I need a 2KW turbine, HELP

[Milan Slovak]

Hi all,

Looking to get a new 2KW turbine to Grid Tie with my Aurora controls.
I am having a hard time finding a 2KW grid tie turbine here in the states.
Anyone have any suggestions.

I have looked into Advanced Power Systems, Hummer, and Airdolphin units.
All have very different pricing.

Any help would be appreciated

Hello Milan,
It is not so difficult to put a 2kw on the grid with a aurora inverter however,
the 2kw hummer will give riso errors (earthfaults)
and is a single phase noise generator
lots of power but also lots of noise

the SWG 2kw generator is 3 phase and almost silent in operation
the max power is about 3,2 kw in 16 Ms wind so you need a aurora 3.6 or higher.
you need to build a controller that will dumpload attack at 230-240 volts dc
the RPM of this generator is almost liniar with the voltage x 2
so you must prevent the generator to spin up higher as the 240 volts rectified dc output.
there for you need 3x a 1000 watts dumpload that must be switched in the AC site of the generator.
switch it in triangel over the 3 phase of the generator , and set the trigger voltage on 230-240 volts.
let the dumpload fall off at a 170 volt level.
so you are pumping with the generator between 240 and 170 volts.
and you have to wire the main relays in NC (normaly closed)
then the dump will come on when you have a grid failure.

OFCOURSE THIS ONLY HAPPENESS WHEN THE AURORA IS OFF THE GRID OR THE POWER FROM THE GENERATOR EXCEEDS THE MAX POWER OF YOUR AURORA.

You need to put a table in the aurora that can handle the 2kw SWG turbine.
We have this and i can mail it to you if you like.

keep in mind that a free running 2kw generator can easely go up to 600+ dc and destroy the aurora.

thats why you have to keep much attention to producing a good working controller system.
the controller must be able to hold the generator in range , also when no aurora is attached.
IN ALL SITUATIONS.
I suggest to put your aurora far away and test the generator and controller a while in all wind conditions.
remember your aurora is NO DUMPLOAD.

good luck :D

Hello. I overhauled my SWG 2000. I entered the power curve many times, but it is still wrong. This is visible in the behavior of the blades, so much so that with a DC voltage of 230V there is no tail deflection and the power reaches 4kW. Aurora has only 3.6 kW. Braking from 235vdc. Can you send me the data for the power curve? You're welcome, best regards
