Abstract | Distributed Generation (DG) source in a power system is used in direct and indirect modes. Direct mode includes the application of DG during source outage, for voltage profile improvement, etc. In the indirect mode, DG is used in conjunction with a static compensator like Unified Power Quality Conditioner (UPQC), Dynamic Voltage Restorer (DVR) for improvement of power quality. The purpose of the DG in the indirect mode is, it supplies real power required by the static compensator: either for the compensator itself (for internal losses) or to supply to the grid /load connected to the compensator. This paper deals with indirect mode of DG. And the static compensator used is UPQC. The overall system is named as Distributed Generation based Unified Power Quality Conditioner (DGUPQC) and is proposed for compensation of voltage sag and reactive power at the supply/source and load side respectively. The above said operations have been implemented on a (novel) mathematical model of the DGUPQC; which is a Multi-Input-Multi-Output (MIMO) system. The control of DGUPQC, comprises of speed, DC link voltage, and injected voltage/reactive power control, and is performed by conventional Proportional-Integral (PI) controllers. Simulation studies have been carried in Matlab/Simulink and the results shows excellent performance of the DGUPQC. |

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.
