Abstract | Conventionally distribution substations utilise hardwires (copper cables) for achieving different operational requirements such as interlocking, inter-tripping and automatic transfer systems. The latest substation communication standard IEC 61850 introduced a new method for horizontal communication of digital and analogue messages between devices in the substation called GOOSE or Generic Object Oriented Substation Event. In addition, IEC 61850 adopted seamless redundancy protocols, namely PRP and HSR, to encourage the utilisation of GOOSE communication in high-dependency applications. Here, the performance of GOOSE communication is assessed under different background traffic conditions in an HSR redundant network. This is achieved by utilising a data quality analyser to inject Ethernet ARP packets simulating background traffic. The network also includes an Ethernet switch, time server, laptop and three IEDs or Intelligent Electronic Devices. The IEDs are natively supporting IEC 61850 with HSR protocol, and configured to exchange GOOSE messages. Test results show GOOSE communication is affected by the traffic, but the severity of the problem, i.e. delays and losses in the communicated messages, depends on the level of traffic, as a percentage of the bandwidth. Tests also show redundancy enhances the overall network reliability via dual paths, limiting the effect of background traffic on the communicated messages.. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
