2014 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC), 2014
In this paper, common DC-fault detection methods have been reviewed. Effects of two line-to-line and line-to-ground fault types from various fault locations to operation of the DC system are presented. In addition, operation principle, strong and weak points of four main types of protection devices (including fuses, no-fuse circuit breakers, power ...

Intelligent method for protection coordination
2004 IEEE International Conference on Electric Utility Deregulation, Restructuring and Power Technologies. Proceedings, 2004This paper presents the application of artificial intelligence in protection coordination. It can substantially improve the coordination of protection relay operations. The relay settings and coordination requirements are formulated into a set of constraint equations and an objective function is developed to manage the relay settings by the time ...

Coordinating overcurrent protection devices
IEEE Computer Applications in Power, 1996Distribution, substation, and plant engineers can benefit from using an overcurrent protection program in commercial, industrial, and utility applications to aid in clearing temporary faults and isolating permanent faults. In the time it normally takes to check one coordination scheme manually, dozens of alternatives can be evaluated using a graphics ...
