| Abstract | In this paper, a new sag detection algorithm for a dynamic voltage restorer (DVR) is proposed. The proposed detection algorithm has a hybrid structure composed of an instantaneous value comparison part and a peak variation calculation part. The peak variation calculation part calculates the fundamental and harmonic components by using the discrete Fourier transform, and has a constant detection response regardless of phase angle at which sag occurs. The instantaneous value comparison part compares a measured voltage value with a reference value, which is compounded by the harmonic components obtained from the peak variation calculation part. Therefore, the proposed detection method shows a fast and robust response even under the distorted grid voltage condition, which is polluted by harmonics. The proposed method is verified by simulation and experiment with 10kVA DVR prototype. |

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.
