| Abstract | Electrical Supply Substations (ESS) in modern railway DC systems are widely equipped with 24-pulse rectifiers, because such a converter provides a good promise between dc-side voltage ripple and ac-side current harmonic content. Accurate determination of transient dc-side short-circuit current is important for design of protection devices and power equipment. Firstly, the mode of short-circuit operation in 24-pulse converter is analyzed; then, the general method to calculate the short-circuit current is obtained by combining both the impedance calculation and short-circuit current formula in short-circuit state; finally, this method is simulated to compare with the transient and steady-state short-circuit currents with its own parameters of the transformer in Matlab. The figure shows that two curves are overlapping, so it proves that the method in this paper is correct. |

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.
