| Abstract | A new approach to estimate the power system frequency and signal components using wavelet transform is proposed in this paper. The wavelet function is expressed by the power series and is able to be performed by the z-transform, which can shorten the estimating time of the signal frequency compared with the general convolution integral. The fundamental frequency (60Hz) or the harmonics frequency (300Hz) of the signal is quickly estimated and components of signal are extracted by the proposed method. The online estimation by the proposed method is successfully achieved in the experiment using the DSP system. And the characteristics of the estimation method by the parameter changes are confirmed. |

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.
