Thanks for your reply. Can you give me a link from where I can study the operation of islanded generator in more detail. I wish to understand how frequency is different for different speed in case of islanded generator unlike the case of the generator which is connected to the grid. Is there...

Thanks a lot for all your replies. They were really informative. Sorry for the mistake....I wanted to write braking and not braking. Can anyone give me somelink from where I can study operation of islanded generator in detail

can anyone give me a detailed description of working of isolated induction generator or self excited induction generator it has been mentioned about it in the following link in the last paragraph but no details are given...

So, you mean that it is possible to have -ve slip of about -3 to -4 but the torque will be very low due to low current and high leakage impedance.

Are you sure that you are right? Here I am talking about generating action and in generating action. In generating mode the frequency of the rotor will be slip*supply frequency. Even the frequency at the stator supply remains same as is the bus voltage. So, I don't understand how you are...

for reference see the character-stick curve on the 4th figure of the page displayed by the following link: http://electricalstudy.net/lesson/torque-slip-character-sticks/ Why the portion of curve with speed above twice the synchronous speed been shown in generating action? Will there be...

yes you are right. with more than double the synchronous speed in direction of rotating magnetic field the machine will act like a generator. All I wanted to know was that will there be any kind of action equivalent to breaking action that usually happens when slip is between 1 to 2. because...

when the rotor will rotate at more than double the synchronous speed in direction of the rotating magnetic field then slip will be less than -1. Can anyone refer me a link where i can study such character-stick curve for induction machine.

Can anyone tell me that what will happen if I make the rotor of induction generator to rotate at more than double the synchronous speed i.e. I mean that how will the machine behave if the slip is less than -1.Will it simply behave like an asynchronous generator or will there be some breaking in...
