how does AVR of electric generators work?
112633
The function of the AVR is to automatically regulate the voltage of generators. As a load on a generator increases it's terminal voltage tends to droop.The AVR senses the drop in terminal voltage by measuring the generator voltage and boosts up the excitation to the field of the generator to maintain the terminal voltage at the set level.Similarly as the load on the generator falls, the terminal voltage is maintained by the AVR by reducing the excitation to the field. The AVR also measures the Generator stator current.\nThere are various types of AVR with lots of features/limiters like power factor limiter, stator capacitive current limiter, MVAR limiter etc. But basically, all function by controlling the excitation of the field of the generator based on the sensing of the Generator terminal voltage and stator currents.

There is nothing called a induction generator, but of course there is a AC machine called induction motor. \n\nThe basic difference between an induction motor and a synchronous motor is that while the rotor of the Synchronous motor is powered (by DC current) the rotor of induction motor is powered by induction from the stator. Both have there stator powered by AC.\n\nAs for the Synchronous generator, if you force a Synchronous motor to rotate, powering only its rotor and not powering its stator, an AC will be generated across its stator and hence it will work as a generator.

The generators will be installed by local licensed electricians. The electrician will get any permits that are required.

Electricity and magnetism are closely related.  When a current goes through a wire, it creates a magnetic field around the wire.  Similarly, if a magnetic field is moved past a wire, it can induce a current.\n\nA generator spins a magnet past a series of coiled wires, inducing currents in them.  Generators and alternators both work in this way.  The difference between the two is that in a generator, the current always goes in the same direction, while in an alternator, it switches directions due to the fact that the polarity of the magnet changes as it rotates.\n\nGenerators always produce Direct Current (DC current), while alternators always produce Alternating Current (AC current).\n\nThe difference in nuclear, steam, coal, oil and hydroelectric powerplants is simply in how the rotation of the generator is produced.  The generators work in exactly the same way in each case.\n\nSolar power is different.  In the case of solar power, the current can be generated in one of several different ways.  These are more complicated, however, and I don't know the specifics of how they work.  Sorry.

You've actually got several concepts and questions merged together.\n\nWhen you ask "how does the aerial setup the waves from only the ac signal?"  I assume you're asking how any DC components of the signal get filtered out?\n\nA transverse electromagnetic wave involves both a VARYING electric field and a VARYING magnetic field, appearing at right angles to each other and to the direction of travel of the wave.\n\nAny DC component has no varying component, therefore, no wave is generated.  Although DC flowing through a wire creates electric and magnetic fields, no wave is generated because there is no variance in the fields.  \n\nThere are other electronics concepts that require the changing electromagnetic fields of AC to work.  A transformer uses AC, not DC.  A capacitor will block DC signals, but allow AC signals to pass.\n\nAlso, as you indicated, an efficient antenna has a matched impedance to the signal source in order to maximize the amount of engergy propagated by the antenna in the desired direction(s).

To get voltage doubling, you basically charge up a capacitor on one cycle and on the reverse cycle, run in series with that capacitor so you have 2X the voltage. For a full wave voltage doubler, you need to have an innovative arrangement of rectifiers so that you can get full cycle charge at all times.\n\nA example of a genuine full-wave voltage doubler may be fonud here:\n \nhttp://www.kwarc.org/bulletin/99-04/tech_corner.htm

You need to know more information.  How many Poles does the Generator have?  How many windings per pole?  Is it synchronous or a-synchronous?  What is the reduction ratio between the turbine and the generator?  Does the generator utilize an armature, brushes, or slip rings?  is the generator self exciting?  At what frequency will the output be?

