| Abstract | Detecting and classifying transient signal have been concerned with by researchers recently, at home and broad. Especially, there are still many difficulties in classification. Based on the PSCAD/EMTDC model of a practical 500 kV transmission line set in part II, six transient signals are simulated, such as breaker operation, capacitor switching, single-phase to ground, primary arc, and lighting strokes with and without fault. As its definition is given in this paper, multi-scales wavelet energy spectrum entropy, combined with neural network, has excellent ability in transient signal classification, especially between fault and non-fault ones. The faulty phase selection of short-circuit is completed on the base of wavelet energy spectrum entropy and fuzzy logic defined in part I. Experiment results show that wavelet energy spectrum entropy of transient signal is characteristic, and BP neural network is efficient in classifying, and fault phase selection using fuzzy inference is effective too. From the research, it is obvious that wavelet entropy application has a bright future in electronic power system. |

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.
