| Abstract | This paper presents a set of equations for line commutated HVdc systems that can be used to calculate the main voltages and currents of positive or negative sequence on the ac side of the rectifier or inverter and to calculate the main voltages and currents on the dc side that are related to one ac system background voltage harmonic of positive or negative sequence. Furthermore, the frequency-dependent impedances of a line commutated HVdc system on the ac or dc side can be derived. It will illustrate how the converter impedances on both sides are related via an impedance transformation function, which is the product of the transfer functions for currents and voltages. The equations for the impedances differ from those given in a previous IEEE paper, especially with respect to the representation of the impedance for the converter transformers. It did, however, lead to similar results for the CIGRE benchmark model. In order to distinguish between a monopolar and bipolar scheme, the equations take the numbers of poles into account. Furthermore, six- or 12-pulse arrangements 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.
