| Abstract | This paper presents a novel anti-islanding (AI) detection algorithm for three-phase (3Φ) grid-interface converters in distributed generation systems. A generic phase-locked loop (PLL) model by considering the converter interaction with grid is proposed. And the frequency positive-feedback mechanism is proposed to predict the frequency behavior of the grid-interface converter system, especially under the islanded condition. Many of the frequency-related behaviors can be well explained and the crucial system parameters, which impact the PLL stability and non-detection zone (NDZ), can be also quantified by the proposed model. Based on the model, a novel anti-islanding detection algorithm based on the frequency stability is proposed to effectively detect the islanding event under the worst loading condition, achieving ideally a zero NDZ. The proposed algorithm features a small impact to the converter system operation as well as a easy implementation. |

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.
