Wide-Area Protection and its Applications - A Bibliographical Survey

Modern power systems are continuously developing to large and interconnected ones. The power industry restructuring and the reduced investment in transmission system expansion make power systems operate closer and closer to their limits, and hence lead to larger possibility of fault outages than before. Therefore, the protection and control in power systems become more and more important as well as complicated. On the other hand, the continuous technological development in communication and measurement accelerates the occurrence and applications of wide-area protection, a kind of advanced protections based on wide-area measurements. The blackouts happened in North America as well as other countries in the past few years also provide more and more incentive for scientists and engineers in the power system circle to devote to the study on wide-area protection and control systems. In this paper, a comprehensive bibliographical survey is made on recent development in this field, and the survey is done from seven relevant aspects
