Abstract: In this study, the effect of fuel injection discharge curve and injection pressure simultaneously for upgrading power of heavy duty diesel engine by simulation of combustion process in AVL-Fire software are discussed. Hence, the fuel injection discharge curve was changed from semi-triangular to rectangular which is usual in common rail fuel injection system. Injection pressure with r...

In this article, the power generation of a concentrated space solar station (SSPS) is enhanced by current-injected total-cross-tied (TCT-CI) photovoltaic (PV) array. First, mathematical model TCT-CI–connected PV array established. Second, arrays with several common topologies and TCT-CI topology are simulated analyzed using MATLAB/Simulink. At last, comparative experiments conducted for TCT und...

Grid impedance estimation is used in many power system applications such as grid connected renewable energy systems and power quality analysis of smart grids. The grid impedance estimation techniques based on signal injection uses Ohm’s law for the estimation. In these methods, one or several signal(s) is (are) injected to Point of Common Coupling (PCC). Then the current through and voltage of ...

In this paper, an adaptive control strategy is proposed for the inverters of renewable energy source (RES) to simultaneously control the load voltage, grid current and the amount of instantaneous injected power to the grid in the presence of grid voltage distortions and nonlinearity of load current. In the proposed control strategy, the power quality of the local load can be settled based on th...

– Our interest goes to the power injected in a heated granular gas and to the possibility to interpret it in terms of entropy flow. We numerically determine the distribution of the injected power by means of Monte-Carlo simulations. Then, we provide a kinetic theory approach to the computation of such a distribution function. Finally, after showing why the injected power does not satisfy a Fluc...

In this letter, the power range to be covered with maximized efficiency by a two-way outphasing amplifier (PA) is significantly extended, thanks proposed architecture injection of an external signal. Using reactively terminated quadrature hybrid coupler (QHC) as nonisolating combiner, Chireix topology transformed into slight variation in load-modulated balanced (LMBA) when auxiliary branch acti...
