A fault identification method using LSTM for a closed-loop distribution system protective relay

International Journal of Electrical Power and Energy Systems, 2023
We use machine-learning to train communication-free protective relays of a closed-loop distribution system. The proposed algorithm in the protective relays affords primary protection against electrical faults and classifies the fault types. We propose to

Rough-Set-and-Genetic-Algorithm based data mining and Rule Quality Measure to hypothesize distance protective relay operation characteristics from relay event report [PDF]

International Journal of Electrical Power and Energy Systems, 2011
Protective relay performance analysis is only feasible by first formulating the hypothesis of expected relay operations beforehand. Traditionally, the process involved in discovering the relay operation characteristics is bogged down by the issues of ...

Practical EMV Relay Protection

2022 IEEE Symposium on Security and Privacy (SP), 2022
Relay attackers can forward messages between a contactless EMV bank card and a shop reader, making it possible to wirelessly pickpocket money. To protect against this, Apple Pay requires a user's fingerprint or Face ID to authorise payments, while Mastercard and Visa have proposed protocols to stop such relay attacks.

Electronic Protective Relays

Transactions of the American Institute of Electrical Engineers, 1948
Although electromagnetic protective relays are adequate for present requirements, the ever-increasing demand for higher speeds and greater accuracy and dependability seems likely to exceed the capabilities of relays now available. However, the trend toward electronic control circuits in other branches of electrical engineering, coupled with the recent ...

Simplicity in protective relaying

Electrical Engineering, 1946
SIMPLICITY is of paramount importance when designing and laying out protective relay circuits. These circuits are called upon to operate so infrequently that they should be more reliable than the apparatus or lines they protect. Certain limiting conditions and requirements requested by circuit designers generally cause false tripping and make the ...

Relay Protective Systems

Transactions of the American Institute of Electrical Engineers, 1912
Reviewing American practise in the use of relay protective devices for electrical generating, transmission and distributing systems, there appears to have been no material change in the construction or commercial application of this class of apparatus in a considerable period of years.
