Mathematical model on magneto-hydrodynamic dispersion in a porous medium under the influence of bulk chemical reaction

Abstract: The mathematical model of hydrodynamic dispersion through a porous medium is developed in the presence of transversely applied magnetic fields and axial harmonic pressure gradient. The solute introduce into the flow is experienced a first-order chemical reaction with flowing liquid. The dispersion coefficient is numerically determined using Aris’s moment equation of solute concentration. The numerical technique employed here is a finite difference implicit scheme. Dispersion coefficient behavior with Darcy number, Hartmann number and bulk flow reaction parameter is investigated. This study highlighted that the dependency of Hartmann number and Darcy number on dispersion shows different natures in different ranges of these parameters.

A Study on Software Risk Management Strategies and Mapping with SDLC

Abstract: In recent years, despite several risk management models proposed by different researchers, software projects still have a high degree of failures. Improper risk assessment during software development was the major reason behind these unsuccessful projects as risk analysis was done on overall projects. This work attempts in identifying key risk factors and risk types for each of the development phases of SDLC, which would help in identifying the risks at a much early stage of development.

Active and reactive power control of a grid connected speed sensor less DFIG based wind energy conversion system

Abstract: This paper presents the performance study of a speed sensor-less control of grid connected DFIG based variable speed Wind Energy Conversion System (WECS). A new phase locked loop (PLL) based slip speed estimator using rotor current is proposed for speed sensor-less stator field oriented vector control operation of rotor side converter (RSC) to ensure decoupled control of stator active and reactive power while maximizing the power generation at unity power factor under varying wind speed. The estimated slip speed is used for back emf compensation of rotor current controllers. Simulation has been carried out in MATLAB/Simulink environment and results show satisfactory operation of the proposed speed sensor-less DFIG based variable speed WECS.

Voltage stability assessment in radial distribution system by line stability indicator (LSI) and its improvement using SVC

Abstract: Load demands on distribution system is growing rapidly. So, the distribution system is operating nearer to the stability boundary. A stability index named line stability indicator (LSI) is developed in this paper for voltage stability analysis of radial distribution system. The applicability of the indicator is tested on a standard (IEEE) 33-bus Radial Distribution System. To find the value of proposed indicator for different lines of the system under consideration MATLAB code is used. This indicator is able to find the weak lines of the system. By using FACTS device at the receiving end side of the weak line the voltage level of buses of the system can be improved. Results indicate that installation of FACTS device at the appropriate bus will make the whole system more stable in respect of voltage.
