| Abstract | In order to improve reliability and resist interfere when grid voltage occurs fluctuation and distortion, and further reduce the cost for the grid-connected inverter, the control strategy is presented based on phase lock loop(PLL) and virtual grid flux without grid voltage sensors. The virtual grid flux vector orientation, d-axis current and q-axis current close-loop control are used based on the mathematic model in synchronous rotating reference frame for the grid-connected inverter, which achieves the decoupling control for d-axis current and q-axis current. The active power and the reactive power are independently controlled by q-axis current and d-axis current. Simulated and experimental results show that the grid-connected inverter based on PLL and virtual grid flux has a good dynamic and static performance. So the feasibility and correctness for the control strategy is verified. |

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.
