Abstract | Summary form only given, as follows. This paper presents a comparison of performance of traditionally used synchronous condensers (SCs) at inverter side HVDC terminal and a novel inverter control method. The novel controller has earlier demonstrated good responses with very weak inverter AC systems and widely changing AC system parameters. The aim of this research is to study if it is possible to offer adequate replacement for SC at weak HVDC-HVAC interconnection points. The simulation results on an actual HVDC system show excellent small signal responses, but the main obstacle for the application of the new control method could be increased probability of commutation failure. Subsequent tests show that in order to keep the same commutation failure probability, half of the SC must be maintained in normal operation. Further SC can also be disconnected, when the new control method is employed, however the nominal operating angle has to be somewhat increased. The cost benefit study is performed to analyse the financial benefits of the proposed project. It is concluded that although the benefits ire evident for the new HVDC links, the proposed replacement of SC may not be justifiable for the existing links. |

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.
