Abstract | Some experiences on the use of state estimation methods for identifying the parameters of transmission lines are described. As a result, an algorithm to estimate the parameters of transmission lines and transformers is proposed. It uses a set of measurements for different operating conditions; these measurements can be obtained from historical records. Using measurements of voltage and active and reactive power flows on both ends of a given line, an estimator is built that can compute the parameters of a line, independently of the condition of the rest of the system. In a similar way, it can compute the parameters and, more importantly, the position of the tap of a transformer. The method has been used to identify the parameters of all lines and transformers for the IEEE 30-node system. The performance of the estimation process, as proposed, is independent of the number of lines to be identified as long as there is enough variability in the linepsilas loading, so the size of the system is not relevant, as long as there are enough measurements. |

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.
