Abstract | In the last year the automation systems in power substation start to rely on networks thanks to the introduction of the IEC 61850 standard. Besides, it generates a general interest on synchronization also in the field of substation automation systems. In fact, timestamping of critical events or synchrophasor measurements can have a great advantage from distributed synchronization protocols like IEEE 1588. This paper analyzes the current situation and proposes new architecture for the test of IEEE 1588 solutions before introduction in the market. The focus is mainly on compatibility with real existing systems and its goal is the performance comparison of different implementations. First experimental results on real substation automation system show a great cabling reduction and a simplified maintenance in the IEEE1588-based systems. On the other hand, the synchronization performance are slightly worse: the maximum time difference among clocks of the system is about 80 ns for IEEE1588 with respect to 15 ns of typical IRIG-B-based system. |

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.
