| Abstract | In this paper, the mathematical model of STATCOM based on space vector theory is presented. The voltage equations are transformed into the synchronous rotating reference frame (dq-axis). The relationship between STATCOM parameters and stability, transient and steady state performances are determined. Stability investigation with Routh-Hurwitz criterion indicates that the STATCOM is a stable system and the numerical values of resistors, inductors and capacitors in the STATCOM equivalent circuit have no effect on stability. Steady state analysis reveals that the size of DC capacitor does not affect STATCOM steady state performance. The dynamic performances in terms of varying parameters are displayed in the forms of both root locus plot and Bode plot. The behavior of STATCOM for voltage regulation was simulated with ATP-EMTP. The case study was made on a 230 kV radial system. With simple PI controllers and modulus optimum design criterion, the voltage response to 3% step change of the reference showed approximately 5% overshoot and the settling time was within three cycles |

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.
