| Abstract | This study explores the feasibility of applying inductive filtering technology to high-voltage direct-current (HVDC) transmission system since only filtering in the net side may lead to a lot of harmonics in the converter transformer. Basic principles of inductive filtering technology are presented and detail analyses are discussed from the aspects of filtering, vibration, commutation, short circuit, and AC system strength. Simulations and experimental tests show that when inductive filtering technology is applied, most of the harmonics do not enter the net side of the converter transformer but are directly filtered in the valve side. Thus, the harmonics flowing in the converter transformer reduce and the vibration of the converter transformer becomes smaller. The commutation reactance decreases sharply which greatly reduces the overlap angle and improves the commutation characteristics. Moreover, the short-circuit reactance almost keeps unchanged and the short-circuit characteristics do not deteriorate, and so the requirement for the AC system strength is much lower. This study finally concludes that applying inductive filtering technology to the HVDC transmission system is feasible, based on a successful engineering application in the high-power rectifier system. |

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.
