The grid-connected or standalone Pv central inverter architecture is comprised of several Pv modules which are connected in different ways to form the Pv *** power generation capability of the Pv array is primarily affected by partial shading conditions(PsC).Due to PsCs,the power output of the Pv array is dramatically reduced,and mismatching losses are induced in the Pv *** on the extent of these problems,multiple peaks also appear in the power-voltage(P-v)curve,which makes it very difficult to track the global maximum power point(GMPP).The main objective of this research paper is to model and simulate the series(s),series-parallel(sP),bridge-link(BL),honey-comb(HC),total-cross-tied(TCT)and proposed triple-tied(TT)solar Pv array configurations under various partial shading *** performance of all Pv configurations is evaluated under a uniform approach,considering eight different shading *** performance of the considered Pv configurations is analyzed in terms of their mismatching power losses,fill factors,efficiency,global maximum power points(GMPPs),local maximum power points(LMPPs),voltages and currents at GMPPs,open circuit voltage and short circuit *** above-mentioned Pv configurations are modeled and simulated in a Matlab/simulink environment by considering the KC-200GT module parameters.

The technological,economic,and environmental benefits of photovoltaic(Pv.s.stems have led to their wide-spread adoption in recent years as a source of electricity ***,precisely identifying a Pv.s.stem’s maximum power point(MPP)under normal and shaded weather conditions is crucial to conserving the maximum generated *** of the biggest concerns with a Pv.s.stem is the existence of partial shading,which produces multiple peaks in the P–v characteristic *** these circumstances,classical maximum power point tracking(MPPT)approaches are prone to getting stuck on local peaks and failing to follow the global maximum power point(GMPP).To overcome such obstacles,a new Lyapunov-based Robust Model Reference Adaptive Controller(LRMRAC)is designed and implemented to reach GMPP rapidly and *** proposed controller also achiev.s.MPP accurately under slow,abrupt and rapid changes in radiation,temperature and load *** and OPAL-RT real-time simulators in various scenarios are performed to verify the superiority of the proposed approach over the other state-of-the-art methods,i.e.,ANFIs,INC,vsPO,and P&*** and GMPP are accomplished in less than 3.8 ms and 10 ms,*** on the results presented,the LRMRAC controller appears to be a promising technique for MPPT in a Pv.s.stem.

Numerical and analytical inv.s.igations of thermosolutal instability in rotating Rivlin-Ericksen fluid in porous medium with Hall current

引用

Applied Mathematics and Mechanics(English Edition) 2013年第4期34卷 501-522页

作者： s.kumar v.s.ARMA K.KIsHOR Department of Mathematics Government College Department of Mathematics Himachal Pradesh University Department of Mathematics Government Senior Secondary School

Numerical and analytical inv.s.igations of the thermosolutal instability in a v.s.oelastic Rivlin-Ericksen fluid are carried out in the presence of a uniform vertical magnetic field to include the Hall current with a uniform angular velocity in a porous medium. For stationary convection, the stable solute gradient parameter and the rota- tion have stabilizing effects on the system, whereas the magnetic field and the medium permeability have stabilizing or destabilizing effects on the system under certain condi- tions. The Hall current in the presence of rotation has stabilizing effects for sufficiently large Taylor numbers, whereas in the absence of rotation, the Hall current always has destabilizing effects. These effects have also been shown graphically. The v.s.oelastic effects disappear for stationary convection. The stable solute parameter, the rotation, the medium permeability, the magnetic field parameter, the Hall current, and the v.s. coelasticity introduce oscillatory modes into the system, which are non-existent in their absence. The sufficient conditions for the non-existence of overstability are also obtained.

A Comparative study on the Milling speed for the synthesis of Nano-structured Al 6063 Alloy Powder by Mechanical Alloying

引用

Journal of Minerals and Materials Characterization and Engineering 2011年第6期10卷 507-515页

作者： Hafeez Ahamed v. senthil kumar Department of Production Engineering National Institute of Technology Thiruchirappalli-620015 India.

The present article reports on characterization studies performed on amorphized nanostructured Al 6063 alloy powder synthesized by mechanical alloying (MA). The as-milled powder was characterized by X-ray diffraction (XRD) for inv.s.igating the development of crystallite nature and determining the different phases of the materials present, scanning electron microscope (sEM) was used for in depth morphological study and High Resolution-transmission electron microscope (HR-TEM) was employed to ensure the development of a nano-structured nature of the Al 6063 matrix. In the present work alloyed powder was milled for 20 h and 40 h at 300 rpm;and 20 h at 700 rpm in a hardened stainless steel medium. Using Williamson-Hall equation;crystallite size, lattice strain and lattice parameter of Al 6063 nanostructure alloy powder was estimated with broadening of XRD peaks. XRD results showed that the crystallite size of Al 6063 alloy powder reached 32 and 53 nm after 20 h at 700 rpm and 40 h at 300 rpm respectively.
