| Abstract | The precision of the voltage phase angle measured by the PMU (Phasor Measurement Unit) can well meet the need of power system analysis and control. A new controller is proposed for power system stability, which can linearize its nonlinear state equations by online tracking of the state variable with the help of PMU, and complete an objective control strategy that forces the system state into a desired objective. The control method is called Linearization through Observation (LTO) for a tracking objective control, which is proposed in this paper. Application of the LTO method on Tracking Objective Excitation Control (TOEC) is also presented in this paper. An example of a single machine infinite bus power system is given to show the effectiveness of the proposed controller. The simulation results show that TOEC is superior to Linear Optimal Excitation Control (LOEC) in both enhancing power system stability and improving power system dynamic quality. Meanwhile TOEC has the ability to force operation state into a desired Objective, which will be very useful in the coordinating control of a large power system. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
