Hydro plant minimum flow unit induction or asynchronus unit selection
Hydro plant minimum flow unit induction or asynchronus unit selection
(OP)
We are looking at retrofitting a new minimum flow unit of 400kW into an existing hydro plant - in this situation would you use an induction or asynchronus generator and why?






RE: Hydro plant minimum flow unit induction or asynchronus unit selection
What would be your source of excitation? Do you need to produce Volts or is it sufficient to just produce Watts? Probably lots more questions.

But I don't know first hand. I will be watching this thread with interest.

This, however, reminds me of the first wind farm I saw. Each unit was an induction unit with an installed capacitor bank. But the problems are that the units would draw more vars with increasing power output.
My concerns are that during a fault, some distance away, there would be almost no reduction in voltage to the unit, so I might expect some fault contribution.
Question: How much, ball park, should I expect?

Operation wise, I leave it to the experts to analyze which machine is better to operate and control. One drawback with induction machines is var requirement either from the grid or from the capacitor bank.
