocols (such as TCP/IP and UDP) specified by Internet Engineering Task Force (IETF) over Ethernet, and also there is no consideration given to background traffic load for accurate result. Brunner [2] examined role of Ethernet in the SA.…”

Communication architecture for substation automation is one of the challenging and subtle tasks to address in order to visualize the substation into digital world under the umbrella of IEC61850. Communication paradigm for substation automation demands critical importance because of two reasons; as communication arena is changing day by day so it is convenient to opt for something that is simple to deploy and incur a less cost in terms of time and asset when migration is to be considered since data-intensive applications drive the incremental demand for bandwidth as per growing need with the expansion of concerned network and last but not least the interoperability as it is one of the core constrained put by IEC61850 for substation automation. So it is viable to consider Ethernet as the most promising solution for the communication architecture of substation automation as Ethernet technology has changed the trend of communication network because of its availability, efficiency, and cost effectiveness on the other hand interoperability is assured based on the proven and highly deployed industrial Ethernet. This paper presents analysis and the crucial need for the deployment of Gigabit Ethernet in the substation and also presents how Ethernet technology can help in the substation automation as a long run solution in the changing arena of communication as Ethernet is one of the most pervasive communication technologies. In the end we have performed simulations in NS-2 to prove that our suggested communication paradigm is optimal in various regards by keeping into consideration the constraints imposed by IEC61850.

“…F. Engler et al [10] have proved the real-time performance of SAS can meet the standard requirements [11] by doing the feasibility studies of IEC 61850. LAN congestion scenarios for the Ethernet-Based substation have been examined by Tengdin et al [12]. However, any process bus is not included in the examined substation.…”

Design of Hardware Setup Based on IEC 61850 Communication Protocol for Detection & Blocking of Harmonics in Power Transformer

In this paper, the authors have developed a hardware model for blocking even and odd harmonics of a power transformer. In the proposed hardware model, intelligent differential & over-current relays are used for the blocking of harmonics of a power transformer. The harmonic restraint function on the differential relay (7UT61) prevents the relay from tripping during transformer magnetizing inrush current. However, the over-current relays which are used for back up protection does not have a harmonic restraint element, and over-current relay trips due to magnetizing inrush current, causes unwanted interruptions and power failures. The establishment of harmonic blocking scheme for over-current protection in power transformers is an important finding of this research study. IEC61850 standard-Based GOOSE (Generic Object Oriented Substation Event) applications used in power transformer protection for fast detecting and clearing of faults is an interested study presented in the proposed work.

The end-to-end delay of protective relaying data flow in a substation was studied by dynamic simulation modeling technology. The distribution characteristics of protective relaying data flow and the constitution of the end-to-end delay of messages were analyzed. The simulation model for digital communication between protective relaying equipment and monitoring equipment of interval layer was suggested. The end-to-end delay of protective relaying data flow in different network configurations was analyzed. It is found that the size and interval of the data frame, utilization of the link background and protocols of higher layer are key factors of real-time performance. Detailed analysis results are presented. A proposal for network configuration is suggested to reduce end-to-end delay of protective relaying data flow.
