Need help with wind turbine development

[darwenn]

And yes, you had had the chip in your ear for a long time and I thought I checked the regulator and thought it was working but at that time I was not using an ammeter, just a voltmeter of which I was only measuring the output voltage and not the power, so I had not noticed the problem with the regulator. I made a table in fact with analog V and A galvanometers and on Saturday while the wind was blowing well, I did not understand this lack of power and this need for crazy rotation speed to output a few amps, there since this afternoon and my tests with the solar regulator I could see the problem directly and quickly. What is curious is that I no longer hear the "vouuuuuu" that the wind turbine was doing on Saturday when the amps were being sent. There it sends them at a slower speed and there is no longer this thud. Curious, this sound was coming from the generator and not from the blades at full speed.

You could only find a cheap wind turbine regulator that works well .. it will be less easy. can a car alternator regulator work?

PS:
I got a big 33000uf 100v capacitor. As I saw that it was interesting to connect it at the output of the diode bridge. I haven't tried it yet, I'll see if it changes anything in terms of power.

Hi Darween!

You can try the Capacitor at the exit of the diode bridge before your regulator, your problem maybe comes from there, if the voltage drops too quickly the electric can be disturbed and create this vroom in the motor because it turns on and off too quickly.

You can also couple your diode bridge directly to the batteries and control your battery voltage by starting the inverter as a regulator and switching to consumption.
Therefore you will have no loss in electronics.

The regulator of your alternator can very well do the job as a rectifier only and moreover it has a very good capacity in amperages, must be tested, I am very far from you to give you a helping hand physically unfortunately.

Hello Andre

Question to Andre Aircraft propeller specialist

How to protect the bort d 'attack propeller deolienne 1.90m
speed 800 tm with variable pitch automatic
With a brass or aluminum foil that it thickness
Epoxi glue i guess
Glue directly on wood and paint over or vice versa

Eole A + Thank you

You can also couple your diode bridge directly to the batteries and control your battery voltage by starting the inverter as a regulator and switching to consumption.

Yes, but the voltage at the output of the diode bridge sometimes rises to 30 volts, it is too much to directly supply the battery.

[Alain G]

Hello Darwenn!

30 volts is empty!

Do a test connected to the batteries and see what voltage it gives you because the batteries will regulate your voltage, you will have less losses, you can also add batteries and increase your capacity.

Hello Hello Wind Friends

Yes indeed, the big Condo, you place it parallel to the exit of the diode bridges, same as the big power supply.
After the voltage diode bridge * 1,414 - Conso pont…. Finally theoretically.

For the Savonius wind turbine. I think, to have more power, to mount a double Stator (of Coils), and only one Rotor recto verso, to follow So.

It is true that the switch which short-circuits the phases is effective, but certainly does not extend it.

Amount of energy to recover the wind turbine in 1 year; For my part, I have not yet made the point, to follow therefore also.

Me too it goes up to + 24 Volts, so connecting two batteries in series, and in addition, they serve as regulator.

About what type of regulator do you have? For my part, Classic Shunt Regulator .. But I'm interested in an MPPT ..

And very good your video, I like when the wind turbines go up in speed.
But what is this background noise?
Anyway, don't give up, you will do with the wind, which you will have, like me for that matter., I can assure you, the Mistral is not always present, on the other hand the Sun, it is good the .
But it works mine in parallel with solar panels, garden lighting and various.
Next objective, find cells and mount a Solar Panel. I have already made a small 15V 250 mA, a dozen cells, lighting my carport and wood, fun to assemble.

Come on Good luck to all and see you soon for our adventures

Well Ventic @ lement (good sorry that means nothing, but it's pretty)

"But what is this background noise of water?"

It's my garden pond, it's the fountain pumps and filter we hear

For Alain you are sure that there is no danger in sending 30v in a battery of 12? of course as I said I will capture the excess charge to deflect it. I had already done a test it's true by injecting directly, the voltage drops to 14volts if I remember correctly, when charged, the battery absorbs and the voltage stabilizes. But I told myself that it was not good, that the battery was going to explode in my head and I quit.

Mistralou, the regulator that I have was made according to an electronic scheme and which is said to be not bad. This is not the case, and yet my assembly is completely correct, it works but frankly too bad as a regulator and my wind turbine must deliver a maximum for it to load. Your regulator, did you buy or make it? if you made it I'm interested.

[Alain G]

Darwenn

If your voltage drops to 14 volts it is good now when the voltage reaches beyond 14.5 or 15 volts you deflect your production or you put your inverter on on other devices and there is no problem, as j I said above add batteries and you distribute the load over several which will be less difficult for your batteries in addition to giving you more autonomy.

[darwenn]

I keep this idea warm so to try

[Alain G]

Darwenn

You have to understand that the no-load voltage means absolutely nothing or almost, the higher the charge, the lower the voltage and the higher the amperage.

If you are around 40 amps which is the capacity of your generator then you can use it in 24 volts to extract the maximum of wattage, but as you are far from that, it is better to use it in 12 volts.
