islanding detection methods for microgrids
امروزه استفاده از منابع انرژی پراکنده کاربرد وسیعی یافته است . اگر چه این منابع بسیاری از مشکلات شبکه را حل می کنند اما زیاد شدن آنها مسائل فراوانی برای سیستم قدرت به همراه دارد . استفاده از میکروشبکه راه حلی است که علاوه بر استفاده از مزایای منابع انرژی پراکنده برخی از مشکلات ایجاد شده توسط آنها را نیز منتفی می کند . همچنین میکروشبکه ها کیفیت برق و قابلیت اطمینان تامین انرژی مشترکان را افزایش ...
15 صفحه اولDetection of a Curved Hard X-ray Spectrum
A report is presented on Suzaku observations of the ultra-luminous X-ray source X-1 in the starburst galaxy M82, made three time in 2005 October for an exposure of ∼ 30 ks each. The XIS signals from a region of radius 3 around the nucleus defined a 2–10 keV flux of 2.1× 10 erg s cm attributable to point sources. The 3.2–10 keV spectrum was slightly more convex than a power-law with a photon ind...
متن کاملThe Hard Truth about Some “Soft” X-ray Transients
We have accumulated multiwavelength lightcurves for eight black hole X-ray binaries which have been observed to enter a supposed “soft X-ray transient” outburst, but which in fact remained in the low/hard state throughout the outburst. Comparison of the lightcurve morphologies, spectral behaviour, properties of the QPOs and the radio jet provides the first study of such objects as a subclass of...
متن کاملNew Perspectives of X-ray Techniques for Explosive Detection Based on CdTe/CdZnTe Spectrometric Detectors
Conventional explosive detection systems (EDS) based on X-ray technologies are using dual-energy radiography; they provide only a crude material characterization. Recently emerged semiconductors based X-ray detectors offer new capabilities in energy discrimination. This study is aiming at evaluating their interest for EDS. LETI-LDET laboratory has developed several pixellated CdTe/CZT detectors...
متن کاملDirect Measurement of Mammographic X-Ray Spectra with a Digital CdTe Detection System
In this work we present a detection system, based on a CdTe detector and an innovative digital pulse processing (DPP) system, for high-rate X-ray spectroscopy in mammography (1-30 keV). The DPP system performs a height and shape analysis of the detector pulses, sampled and digitized by a 14-bit, 100 MHz ADC. We show the results of the characterization of the detection system both at low and hig...
