“…The fault could be located with the value of action factor (AF), which defines the contributions of a single activated element, or a component that involves multiple activated elements, to the fault location process [52], and a sequential tripping strategy is proposed in [54]. This BPES could avoid unnecessary trips, due to hidden failure or overloading, by locking the tripping signals of traditional backup protection relays [53], [55], and a concept of certainty factor (CF), which can be derived from AFs, is presented in [54] to handle the uncertainties associated with the incorrect operation of protection relays or the loss of communicated information. Other wide-area backup protection schemes, using distributed line model and twoterminal synchronized phasors and their angle difference, are proposed in [56], [57].…”

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.
