we do not use induction generator because it require an external source (synchronous generator) that provide reactive power to it.
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.
The theory of converting AC to DC using a 3-phase induction motor and a DC shunt generator involves utilizing the induction motor to mechanically drive the shunt generator. When the induction motor is powered by a three-phase AC supply, it operates and drives the rotor of the connected DC shunt generator. This generator then converts the mechanical energy into electrical energy, producing a DC output. The process allows for efficient conversion of AC to DC, leveraging the motor's mechanical properties and the generator's electrical characteristics.
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.

Generator
There is a motor in a generator which carries out this electromagnetic induction,as we switch on the generator the magnetic field lines between that motor get cuts off by the rotating coil which cause change in flux and change in flux cause induced emf,cue to emf at different points of coil cause current to get flow and then generator will get on.
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.
