Back to Back Active Power Filter for Multi-Generator Power Architecture with Reduced dc-link Capacitor
… which consists of a delta-delta and a delta-wye phase-shift transformer pair and it effectively mitigates undesirable harmonics from the nonlinear load. In the early 2000s, a shunt type passive front-end for a shipboard power system was proposed. By shunting the two gensets with 30° phase angle …

Performance comparison between Dual-blinder and a Phasor-based Out of Step detection functions using hardware in the loop test
… based on the derivatives of the voltage phase angle difference between the two areas, is evaluated against the Dual-Blinder method using a real-time digital simulator, a protective relay, and a Synchrophasor Vector Processor (SVP). The evaluation shows that the Phasor-Based function …

Circadian rhythm of cortisol and estradiol in healthy women
… It was hypothesized that a cortisol-estradiol phase angle difference (PAD) would exist that would correlate with optimal affect, sleep quality and energy.</p> <p> A small scale, comparative, correlational design was used to test the hypothesis. A sample of twenty-three university women (11 …

Peak-ratio analysis method for enhancement of LOM protection using M class PMUs
… reported in the literature: standard ROCOF, Phase Offset Relay (POR) and Phase Angle Difference (PAD) methods. It is shown that the PRAM technique exhibits comparable performance to the others, and in many cases improves upon their abilities; in particular for systems where the inertia of the …
