An experimental evaluation of a power differential relay is conducted and the results are described. The experimental setup consists of a generator connected to the network via a transmission line protected by the power deferential relay. The relay input signals, fundamental active and reactive powers, are locally computed from the complex product of the current and voltage phasors at each end on...

In this paper different acquisition methods were presented. Evaluation of a serial and parallel-search DS-SS, single and double dwell time acquisition system is given with and without incorporating an intentional jamming. The mean acquisition time is considered to be the performance measure of the receiver using a certain PN codes as spreading codes. The effects of probability of detection (PD), probability...

This paper describes the details of a Simulink-based dynamic testing of the power differential relay. Power differential relay has been simulated and tested for transmission lines as a MATLAB/SIMULINK model with the use of the Power System Blockset. The developed modeling facilitates testing the dynamic behavior of the power differential relay during fast system transients. Different outputs have...
