ABSTRACT The main focus of this paper is to control the active power supplied by distributed generation (DG) system while compensating harmonics and reactive currents caused by the nonlinear loads using shunt active power filter (APF). The APF control is based on load currents sensing for reference current estimation in a-b-c reference frame. In order to get the grid currents sinusoidal and in-...

English for Specific Purposes (ESP), as the bridge curriculum between an ordinary English (EGP) and the English, helps meet the actual needs of students, so it is necessary to introduce ESP into College English teaching. In this paper, based on the needs analysis theory, it studies demand conditions of English for Specific Purposes for non-English majors through questionnaires. The survey finds...

This review describes the history of discovery of violation of spatial parity P, charge conjugation parity C, combined parity CP. The hypothesis of existence of mirror particles was called upon by its authors to restore the symmetry between left and right. The review presents the emergence and evolution of the concepts " mirror particles " and " mirror matter ". It could serve as a concise guid...

The current meta-analysis of the selection validity of assessment centres aims to update an earlier meta-analysis of assessment centre validity. To this end, we retrieved 26 studies and 27 validity coefficients (N1⁄4 5850) relating the Overall Assessment Rating (OAR) to supervisory performance ratings. The current study obtained a corrected correlation of .28 between the OAR and supervisory job...

this paper presents a new control method for a three-phase four-wire unified power quality conditioner (upqc) to deal with the problems of power quality under distortional and unbalanced load conditions. the proposed control approach is the combination of instantaneous power theory and synchronous reference frame (srf) theory which is optimized by using a self-tuning filter (stf) and without us...

In this paper, a simple control scheme of single-phase shunt active power filter for current harmonics and reactive power compensation of linear and non-linear loads, is proposed. Simplicity of the proposed control scheme is based on uncomplicated reference source current generation and fuzzy logic based dc bus voltage regulation methods. Thus, complex computations are not needed. To indicate r...

Rating one’s own personality traits is a common self-referential information processing task. The current paper examined the mechanism underlying this sort of trait-rating task by using a PC cursor tracing technique (Shiina, 2011a, b). The target phenomenon of interest was the inverted-U effect observed in trait ratings. The PC cursor tracing technique analyzed response times, tangential veloci...

CNFET is generally considered to be one of the most appealing next generation transistors because of its high current carrying capacity and ballistic transport property. This paper investigates the performance analysis of Dual-X Current Conveyor with the CNFET technology, by varying the CNT diameter at 32nm technology node. Current Bandwidth, Input and Output Port resistances of the device alon...

Remarkable progress in distributed power generation invigorated research into DC microgrids using a controllable DC–DC converter contingent to the functionalities therein. The study explores circulating current issue parallel-connected and its associated current-sharing capability. Despite, conventional droop being promising solution with less control complexity, sharing is achieved at an expen...
