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

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

ENHANCED PERFORMANCE OF A DOUBLY FED
WIND-POWER INDUCTION GENERATOR AT WIND-
RANGE BOUNDARIES
ABSTRACT
The doubly fed induction generator (DFIG) is one of the largest generators used
with MW-class wind turbines. This paper focuses on the weak performance areas
of grid-connected DFIG-based wind turbines. Basically, the DFIG performance at
low wind speeds, close to the cut in speed, and around the full rating operation (in
the vicinity of rated wind speed) is investigated. For low wind speed region, the

Control of variable speed wind turbines equipped with synchronous or doubly fed induction generators supplying islanded power systems
Abstract:
A control method for variable speed wind turbines (VSWTs) supplying islanded parts of electricalnetworks is presented. Active power/frequency and reactive power/voltage droops are applied in order todetermine the active, reactive power production, thus downscaling to the VSWTs the conventional controlconcepts of the power plants. Two types of VSWTs comprising doubly fed induction gene ....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
