| Abstract | This paper describes a new algorithm of fast distance relay based on the conception of phaselets. The principle is proposed by means of directly comparing phase difference between the operating voltage phaselet and the polarizing phaselet on the basis of new phaselet equation of transmission line and new definition of operating voltage. Additionally, the exponential decaying DC component matches the new phaselet equation as well as the power component does. The new algorithm, therefore, needs neither converting the phaselets into phasors, nor removing the decaying DC offsets. The digital algorithms of fast MHO relay and fast zero-sequence reactance relay are also presented in detail. The EMTP simulation tests associated with a simple transmission system and 500 kV transmission system in Shan Dong power system show that the new algorithms have the properties of high speed with simple calculation, and are not influenced by DC decaying component as well as the high frequency components are effectively restrained |

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.
