Low-voltage induction hydro generators and wind generators, 100–2000 kW
Country: Serbia · Model: Asynchronous generators
Low-voltage induction hydro generator for small hydropower plants, working in parallel with the grid, rated 100–2000 kW, 400–690 V and 50 or 60 Hz. It has no excitation system, because the machine takes magnetising current from the grid or from a capacitor bank.

Description
The generator delivers active power when the turbine turns the rotor at a speed slightly above synchronous. This scheme is simpler and cheaper and needs no synchronisation on connection, so it is used at small plants without voltage regulation or stand-alone mode. Shaft height 280–900, from 4 to 20 poles, direct coupling to Francis, Kaplan and Pelton turbines. Class F insulation, IP23 protection with IC 01 or IP55 with air-tube cooling IC 511 or heat exchanger IC 611. Mounting is horizontal IM B3, B5 or vertical IM V1.
How to choose
The plant needs a grid of sufficient power and reactive power compensation. If voltage regulation or stand-alone operation is needed, take a synchronous generator, for example the compact one at 100–5000 kW. The manufacturer's list also includes induction wind generators, but there is no data table for them, so power, speed and nacelle version are requested separately.

FAQ
Why does an induction hydro generator have no excitation system?
It gets magnetising current from the grid or from a capacitor bank, so it works only in parallel with the grid and without stand-alone mode.
What power and voltage do induction hydro generators have?
From 100 to 2000 kW at 400–690 V and a frequency of 50 or 60 Hz.
Which turbines is the generator coupled to?
Directly to Francis, Kaplan and Pelton turbines, with 4–20 poles and a shaft height of 280–900.
Is there data on wind generators of this series?
They are mentioned in the list, but parameters are absent on the site. Power, speed and cooling should be requested from the manufacturer.
What protection and cooling options are there?
IP23 with IC 01, and also IP55 with IC 511 or IC 611. Mounting IM B3, B5 or V1.
