Induction type alternator and synchronous generator.
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..
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.
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.
If a self-excited generator lost all its residual magnetism, can it build up an output voltage?
what ever the advantages does a induction generator has in industry the same in college
an induction generator
how reversing an ac single phase induction motor to wark as induction generator

Generator
A generator uses electromagnetic induction by moving a coil of wire through a magnetic field. As the coil moves, it cuts through the magnetic field lines, inducing a current in the coil according to Faraday's law of electromagnetic induction. This current is then transferred out as electrical energy.
Energy is transferred by a generator through electromagnetic induction. As the rotor inside the generator spins, it creates a changing magnetic field that induces a current in the wire loops of the stator. This current is the electrical energy that is then transferred out of the generator for use.

in case of induction motor the rotor speed is less than synchronous speed giving positive slip but in case of generator the rptor speed is greater than synchronous speed giving negative slip.......

By definition a synchronous generator must be synchronous. If it is not "locked in" it is not a synchronous generator, but an induction machine.
