| Abstract | In smart substation, with regard to the realization of substation area backup protection (SABP) which can execute the backup protection function for whole substation, the information communication network transmitting and sharing digital signals will undoubtedly play an important role. In this paper, the realtime performance of a smart substation's process level network, which receives voltage/current sampled values (SV) message and sends generic object oriented substation event (GOOSE) message for SABP, was studied. Firstly, the structure and function of SABP were introduced, and its demands for the communication network's working performance were proposed. Besides, taking a practical 220kV smart substation for example, the process level network's structure scheme was designed for SABP, and then the time-delay characteristics of the messages including both SV and GOOSE were estimated. According to the research results, under the condition that the actuating signals of SABP come from the process level network, the time-delay characteristics of this information communication network can satisfy the requirement for the rapidity of action of backup protection. In the end, some measures which may help to reduce transmission delay further were presented in brief. |

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.
