How many types of AC generator are there?
Induction type alternator and synchronous generator.
Why do you use induction generators in wind generation rather than synchronous generators?
If you use synchronous generator... you need rotor to rotate always in synchronous speed... practically it s not possible always to produce that speed by air flow... Air flow always varies...But using induction generator, you need to get speed to make slip as positive value.. it is always possible...so induction generator is best one..
Is capacitor bank needed for generator?
Capacitors are usually used in power systems to corect power factor, which is a ver complex feild. However, yes capacitors are somtimes used with induction generators. When an induction motor is used as a generator, the spinning rotor has no appreaciable magnetisim and so the motor cannot generate electricity. Carefuly selected capacitors overcome the this difficulty induction machines have in generating voltage allowing them to opperate indipendently from another conventional generator.
What is the purpose of an electrical generator?
An electrical generator is a mechanical device that functions to convert mechanical energy to electricity basically by electromagnetic induction to be used in production, manufacturing, oil and gas industry and etc.
How the doubly fed induction generator build up voltage?
If a self-excited generator lost all its residual magnetism, can it build up an output voltage?
