| Abstract | Due to the proliferation of distributed power systems, renewable energy sources and systems working in islanding mode, the issue of grid frequency variations has come to be an important topic. In this paper, two single-phase and one three-phase phase-locked loop methods are studied. The resulting PLLs algorithms are completely developed in the discrete plane in order to be directly applied on digitals systems as DSPs or FPGAs. The objective is to get PLLs as simple as it can be accomplished, with the purpose to reduce the computing time. Weak network supply systems and systems working in islanding mode have usually poor short circuit capacity. In addition, the source impedance leads to a much polluted voltage supply signal in the presence of nonlinear loads. In order to get an appropriate synchronization, a Rectangular Windows Filter (RWF) is employed as a noise rejecter. For unbalanced systems, two approaches to get synchronism are presented, where the unbalanced system can be due to sensors failures or power problems in the grid voltage. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
