摘要: Faults and power swings are chiefly responsible for most of the grid disturbances. Power swing often causes misfiring relays leading to blackout. This paper approached by deriving a mathematical expression which would be able track locus impedance in time domain. can used tuning relays. The derived was compared with generated using matlab/simulink model results were analyzed R-X plane R-X-t space. Results indicated that expressions agreement simulated swing. Usage dynamic plots (R-X-t space) gave better insight on instantaneous movement both resistance reactance.
