Usefulness of DC Power Flow for Active Power Flow Analysis



I. INTRODUCTION
STATIC power system analysis has always been
performed using full power flow. It is one of the
fundamental tools for power system analysis and is used in
the operational as well as planning stages. Vertically
integrated companies have used it to control their systems, as
well as to plan the optimal economic operation of generation
resources, either by means of optimal power flow or unit
commitment. ....etc

Description.

This circuit can give a visual indication of the rate of air flow.It can be also used to check whether there is air flow in a given space.

The filament of a incandescent bulb is the sensing part of the circuit.When there is no air flow the resistance of the filament will be low.When there is air flow the resistance drops , because the moving air will remove some of the heat generated in the filament.This variations in the resistance will produce variation of voltage across the filament.These variations will be picked up by th ....etc

A new simple, effective and inexpensive method for lightning protection of medium voltage overhead distribution line is using long flashover arresters (LFA). A new long flashover arrester model has been developed.
It is designated as LFA-M. It offers great number of technical and economical advantages. The important feature of this modular long flashover arrester (LFA-M) is that it can be applied for lightning protection of overhead distribution line against both induced overvoltages and direct lightning strokes.
The induced over voltages ca ....etc

the air flow detector using led indicates the presence of air in the space by the variation of resistance and corresponding changes in the voltage. the glowing of led is depends on the presence of air. the large amount of air flow will decrease the resistance. ....etc

Definition: A device that's used in many electronic fuel injection systems for measuring the volume of air entering the engine. Some use a spring-loaded vane while others use a hot wire or heated filament to sense air flow.
A mass air flow (MAF) sensor responds to the amount of a fluid (usually a gas) flowing through a chamber containing the sensor. It is intended to be insensitive to the density of the fluid.
