| Abstract | In this paper, a simulation model is established to investigate on the conducted mechanism in substations installed with SVC (Static Var Compensator) devices with a view to characterizing the main causes of the conducted interference. The high-frequency macro model for thyristors is established with a nonlinear time-varying resistor to simulate the switching characteristics of the thyristors. Based on the above macro model for thyristors, a concrete model of SVC including TSC (Thyristor-switched Capacitor) and TCR (Thyristor-controlled Reactor) is further proposed. In addition, high-frequency equivalent models for frequency-domain compensation of both CT and PT, based on their calibrated non-flat amplitude-frequency characteristics, are adopted to rectify the emissions levels from the SVC switching. The conducted interferences by simulations are correlated with that from on-site measurements, which indicates that the high-frequency switching characteristics of thyristors are the main causes of conducted emissions. |

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.
