Abstract | In this paper a Posicast controller is designed to improve the power system stability containing the transient and the small signal stability. Unlike most of the recently published excitation control schemes, Posicast control is an unsophisticated and easy to implement control method that can effectively improve the stability of the system without increasing the complexity of the control system. The proposed controller is simulated under several large and small sudden 3-phase faults occurred in the different parts of the lines. It is also shown that the proposed controller increases the capability of the system in damping the oscillations caused by changing the exciter reference signal. In other words only one controller is used to improve the transient and small signal stability as well as the voltage stability. The results from extensive time domain simulations using MATLAB/Simulink demonstrate that the offered control strategy is superior to the conventional excitation control methods and can improve performance of the system in the all testing conditions. A performance index is also used to validate the effectiveness of the proposed controller in improving the system stability. |

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.
