| Abstract | In order to eliminate the effects of electromagnetic coupling and parameters uncertainty of four-parallel transmission lines on the same tower for fault location, this paper proposes a novel parameter self-adaptive fault location scheme of four-parallel transmission lines on the same tower. Firstly, a decoupling method of four-parallel transmission lines is proposed to eliminate the effects of electromagnetic coupling of four-parallel transmission lines. Secondly, constructs a set of linear parameters self-adaptive equations based on the parallel component before fault to obtain the mathematical expressions of line parameters. Finally, on the basis of decoupling method and transmission line parameters self-adaptive method, the fault location observation equations based on the circulation components after fault are established to realize a data-independent fault location scheme of four-parallel transmission lines. As a set of linear formula for the line parameters is derived and the mathematical expression of fault location is given, the proposed method has high computing speed and precision. In the end, using ATP/EMTP, a four-parallel transmission line model is constructed for simulation. The analysis results demonstrate that the proposed fault location scheme is accurate. |

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.
