| Abstract | Electromechanical oscillations in power systems often exhibit poor damping when the power transfer over a corridor is high relative to the transmission strength. Traditional approaches to aid the damping of power system oscillations include the use of power system stabilisers (PSS). Off late, the capability of flexible AC transmission systems (FACTS) controllers in damping power system oscillations has been explored and proven. Unlike PSS, for a remotely located FACTS controller, it is desired to extract an input signal from the locally measurable quantities at the controller location. The responsiveness of the input signal to the swing modes to be damped-commonly known as "observability" is an important criteria for input signal selection. Analysis of four basic input signals-line current, active power, bus voltage and bus frequency for an example single machine infinite bus (SMIB) system installed with a static VAr compensator (SVC) shows that line current signal enables substantial positive damping to be attained for all operating conditions. This is confirmed by eigenvalue analysis and dynamic simulation using MATLAB. |

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.
