Introduction
In order to increase the switching frequency while maintaining acceptable efficiency, several soft switching techniques have been developed . Most of these resonant techniques increase the semiconductor current and/or voltage stress, leading to larger devices and ncreased
conduction losses due to greater circulating current. A new class of converters has been developed , however, that allow an increase in switching frequency without the associated increase in s ....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

POWER SYSTEM STABILITY: NEW OPPORTUNITIES FOR CONTROL


I. Introduction
The power system networks in North America and Europe are the largest man-made
interconnected systems in the world. The Eastern Interconnection in North America that
stretches from the East Coast to almost the Rocky Mountains is the largest in terms of
geographic area covered, total installed generation capacity and total miles of transmission lines.
Moreover, all the rotating generators in one network rotate synchronously producing a ....etc

hello
i need examples for using the extended equal area criteria for transient stability assessment for multi-machine powersystem
i need examples to determine critical clearing time for fault occur in power system to remain in stable case.

How to understand the Simulink messages on the ACLine parameters presented as following strings:
Resistances
Inductances ?
Are these r and x specific parameters (per unit length) or they relate to the full length of the line?
For an inductance do the values mean inductivity (L in henry) or
reactance (x = wL in Ohms) ?
The values at the end of strings are they in pu or something else ?

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
