active filters have proven to be more effective than passive techniques to improve power quality and to solve harmonic and power factor problems due to nonlinear loads. this paper proposes a control scheme based on the instantaneous active and reactive power. the inverter of this active filter is a three-phase, two-level converter. space vector technique is used as modulators and pattern genera...

We present on-chip oscillator arrays synchronized by random noises, aiming at skew-free clock distribution on synchronous digital systems. Nakao et al. recently reported that independent neural oscillators can be synchronized by applying temporal random impulses to the oscillators [1], [2]. We regard neural oscillators as independent clock sources on LSIs; i.e., clock sources are distributed on...

A protection scheme is proposed using alienation method derived from coherence model which a backup for the differential overcurrent of synchronous generators. This realized by computational technique based on coefficients estimated generator voltage and current signals considered to be mounted beside main system, operates in cases that unable detect internal faults. novel algorithm adjusting s...

To improve the primary frequency response in future low-inertia hybrid power system a fuzzylogic based frequency controller (FFC) for wind farms augmented with energy storage systems(wind-storage system) and intelligent PV farms for the frequency stabilization is proposed inthis paper. Using system frequency deviations the proposed controller provides bidirectionalreal p...

this paper represents the performance of a squirrel-cage high temperature superconducting induction/ synchronous motor (hts-ism) based on nonlinear electrical equivalent circuit. the structure of the hts-ism is the same as that of the squirrel-cage type induction machine, and the secondary windings are fabricated by the use of the hts wires. it has already been shown that based on the experimen...
