| Abstract | In allusion to fault location failure on wide area travelling-wave-based fault location methods caused by the indeterminate shortest transmission path of initial travelling wave and the inaccurate travelling wave velocity, this study proposed a novel fault location method for complex transmission grids based on the time difference of arrival of wide area travelling wave. Firstly, the shortest transmission path in the loop network is determined online by using the time difference of arrival of the initial travelling wave measured at both ends of the fault line. Then, the travelling wave velocity and accurate fault distance are calculated by fusing arrival time of wide area initial travelling waves via the least-square estimation. The phase current travelling wave is used for the proposed method, and the S transform is used for detecting the arrival time of phase current travelling wave at the Nyquist frequency. The proposed method avoids the phase-mode transformation and the matching between the actual fault condition and the pre-determined shortest transmission path. The proposed method can also exactly calculate the fault distance without obtaining the travelling wave velocity. The performance of the proposed method is verified by the power systems computer aided design/electro magnetic transients in DC system (PSCAD/EMTDC) simulation results. |

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.
