| Abstract | In squirrel-cage induction generator (SCIG) powered micro-grid, continuously variable reactive power (CVRP) should be provided to stabilize the grid voltage when load is constantly changing. This paper proposes a novel CVRP compensator, which name is static VAR compensation magnetic energy recovery switch (SVC-MERS). Comparing with static compensator (STATCOM), the proposed device has some advantages in line frequency switching, small dc-capacitor and robustness. To begin with, operation principle of SVC-MERS has been briefly described in this paper. Secondly, optimal direct-voltage control (ODVC), which aims to broaden the reactive power compensating range, is proposed and verified by simulation in PSIM. It also has the advantages of sinusoidal output-current waveforms and restrains dc-capacitor voltage. Thirdly, a three phase SVC-MERS has been designed with delta connection and applied to voltage regulation in a 15kW SCIG powered micro-grid. Then experiments have been finished under different load conditions. Finally, experimental results confirm the conclusion. |

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.
