Power System Small-Signal Oscillation Stability
as Affected by Large-scale PV Penetration



W. Du, H. F. Wang, and R. Dunn



Abstract —

This paper investigates the impact of a large photovoltaic (PV) penetration on power system small signal oscillation stability. A comprehensive model of a single-machine infinite-bus power system integrated with a PV power generation power plant is established. Numerical computation of damping torque contribution from the PV power plant is carried out, wh ....etc

Definition
The basic principles of Dual Energy X-ray Absorptiometry have been discussed in this presentation. DEXA is a instrumental technique used to measure bone mineral density (BMD), which is the widely accepted indicator of bone strength. DEXA scanner is the most widely used modern electronic machine to diagnose the disease osteoporosis, the thinning of bones. Human body being a heterogeneous system, use of a dual energy, rather than single energy, X-ray source is necessary for scanning. The interaction of the sample with the X-ray beams ....etc

Introduction

The earliest version of the CRT was invented by the German physicist Ferdinand Braun in 1897 and is also known as the Braun tube. It was a cold-cathode diode, a modification of theCrookes tube with a phosphor-coated screen.

A cathode ray tube is a vacuum tube which consists of one or more electron guns, possibly internal electrostatic deflection plates, and a phosphor target. In television sets and computer monitors, the entire front area of the tube is scanned repetitive ....etc

CRT MONITOR cathode-ray tube



Disadvantages of CRT

They have a big back and take up space on desk.
The electromagnetic fields emitted by CRT monitors constitute a health hazard to the functioning of living cells.
CRTs emit a small amount of X-ray band radiation which can result in a health hazard.
Constant refreshing of CRT monitors can result in headache.
CRTs operate at very high voltage which can overheat system or result in an implosion
Within a CRT a strong vacuum exists in it ....etc
