Hi all,
I have been asked a question about generators, and it perplexes me. Someone I know has a set of resistive elements that require a large amount of kW, and the only way they have to power them is with a petrol-driven generator. However, it is insufficient. They do, however, have more than one.
Their question was this: is it possible to 'add' the generators together to provide enough power?
Obviously, they are not synchronous generators, so my thinking was that they would certainly be out of phase. However, I have no idea what would happen if you connected them in parallel. Any difference in waveform would fry the connection, would it? Or would they force each other into synchronisation?
The motor cuts the lines of flux => alternating current, one phase. This is connected to another two motors (ignoring the resistive element). Say they are off, the ac going in would then turn the motors (?), and if they are on, they would be forced into synchronisation(?)
Also, the power ratings for them are possibly not the same, at 5.5, 6, & 8 kW. If what I said is correct, two would be drawing power from the other to keep synchronised at maximum load..?
The load is just a resistive element thankfully, with ground, neutral and live.
If this is a bad idea (which I imagine it is), what about industrial-strength diodes to make them all DC (ish), thereby not interacting and easily put in parallel?
I might update this with more musings/looking through my course notes for later in the year.
