Proper location of DGs in power systems is important for obtaining their maximum potential benefits. This paper deals with DG for minimizing active power loss and D-statcom for reactive power loss minimization is considered. The proper siting of DG and D-statcom is a recently developed combination with the aim of reducing line loss in a radial distribution system. Loss Sensitivity Factor (LSF) ...

purpose: to evaluate the role of active uveitis on refractive errors changes. methods: a cohort single group study was conducted on patients with acute or recurrent uveitis. cyclorefraction was performed in both phases of active and quiescent. sphere, cylinder and sphere equivalent power were compared in active and quiescent phases and analyzed statistically. results: sixty-six patients (eighty...

The doubly fed induction generator (DFIG) is one of the most popular technologies used in wind power systems. With the growing use of DFIGs and increasing power system dependence on them in recent years, protecting of these generators against internal faults is more considered. Loss of excitation (LOE) event is among the most frequent failures in electric generators. However, LOE detection stud...

This paper proposes a new method of sliding mode base controller for shunt active power filter to compensate the harmonic currents of a load. In this controller there isn't any need to PI DC voltage controller to regulate the DC capacitor voltage of shunt active power filter. In this method, first the reference currents of shunt active power filter that should be tracked to reduce or eliminate ...

We consider the asymmetric active coupler (AAC) consisting of two coupled dissimilar waveguides with gain and loss. We show that under generic conditions, not restricted by parity-time symmetry, there exist finite-power, constant-intensity nonlinear supermodes (NS), resulting from the balance between gain, loss, nonlinearity, coupling and dissimilarity. The system is shown to possess non-recipr...

The reverse link in-cell and other-cell interference in power controlled cellular CDMA networks determine the reverse link capacity, and thus to a large extent the overall network capacity. A common modeling assumption is that a mobile is power controlled by a sector belonging to a set closest to it (minimum reverse link path-loss sense). However, in an actual IS-95-based system the mobile tran...
