| Abstract | Current developments towards Cyber-Physical Energy Systems (CPES) [1] requires the close integration of traditional power grids and appropriate Information and Communication Technology (ICT) infrastructures. Driven by additional requirements of future monitoring and control, increasing amounts of data have to be handled to ensure safe operation of the power grid and to maintain frequency stability. Therefore an appropriate ICT infrastructure becomes crucial for enabling fast and reliable transmission of time critical messages such as switching commands. This paper provides an evaluation on the real-time capability of the communication network in three scenarios analysing different levels of the power grid infrastructure: within the substation, between neighbouring substations and between a substation and the control centre. Communication is modelled according to the standard IEC 61850 using both simulation and the analytical approach of Network Calculus. Thus, we determine mean values as well as worst-case bounds on the delay of messages, evaluating the impact of varying network and traffic conditions. The results highlight the applicability of IEC 61850-based communication as a holistic solution for the power grid, supporting advanced tele protection and remote control applications. |

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.
