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

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



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
con ....etc

Synchronous generator
One of the most important types of electrical rotating machines is the synchronous generator, this machine is capable of converting mechanical energy into electricity when operated as a generator and power mechanics when operated as a motor.
Synchronous generators are used in the majority of hydroelectric and thermoelectric plants.
The name Sync is because of this machine to operate with a constant speed synchronized with the frequency of the alternating voltage applied to the terminals of t ....etc

ADAPTIVE AND NON-LINEAR EXCITATION CONTROL OF SYNCHRONOUS GENERATOR‟S STABILITY THROUGH NEURAL NETWORK

ABSTRACT
Adaptive and non linear Excitation control of synchronous generator‟s stability through Neural Network Control equipment of synchronous generators such as automatic voltage regulators, speed governors and power system stabilizers have been developed to maintain stability and to improve damping of the power systems. When an operating condition changes greatly, however, such controllers may become less effective b ....etc

Abstract:
Voltage sag are the major source of power quality related problems. Dynamic Voltage restorers (DVR) are used to protect sensitive loads from the effects of voltage sag on the distribution feeder. It injects voltage in series with the system voltage to compensate the sag. This paper presents a power system operation with PI controller approach. Total Harmonics Distortion (THD) is calculated for the system in absence of compensation scheme next THD is evaluated when DV ....etc
