This paper is an overview of the sources and nature of various transient over voltages and the problems that may result in a low voltage ac distribution system. Voltage transients may be repeatable transients or random impulses and they have got remarkable effects on semiconductors, electrochemical contacts, insulation etc. Switching parallel loads on the same branch of distribution system as well as lighting are responsible for these transient overvoltages. Low voltage ac mains system should be protected from these transient overvoltages. For ....etc

Transient Stability Analysis On n-bus System
ABSTRACT
• In this project a program for handling the Transient stability of an electrical power system network is developed.
• With the growing stress on today’s power systems, many utilities increasingly face the threat of transient stability problems.
• The project analysis can be divided into two programs:
1. Load Flow Program
2. Transient Stability Program
• It conta ....etc

This article describes the Voltage swell and overvoltage compensation problems in a diode-bridge rectifier supported transformerless-coupled
dynamic voltage restorer (DVR). applying conventional in-phase or phase-invariant boosting method in case of condition of swell or overvoltage, may cause a a rapid rise in dc-link voltage which may ultimately lead to the damage of the storage capacitors and switching devices, and increase the switching loss. The minimum energy injection scheme is unable to solve these problems. Here, a novel unidirectio ....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

Overvoltage protection concept for DC railway systems



ABSTRACT

Overvoltages in electrical networks result from the effects of lightning strokes and switching actions and cannot be avoided. Furthermore, the power supply of electrical railways is endangered by direct or nearby lightning. A new device, combining protection against overvoltages and touch voltages and protection of people is introduced. Protection concepts for DC railway systems are introduced, cons ....etc
