Voltage Sags and the Response of a Synchronous
Distributed Generator: A Case Study

Edward R. (Randy) Collins, Senior Member, IEE, and Jian Jiang, Student Member, IEE


Abstract

The dynamic behavior of a synchronous distributed
generator connected to a distribution system during fault conditions
is studied. A fault on an actual system was found to have
a sag that was extended after the fault was cleared. It is shown
that the combination of the generator and the load on the system
contributes to th ....etc

REGULATED POWER SUPPLY
1.1 Types of Power Supply
There are many types of power supply. Most are designed to convert high voltage AC mains electricity to a suitable low voltage supply for electronic circuits and other devices. A power supply can by broken down into a series of blocks, each of which performs a particular function.
For example a 5V regulated supply:

Each of the blocks is described in more detail:
Transformer- steps down high voltage AC mains ....etc

mini projet report
Voltage source inverters (VSI) have been widely used in uninterruptible power supplies, unified power flow controllers or unified power quality conditioners, and distributed generation systems (DGS). VSIs are inherently efficient, compact, and economical devices used to control power flow and provide quality supply. VSIs can be classified as voltage-controlled VSIs (VCVSIs) and current-controlled VSIs (CCVSIs), depending on their control mechanism. In this paper, a detailed comparison of VCVSIs and CCVSIs for DG ....etc

EFFECTS OF VOLTAGE SAGS, SWELL AND OTHER DISTURBANCES ON
ELECTRICAL EQUIPMENT AND THEIR ECONOMIC IMPLICATIONS



ABSTRACT

Poor power quality has come to stay in most parts of the
world. In most part of Africa, especially in Nigeria, it is
almost normal not to have good clean power free from
disturbances. If power equipment and loads could talk or
express feelings, I am sure they would have made a big
protest against the great injustices imposed on them. A
survey was carried out amongst 15 multi-nation ....etc

Abstract:
Partial discharge (P.D.) in micro cavities in the insulation of H.V. power cables drastically affect the performance, the field distribution and hence the rating of these cables. It is well known that, P.D. deteriorates power cables and lead to its complete failure. This has adverse effects on the reliability and maintainability of power supply, which affects directly the production of industrial factories. In this work a study and investigation of the effect of partial discharges in caviti ....etc

single phase ac voltage regulators using triac and diac combination for r load and rl load

Abstract

The DIode AC switch, or Diac for short, is another solid state, three-layer, two-junction semiconductor device but unlike the transistor the Diac has no base connection making it a two terminal device, labelled A1 and A2. Diac s have no control or amplification but act much like a bidirectional switching diode as they can conduct current from either polarity of a suitable AC voltage supply.In our tutorial about SCR s and Triacs, we saw that i ....etc
