Methods of calculation of reliability of protective relay devices
Proceedings KORUS 2000. The 4th Korea-Russia International Symposium On Science and Technology, 2002A technique which accounts for the hardware reliability of devices and systems of protective relay of power systems is described. The model developed by the authors to account for reliability takes into account the work of functional and test diagnostic devices, and also checks of the serviceability of devices of protection after their refusal to ...

The impact of FACTS device on digital multifunctional protective relays
IEEE/PES Transmission and Distribution Conference and Exhibition, 2003In this paper, the results of the application of multifunctional relays for the protection of compensated lines with FACTS devices is presented. The impact of different FACTS devices on the protective relays behavior is investigated. Since the distance relay is of great concern in transmission lines, the role of the applied protective algorithm in the ...

A custom power protection device controlled by a neural network relay
2000 Power Engineering Society Summer Meeting (Cat. No.00CH37134), 2002Voltage dips are becoming an increasing concern to many industrial and commercial customers, due to the problems they cause on several types of equipment. In industrial plants equipped with private generating systems, in case of a fault in the supply feeder, the protection device will disconnect the customer plant from the utility system, preserving ...
