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

The synchronous voltage source is implemented by a multi-pulse inverter using gate turnoff (GTO) thyristors . It is capable of generating internally the reactive power necessary for network compensation, and is also able to interface with an appropriate energy storage device to negotiate real power exchange with the ac system. The paper develops a of power flow control using solid - state synchronous voltage sources for shunt compensation, series compensation , and phase angle control .

It also describes the unified powerflow contro ....etc

The Synchronous optical network, commonly known as SONET, is a standard for communicating digital information using lasers or light emitting diodes (LEDs) over optical fiber as defined by GR-253-CORE from Telcordia. It was developed to replace the PDH system for transporting large amounts of telephone and data traffic and to allow for interoperability between equipment from different vendors.
The more recent Synchronous Digital Hierarchy (SDH) standard developed by ITU (G.707 and its extension G.708) is built on experience in the development o ....etc

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
