Can synchronous generator produce reactive power?
Synchronous generators can generate or absorb reactive power depending on the excitation. When overexcited they supply reactive power, and when underexcited they absorb reactive power.
Can a generator produce only reactive power?
DWQA Questions › Category: (EE) Power System › Can synchronous generator generates reactive power? Yes! In power systems, the reactive power flows from the higher voltage to the lower voltage, imagine one generator, your house, and a transmission line.
How active and reactive power is controlled in synchronous generator?
Active and reactive power control of synchronous generator for the realization of a virtual power plant. The independent control of active and reactive power is achieved through rotational transformations of the terminal voltages and currents at the synchronous generator’s output.
Why do generators produce reactive power?
Reactive power is mainly produced by Synchronous Generators through rotor field current (Generator Excitation). The larger the demand of reactive power in system is, the larger should be the Generator field current to meet that demand.
What is synchronous generator?
A synchronous generator is a synchronous machine which converts mechanical power into AC electric power through the process of electromagnetic induction. It is called synchronous generator because it must be driven at synchronous speed to produce AC power of the desired frequency.
How does generator produce reactive power?
How the reactive power of generator is controlled?
Control over the reactive output and the terminal voltage of the generator is provided by adjusting the DC current in the generator’s rotating field . Control can be automatic, continuous, and fast. The inherent characteristics of the generator help maintain system voltage.
Why does an over excited synchronous generator generate reactive power and an under excited synchronous generator absorbs reactive power?
An over excited synchronous generator generates reactive power as its excitation is increased (over excited ) means the magnetic field strength of the stator winding of the synchronous generator is now increased more by increase in DC excitation , so in such a case more flux will induce in stator winding and when this …
