| Abstract | As the electromagnetic disturbance (EMD) in valve hall is the leading disturbance source in HVDC converter station. With the valve tower stray parameters taken into account, the frequency spectrum characteristic of the electromagnetic disturbance in the valve hall is investigated. To determine the stray parameters of the valve tower structure, all the conductors in valve hall are included in the electromagnetic model established by using the finite element simulator ANSYS. Based on the resultant stray parameters, the wide-frequency-band valve circuit model applicable to the electrical transient simulator PSCAD/EMTDC is established. The electromagnetic distrubance is analyzed for the two transient processes that the converter valve is conducted and cut,. Hence the general effect of the stray parameters on the electromagnetic disturbance in converter station is obtained from the frequency spectrum. The research indicates that, although the stray parameters may reduce the conducted disturbance level in converter station, unfortunately the possibility of high frequency oscillation is increased on the other hand. |

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.
