Conventional protection system has relays with fixed setting parameters. It becomes difficult to fulfill the protection requirements in variable operation conditions in general power systems. One of the solution to this problem is the adaptive protection which can vary its parameter settings or the operating characteristics in response to changes in the power system. Using such adaptive protection helps to improve the defects of traditional protection system which can make the protection system better: more reliable, sensitive and rapid. These characteristics and functions can be achieved by properly designing the electrical system and the protection scheme. At the same time ensure that the selected protection can detect and isolate all faulted portions of the electrical system. To guarantee the safety of the task of the power system, the protection equipment ought to be upgraded in like manner. Hence, the energetic structure of power system and their different working conditions need the advancement of adaptive protection techniques. This paper provides the concepts for the general and modern power system protections and highlights the adaptive protection scheme. The overall structure of the adaptive protection is described. The recommendations including software and functions for the future power systems are discussed.
