Difference between synchronous generator and synchronous motor?
ASYNCHRONOUS is a mode whereby events happens irregardless of control. SYNCHRONOUS are this same events but controlled by a timing and/or control
How does the starting of synchronous motor using dc generator as a load work-?
Starting of the synchronous motor using the DC generator creates a magnetic field.
How many types of AC generator are there?
Induction type alternator and synchronous generator.
What is the characteristics for a generator on a full load?
What characteristics are you looking for? At full load, a synchronous generator will be spinning at synchronous speed, providing real power (watts), and likely some reactive power (vars), or it may be taking reactive power from the system to help hold the system voltage down under light loading conditions.
When slip ring get negative charge in ac generator?
you apply dc voltage to slip rings in synchronous generators polarity will make no difference ( other than when it is first applied )
What is a potier triangle?
it is used to calculate the voltage regulation of synchronous generator
Why is the frequency of a synchronous generator locked into its rate of shaft rotation?
By definition a synchronous generator must be synchronous. If it is not "locked in" it is not a synchronous generator, but an induction machine.
Short Circuit test of a Synchronous Generator?
synchronous generator
Difference between synchronous generator and synchronous motor?
ASYNCHRONOUS is a mode whereby events happens irregardless of control. SYNCHRONOUS are this same events but controlled by a timing and/or control
Why is speed not normally used to control the armature voltage of a synchronous alternator?
Because if speed was used, the power system frequency would be changed. A synchronous generator spins at synchronous speeds. Synchronous generators 101: A typical synchronous generator will have a field winding (typically on the rotor, or rotating part) and a stator winding (the stationary part where power is supplied to the power grid). Current is injected into the field winding, turning it into an electromagnet. This field current is controlled by the Automatic Voltage Regulator (AVR). The more current supplied to the field winding, the stronger the electromagnet becomes, and the more power is required from the prime mover (whatever is supplying the power - steam turbine, for example) to keep the generator spinning at synchronous speeds.
How does good regulation affect the short-circuit current of an ac generator?
I assume by good regulation you mean a minimal voltage drop internal to the generator. Minimizing this will inherently increase the short circuit current, because it requires minimizing the internal impedance of the generator.
How does the starting of synchronous motor using dc generator as a load work-?
Starting of the synchronous motor using the DC generator creates a magnetic field.
How many types of AC generator are there?
Induction type alternator and synchronous generator.
What is synchronous machein?
mainly alternator,synchronous motor comes under the synchronous machine.a synchronous motor is not a self starting motor.if a synchronous motor moves with more than synchronous speed then it acts as a synchronous generator.
What is Regulation of alternator by synchronous impedance method?
It is conducting OC and SC tests on the given three phase alternator and determining the regulation by synchronous impedance method.
What is the characteristics for a generator on a full load?
What characteristics are you looking for? At full load, a synchronous generator will be spinning at synchronous speed, providing real power (watts), and likely some reactive power (vars), or it may be taking reactive power from the system to help hold the system voltage down under light loading conditions.
Which type of generator is used in windmills?
Synchronous generators
