    ABSTRACT: Electromigration-induced void evolutions in typical upper and lower layer dual-inlaid Copper (Cu) interconnect structures were simulated by applying a phenomenological model resorting to Monte Carlo based simulations, which considers redistribution of heterogeneously nucleated voids and/or pre-existing vacancy clusters at the Copper/dielectric cap interface during electromigration. The results indicate that this model can qualitatively explain the electromigration-induced void evolutions observations in many studies reported by several researchers heretofore. These findings warrant need to re-investigate technologically important electromigration mechanisms by developing rigorous models based on similar concepts.

    ABSTRACT: Electromigration-induced void evolution in various dual-inlaid copper (Cu) interconnect structures was simulated by applying a phenomenological model assisted by Monte Carlo-based simulations, considering the redistribution of heterogeneously nucleated voids and/or pre-existing vacancy clusters at the Cu/dielectric cap interface during electromigration. The results indicate that this model can qualitatively explain the electromigration-induced void evolution observed during experimental in situ secondary-electron microscopy (SEM) investigations as well as in various other reported studies. The electromigration mechanism in Cu interconnect structures and differences in the peculiar electromigration-induced void evolution in various dual-inlaid Cu interconnect structures can be clearly understood based on this model. These findings warrant reinvestigation of technologically important electromigration mechanisms by developing rigorous models based on similar concepts.

    ABSTRACT: Microgrid is a grid which helps to provide the generation in case of Grid failure. Microgrid is a new concept in the arena of green power generation, which is substantially attracting many researchers' interest due to its potential to extend the applications of the distributed generations, especially the renewable energy. Microgrid is a low voltage electrical network with small distributed generators, energy storage devices, controllable loads & protection. A MicroGrid can increase the reliability of energy supplies by disconnecting from the grid in the case of network faults or reduced power quality models for the main microsources/non conventional energy sources including Wind Turbines, Diesel Generator and fuel cells are properly established, in addition to the basic models of the power electronics interfaces being given simultaneously. This project emphasizes modelling & simulation of a Microgrid to account for both the transient and steady-state system characteristics; MATLAB/Simulink is used for the simulation, which can simulate both the steady and dynamic characteristics of the three-phase Microgrid. The result shows that there is an increase in power generation when the microsources/ non conventional energy sources connected within Microgrid which helps in different applications and also in case of grid islanded mode.

    ABSTRACT: Low frequency electromechanical oscillations are inevitable characteristics of power systems and they greatly affect the transmission line transfer capability and power system stability. PSS and FACTS devices can help the damping of power system oscillations. The objective of this paper is to design an advanced PSS and propose a systematic approach for damping controller design for FACTS devices. This paper presents a control scheme, comprehensive analysis and result obtained for the dynamic control of power transmission, damping of oscillations with Unified Power Flow Controller (UPFC) on the basis of theory and computer simulations through MATLAB software. In this paper Unified Power Flow Controller (UPFC) is not designed, but the effect of UPFC on the system under the fault conditions, disturbance, major block outs is being verified.

    ABSTRACT: In this paper a mathematical model is developed for the distribution of voltage and current in the transmission line using distributed state variables. It gives the time domain solution of the terminal voltage and current as well as their line distributions. This is achieved by treating voltage and current distributions as distributed state variables (DSVs) and turning the transmission line equation into an ordinary differential equation. Overall the transmission line is treated like other lumped dynamic components, such as capacitors, inductors, etc using backward differentiation formula for time discretization, the DSV transmission line component is converted to a simple time domain companion model, from which its local truncation error can be derived. As the voltage and current distribution get more complicated with time, a new piecewise exponential with controlled accuracy is invented. A segmentation algorithm is also devised so that the line is dynamically bisected to guarantee that the total piecewise exponential error is a small fraction of the local truncation error. Using this approach, the user can see the line voltage and current at any point and time freely without explicitly segmenting the line before starting the simulation.

    ABSTRACT: The main purpose of this paper is to verify the capability of the gate controlled series capacitor (GCSC) to mitigate subsynchronous resonance (SSR) and electromechanical oscillations that occur when a steam turbine-generator (T-G) is connected to a long transmission line with series compensation. SSR develops the stresses at the coupling of T-G set. This investigation was done based on the IEEE First Benchmark Model. Turn-off pulse generator with zero crossing detectors is used for GCSC. By using turn-off pulse generator capacitive reactance of transmission line can be controlled and hence SSR is mitigated. The Matlab simulink is employed to simulate the effect on stresses of T-G shaft. The simulations results show how the stresses on T-G shaft reduce with the application of GCSC.

    ABSTRACT: Lightning is the most deteriorated and dangerous form of over voltage and it causes hazardous effect on different power equipments, transmission lines, etc and due to it large number of physical and financial losses takes place. In this paper, I did much research on general lightning protection measure that is being taken in order to eliminate or reduce the effect of this natural disaster on different power equipments. Through survey I revealed that by applying one protective measure the effect of lightning stroke on the lines can be reduced to a greater extent. This protective measure is a small needle which when placed vertically on the overhead ground wire reduces the effect. This method can have good effect in lightning protection scheme to mitigate or nullify the over voltages induced on transmission line due to lightning effect. By theoretical analysis and with the help of some literature survey simulated results are obtained using MATLAB.

    ABSTRACT: The main purpose of this paper is to describe a low cost four-switch brushless dc (BLDC) motor drive for commercial application. For effective utilization of the developed system, a direct current controlled PWM scheme is designed. Also the feasibility of the four-switch converter is extended to two-phase BLDC motor drive and the six-switch converter for power factor correction and speed control. The operational principle of the four-switch BLDC motor drive and developed control scheme is theoretically analyzed and the performance is demonstrated by the experimental results.

    ABSTRACT: The main aim of the paper is to analyze the performance of Radial basis function network( RBFN) based SVC on improvement in transient stability and damping of oscillations of the two machine system. This paper presents the comparative performance studies of two different controllers namely: (i) Conventional PI controller, and (ii) Radial basis function network (RBFN). The RBFN model is train by the voltage deviation signal. The coordinated action of proposed SVC controllers with power oscillations damping (POD) control is tested for dynamic performance of the system under various system conditions. The result indicates that the POD in coordination with RBFN based SVC significantly improves the dynamic performance of the system.
