Abstract The future smart power grid where Distributed Generations (DGs) are highly integrated and self-healing is required is intended to provide reliable and quality power in economic and environmentally friendly manner. This vision of the future power grid calls for a different solution in power system protection. This demand arises from the dynamic condition of the future Smart Grid, which is why a large number of protection techniques and methods have been researched and implemented over the years. Especially, the research on adaptive power protection techniques is immensely growing, as it is very desirable for the power system to change its own protection settings in real-time according to the system operating states and conditions. This literature survey presents a number of power system protection techniques being implemented with Smart Grids, however, the focus has been given to Adaptive Protection techniques. In this review, the previous adaptive protection research works are discussed and organized systematically to help researchers more effectively perform literature reviews and find relevant research works. Furthermore, the important components and draw backs of the adaptive protection is discussed, emphasizing on the gap which the researchers could engage in to improve the adaptive protection techniques.

自适应智能电网保护的现有发展：回顾

摘要 分布式发电（DG）高度集成且需要自愈的未来智能电网旨在以经济和环保的方式提供可靠和优质的电力。未来电网的这一愿景要求在电力系统保护方面采用不同的解决方案。这种需求源于未来智能电网的动态条件，这就是为什么多年来研究和实施了大量保护技术和方法的原因。特别是自适应电力保护技术的研究正在蓬勃发展，因为电力系统非常需要根据系统运行状态和条件实时改变自身的保护设置。该文献调查介绍了智能电网正在实施的许多电力系统保护技术，但重点是自适应保护技术。本次综述对以往的适应性保护研究工作进行了系统的讨论和整理，以帮助研究人员更有效地进行文献综述并找到相关的研究工作。此外，还讨论了自适应保护的重要组成部分和缺点，强调了研究人员可以参与改进自适应保护技术的差距。对以往的适应性保护研究工作进行了系统的讨论和整理，以帮助研究人员更有效地进行文献综述并找到相关的研究工作。此外，还讨论了自适应保护的重要组成部分和缺点，强调了研究人员可以参与改进自适应保护技术的差距。对以往的适应性保护研究工作进行了系统的讨论和整理，以帮助研究人员更有效地进行文献综述并找到相关的研究工作。此外，还讨论了自适应保护的重要组成部分和缺点，强调了研究人员可以参与改进自适应保护技术的差距。
