| Abstract | Voltage source converters based HVDC (VSC-HVDC) systems involving overhead transmission lines are prone to severe over-currents and over-voltages during dc line faults. This necessitates the operation of the system with some kind of protective devices to overcome the effects of dc line faults. Due to uneconomical and non availability of commercial DC circuit breakers the present day VSC-HVDC systems find applications only in back to back and/ or underground cable transmission, power ranging in the order of 400 MW. In the present work, the application of superconducting fault current limiter (SCFCL) along with chopper controlled resistors (CCR) is proposed to overcome the effect of over-voltages and over currents. The VSC-HVDC system is analysed with the high voltage and high current (110 kV, 2.8 kA) resistive SCFCL and the CCR in PSCAD/EMTDC environment. The results of analysis for various ac and dc fault conditions are quite encouraging. |

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.
