IET Generation, Transmission &Distribution, Volume 17, Issue 1, Page 161-180, January 2023., 2023 Abstract Superimposed current components contain effective information, which can be employed to enhance the dependability and security of busbar protection relays. This study aims to investigate the use of the slope degree of grey incidence analysis model to design a methodology for busbar protection.

A relaxation scheme to combine Phasor-Mode and Electromagnetic Transients Simulations [PDF]
, 2014 This paper deals with a new scheme for coupling phasor-mode and electromagnetic transients simulations. In each simulation, an iteratively updated linear equivalent is used to represent the effect of the subsystem treated by the other simulation.
