| Abstract | The determination of ferroresonant oscillations in circuits with voltage transformers is a highly nonlinear problem due to the possible core saturation. It is achieved with an algorithm based upon the harmonic balance method in the frequency domain. Advantages over a time domain description are discussed. Branches of solutions in relevant parameter planes can be continued beyond bifurcation points and lead to a better understanding of the stability domains of the periodic ferroresonant oscillations. The method has been extended to the study of quasi-periodic oscillations by approximation models. The theoretical principles are validated on a full scale three-phase 15 kV configuration with ungrounded neutral, in which fundamental, subharmonic and quasi-periodic oscillations are initiated by controlled current pulse injections. Experimental stability limits have been determined and yielded good agreement with the theoretical ones. The limit value of the damping resistor in the delta-connected tertiary windings of the transformers is determined by the presented method. |

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.
