Omar H. Abdalla
The paper presents simulation studies of installing a number of diesel-engine driven generating units at selected locations in the main transmission system of Oman. A total of 300MW generator units are proposed on a temporary basis to aid in meeting the peak demand in summer 2011. A digital model is developed to simulate the system including central power plants, transmission system, loads and the proposed Distributed Generation (DG). The model includes representation of governor and excitation systems. The simulation studies are performed by using the DIgSILENT PowerFacrory software package. The objective of the studies is to demonstrate effects of the …

Dr. Et-touhami Es-sebbar
Saturn's largest satellite, Titan, is the only one in the Solar System known to have a thick N2/CH4, planet like atmosphere. The dissociation of these principal components and the recombination of the products make this atmosphere to be rich in organic compounds of high interest for astrobiology. Solar and stellar occultations observed by the Ultraviolet Imaging Spectrograph (UVIS) on board the Cassini spacecraft can be used to characterize the composition of Titan’s upper atmosphere (400 – 1400 km). The results depend strongly on the knowledge of the molecular absorption cross sections of the atmospheric constituents (Ferradaz et al. 2009). This …
Experimental Study Of Shoot-Through Control Methods For Z-Source Inverter, Omar Ellabban, Joeri Van Mierlo, Philippe Lataire
Experimental Study Of Shoot-Through Control Methods For Z-Source Inverter, Omar Ellabban, Joeri Van Mierlo, Philippe Lataire
Omar Ellabban
This paper presents a simulation and experimental comparative analysis of the Z-source inverter (ZSI) with four different shoot-through (ST) control methods, namely: the simple boost control, the maximum boost control, the maximum constant boost control and the modified space vector modulation boost control methods. A review of these methods is presented with a summary of all expressions. A prototype of a 30 kW ZSI is designed and implemented. The eZdsp™ F2808 evaluation board is used for the realization of the shoot-through control methods and the real time workshop (RTW) is used for automatic code generation. The paper compares between the …

Dr. Et-touhami Es-sebbar
Low-temperature hydrogen plasmas are widely used as continuous vacuum ultraviolet irradiation sources in photochemical studies and, in particular, in laboratory simulations of planetary atmospheres. One of the most challenging objectives of such experiments is to retrieve accurate quantitative laboratory data allowing a reliable comparison with theoretical and/or observational ones. This task can only be achieved when the irradiation source delivers a well characterised radiation in terms of flux and wavelength dependency. As an example, we will present a study, developed in the frame of a program dedicated to simulations of Titan’s atmosphere, on methane photolysis at Lyman alpha (121.6 nm). …

A Dsp Based Dual Loop Digital Controller Design And Implementation Of A High Power Boost Converter For Hybrid Electric Vehicles Applications, Omar Ellabban, Joeri Van Mierlo, Philippe Lataire
A Dsp Based Dual Loop Digital Controller Design And Implementation Of A High Power Boost Converter For Hybrid Electric Vehicles Applications, Omar Ellabban, Joeri Van Mierlo, Philippe Lataire
Omar Ellabban
This paper presents a DSP based direct digital control design and implementation for a high power boost converter. A single loop and dual loop voltage control are digitally implemented and compared. The real time workshop (RTW) is used for automatic real-time code generation. Experimental results of a 20 kW boost converter based on the TMS320F2808 DSP during reference voltage changes, input voltage changes, and load disturbances are presented. The results show that the dual loop control achieves better steady state and transient performance than the single loop control. In addition, the experimental results validate the effectiveness of using the RTW …

Dr. Adel A. Elbaset
Dealing with power distribution system became one of the most important arts in the field of power system, especially in the rapid increase of the distributed generation (DG) penetration to the distribution level which is a vital and important part of the entire power system. In this paper, a very special power distribution system with a unique deployment of distributed generation, such as, photovoltaic and wind generation has been studied. Energy storage system is utilized to play the main role to control the system’s power quality and the system frequency, as load following operation (LFO) and automatic generation control (AGC), …

The paper presents steady-state and transient studies to assess the impact of a 200MW Concentrated Solar Power (CSP) plant connection on the Main Interconnected Transmission System (MITS) of Oman. The CSP plant consists mainly of a solar field with parabolic trough collectors, two thermal storage tanks, heat exchangers, piping systems, steam turbine, and electric generator. Two proposed locations are considered to connect the CSP plant to MITS: Manah and Adam 132/33kV grid stations in Al-Dakhiliah region. The transmission grid model of 2015 has been updated to include the simulation of the proposed 200MW CSP at either Manah or Adam. The …
