| Abstract | A case study on the Australian equivalent system - recently adopted as an IEEE benchmark for stability studies - is presented here to illustrate power oscillation damping through HVDC links. Wide-area signals are used for supplementary modulation of the HVDC power order driven through a multi-variable controller. The test case is set up in DIgSILENT and benchmarked against the standard results. Linearized model around the nominal condition is obtained by using subspace identification on a set of measurements derived out of probing the system through the HVDC link. Modal analysis is carried out to identify a set of appropriate feedback signals for the controller. Pole-placement technique is used to design a multi-input, single-output (MISO) controller in two different frameworks - i) observer driven state feedback and ii) optimized lead-lag compensators. The effectiveness of HVDC modulation for power oscillation damping is validated through eigen-value analysis and non-linear simulation (in DIgSILENT) over a range of operating conditions. |

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.
