Blackouts in power grids usually result from cascading faults. The key importance of the electric power grid for society encourages further research into maintaining the reliability of the energy system and developing new methods to manage the risks of cascading blackouts. Appropriate software tools are required to better analyse, understand, and evaluate the consequences of cascading failures. This article presents MATCASC, an open-source MATLAB-based tool for analysing cascading faults in electrical networks. Cascade effects due to line overh ....etc

Voltage Stability Improvement using Static Var Compensator in Power Systems

Abstract This paper investigates the effects of Static Var Compensator (SVC) on voltage stability of a power system. The functional structure for SVC built with a Thyristor Controlled Reactor (TCR) and its model are described. The model is based on representing the controller as variable impedance that changes with the firing angle of the TCR. A Power System Computer Aided Design /Electromagnetic Transients including DC (PSCAD/EMTDC) is used to ....etc

Steady-state bumpless transfer under controller uncertainty using the state/output feedback topology
Linear quadratic (LQ) bumpless transfer design gives a very convenient and straightforward computational procedure for the steady-state bumpless transfer operator synthesis. It cannot, however provide convergence of the output of the offline controller to that of the online controller in many industrial applications thereby producing bumps in the plant output in the wake of controller transfer. the applications in question are characteri ....etc

Feedback linearization method for improvement of power systems transient stability
MINI PROJECT

ABSTRACT
Feedback linearization is a common approach used in controlling nonlinear systems. The approach involves coming up with a transformation of the nonlinear system into an equivalent linear system through a change of variables and a suitable control input. It is done by algebraically transforming non-linear system dynamics into a linear one so that linear control techniques can be applied. The canonical form and the general form of ....etc

MATLAB/Simulink-based transient stability
analysis of a multimachine power system



Abstract

Simulink is advanced software by MathWorks Inc., which is increasingly being used as a
basic building block in many areas of research. As such, it also holds great potential in the area of
power system simulation. In this paper, we have taken a multi-machine power system example to
demonstrate the features and scope of a Simulink-based model for transient stability analysis. A selfsufficient
model has been giv ....etc

The stability of power systems has been and continues to be a major concern in the operation of the system. Modern electrical power systems have grown to great complexity due to increased interconnections, the installation of large generation units and high voltage connection lines, etc. Transient stability is the ability of the power system to maintain synchronism when subjected to a severe transient disturbance, such as failure in transmission facilities, sudden loss of generation or loss of a large load. The system response to such disturban ....etc

Abstract
In this paper steady-state modeling of Static VAR Compensator (SVC) and Thyristor Controlled Series Compensator (TCSC) for power flow studies has been represented and discussed in details. Firing angle model for SVC was proposed to control the voltage at which it is connected. In same manner firing angle model for TCSC is used to control active power flow of the line to which TCSC is installed. The proposed models take firing angle as state variable in power flow formulation. To validate the effectiveness of the proposed models ....etc

We analyze the feedback loop in Tele-Graffiti, a cameraprojectorbased remote sketching system which we recentlydeveloped. We derive the gain through the feedback loopand the final images that will be viewed by the users of thesystem. We then derive the optimal gain as the gain thatresults in the final viewed images being as close as possibleto the sum of the images actually drawn on the paper. Wealso propose a way of using the projector to compensate forinsufficient ambient light and describe how our analysis isaffected by: (1) automatic gain ....etc
