| Abstract | This paper proposes a new method for estimating frequency and harmonic parameters in power system. The method is based on recursive wavelet transform and uses the wavelet transform coefficients of voltage and current signals. The complex magnitudes contain the phasor information of interest needed to estimate the frequency and selective harmonic components. This approach is capable of accurately estimating the frequency and selective harmonic parameter utilizing one cycle of an input signal. It features fast response and achieves high accuracy over a wide range of frequency variation. Effects of the sampling frequency and data window size on the algorithm performance are investigated. The two parameters can be selected to meet desirable applications requirements, such as fast response, high accuracy and low computational burden. Simulation results demonstrate that the proposed method achieves good performance. |

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.
