Abstract | The goal of this work is to present a developed adequate model that will allow analyzing, dimensioning and control of auxiliary DC installations in power plants, first of all from the protection device point of view. This paper deals with risk of power system blackout caused by auxiliary DC installation failure. In the past, failure of auxiliary DC installation has been caused by wrong selectivity of protection devices. However correct selectivity calculation is based on short-circuit current calculation. For this reasons it has to be made a general mathematical model of auxiliary DC installations in power plants and substations that correspond with laboratory results of short-circuit current test. It was concluded that the transient state during short circuit has to be taken into account and mathematical model of auxiliary DC installations in power plants and substations should include not only resistances, but inductances and capacities of auxiliary DC elements as well as the active network in front of the rectifier. The essence of this work is to suggest changing of present IEC standard 61660 - "short circuit currents in DC auxiliary installations in power plants and substations" that does not correspond with present technology used in auxiliary DC installations. Based on that hypothesis an original program package was developed and used for analyzing and dimensioning auxiliary DC installations in power system. The results obtained by means of the program package are relevant for dimensioning all elements of auxiliary DC installations, particularly when protection devices are considered. |

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.