Recuperator is a heat exchanger which helps to boost the efficiency of gas turbine engines on those air is compressed, burned with fuel, and used to drive a turbine. \n\nAnd you know what is generator now just differentiate it

It is hard to describe exactly since the terminology can be adapted to many specific applications.\n\nA voltage regulator is a device that maintains the output voltage as close to a constant setpoint as possible.  By design, the input voltage is typically a couple of volts higher than the output.  This gives the regulator operating headroom to work and do its job.  If the input voltage drops below the regulator's setpoint (and minimum headroom), the output voltage will drop correspondingly as the regulator has no means to raise the output voltage, only cut it back to to the setpoint.\n\nThe voltage control unit may be a more sophisticated device that is capable of delivering feedback to the generator set to compensate for a voltage sag.  If the voltage control unit detects the input voltage to the regulator dropping close to the minimum input voltage, it may do something like increase the field winding current on the generator in order to increase the generator's output voltage, thus minimizing a possible voltage sag that the voltage regulator (and subsequent loads) may experience.

Here is something that may or may not help\n\nIf you take a largish non polarized capacitor\n≥45µF\nand you apply AC 120V 60Hz to one side of it\nwith no ground reference! \nyou can then place \na small wattage low voltage lamp across the \ncapacitor terminals and it will light.\n\nThis is a way to send power over a single conductor.\nI have done this.\nI think it would also work with a coil instead of a cap.\n\nAs far as I can tell\nTesla wanted to use this principle to \npower the Earth\nusing the earth as the single conductor.\n\ndo you mean generate electric power at the other site?\ndo you mean energize an electric generator?\nmaybe for a very focussed wave and relatively small distance or a tiny amount of power.\nBut that is sort of why we use wires so much!\n\ndon't RFID cards transduce a wave and send it back\nI mean technically that is an example right?

hey men first know wat is a turbine.\nA turbine is a prime-mover used to provide the mechanical energy required for the generator.\nPrinciple of generators:\nwhenever a flux linking in a conductor changes there is an emf induced in the conductor.\n\nhere the flux is provided initially by a battery or some electrical source and the mechanical energy is provided by the turbine.\n\nIf u see the Mechnical energy from the turbine is converted into electrical.\nRemember energy can be converted from one form to another.This is the basic law.

Depending on the size of the Battery. Find an electric motor that use the same voltage and connect an outside source to turn it. Motors work on the same principle as a generator (To be simple about this). If, you apply voltage to the motor it will turn, if, you turn the motor in some way; it produce voltage. You can test what I say with window fans. Take two and face them toward each other. Turn on on high and it will make the other fan turn. Take an AC volt meter and measure the voltage at the plug of the fan that being turned. The faster you can make the fan turn the better your output voltage. This work the same with a little electric motor for your generator. If, it run on 12 volts DC then it will output the same, if, it turned fast enough and actually charge a battery. Hope this enough to help.

Electromagnetic induction is basically the generation of an electric current in a wire due to passing through lines of magnetic flux, or changing flux.  This is the underlying principle in virtually all electromechanical generators in use today.\n\nProbably the easiest way to store the electrical energy would be in chemical form, such as a battery.  You could also store smaller amounts of energy in capacitors as well.\n\nWiring is simple, take a coil of wire and move it through a magnetic field.  The field can be from a permanent magnet, or from another coil of wire that has an electric current passing through it, creating a magnetic field.

First of all generator generates electricity. Electricity is tapped from armature of the generator. While in electrical motor , supply is given to the armature. As far as your question is concerned since the armature is rotating while magnetic field is stationary only way to tap the supply is through brushes. Continuous wire will break .

The generator consists mainly of a coil of wire wound over an iron core.This wire is connected to an external circuit where the current produced is either stored in capacitors or used to run a particular device. When the axle of the wire is rotated, magnetic flux linked with the wire changes and hence, according to Faraday's law, an electomotive force(emf) is induced in the wire as it is placed in between magnets having different polarities. Slip rings are present to allow the flow of the alternating current produced into an external circuit.

My God, I've never seen so much misinformation and confusion in my life.\n\nThe word "generator" is a generic name for a rotating machine which converts mechanical energy into electrical energy.\n\nThere are two types.\n\nOne type of generator is a dynamo, which produces d.c.\n\nThe other type of generator is an alternator, which produces a.c.
