| Abstract | In this paper, numerical evaluation of ionized field quantities associated with HVDC corona is carried out using charge simulation technique and integral algorithm. And considering the surface charge of each rectangle patches and simulation charge inside the HVDC conductors as unknown variables, a set of quadratic equations are developed on the base of the potential at the boundary, the corona onset field values at the coronating conductor, and continuity of current on each patch. By Using the NGB (Globally convergent inexact Newton method) method the quadratic equations is solved, and the electric field intensity, distribution of space charges and ion current density can be obtained. Different cases of the single conductor above ground are considered, and the computed results show good agreement with available experimental data. Finally, the method is successfully applied to calculating the electric field and the ion current density of a realistic HVDC transmission line. |

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.
