Problem: that wind power does not debit




by sylvain560 » 12/03/12, 19:04

Hello

Thank you in advance if quelq one can help me.
J did ask a wind turbine by a company but this one deposit to the balance sheet after just coming.

My very little problem passing watts and wind idles

rough diagram of the facility

eolienne phase 48v type EOL5 (not bought from them)
I
I
switch
I
I
regulator / controller -------- discharge resistor (load dump)
I
I
I
I pswgt1200 ------------- -------- UPS UPS pswgt600
Battery
12v * = 4 48v



Connected to consometre watt inverters with instantaneous display and the will to EDF


my tests

Coupe (open switch) between regulator and wind
the wind picks up speed

Cut between controller and inverter
the wind picks up speed and tension rises

Doing tests with / without batteries IDEM

Observations

Controller over 54v continuous, surplus goes to resistances

Took out the voltage regulator is going to the batteries and inverters, although we 48v as displays regulator

Of that one branch 1 or 2 inverter voltage s collapse until the UPS start threshold and the wind slowed

First operating range inverter 28v to 52v, I have purchased another with an operating range of 14v to 30v thinking c 1 was lack of wind but ditto

Took the problem upside down

Charge the batteries 4 vacuum 52.4v
coupled to the inverter 1200W
52v ----- 1400W
47v ----- 1070W
30v ------ 750W

The 4 batteries coupled inverter 600W
30v empty
20v ----- 250W
16v ----- 170W
15v ----- 130W

2 26.4 charged batteries empty
coupled inverter 600 W
24.4v ---- 460W
24v ------ 390W


Observations

If 2 inverters coupled c is ditto

if any standby in the house and that the minimum debit 250W inverters, the electricity meter turns upside down

1200W already changed a UPS in the same ditto mark

Summary

Battery EDF it works
Of the wind turbine at the entrance of the inverters ago juice
But when everything is connected the wind slowed down and trying to
A voltage inverter 26v 600w provided between 10W and 20W
ou
A voltage inverter 30v 1200w provided between 0W and 10W

If someone an idea, thank you to advance

"if everything is on standby in the house and the inverters flow at least 250W, the EDF meter turns backwards"

Patents immediately your solution !! Get customers quickly.


More seriously, according to your description of the problem lies in the wiring of your inverters.

If for the same wind, the wind slowed when you dial tone, or your inverters is that there is an emf opposite :

-either a wiring inverter is inverted (+ to -)

-either the call of connected network is too large relative to the supply voltage: voltage ratio of the supplied current and the current of the EDF network.

Where is the continuous voltage rectifier / alternative?

What do you mean by: "the surplus goes to the resistors" in "The controller above continuous 54v, the surplus goes to the resistors"?

Could you take pictures? Thank you.

An old French Electricity ca meter runs. A wheel. 2 sense.
A recent ca account. Sagem style. 1 sense.

Question beast: you wind ???
A little. Bcp. A madness. Not at all

is normal because the wind begins to be hampered by the power drawn by the inverter, offering more resistance to the wind on the blades, like putting a brake him (the electromotive force against the current flowing from the alternator to the inverter).

The problem is that power taken by the inverter, if excessive, inadequate wind on wind, then it slows down too much, the inverter does not have enough power then, and rests, the wind off again in cycle.

This is poor design or inappropriate setting to wind inverter, wind classic problem already presented on econology (see Bidouille), with time constants and gains control, which oscillate constantly, classical fault inadequate control.

Change inverter will not solve, because nothing is clear in the instructions and specifications of these inverters, the range of adjustment, and on the exact regulation and limits.

Also if the wind speed decreases too with its high inertia, the braking torque of the power drawn by the UPS, it is impossible to remove.

Exact.
But playing on the angle of the blades. With adjustment shims.
more angle, more torque. It helps to limit the fem brake (electro magnetic force)
Fewer angle: more speed. it does not help.
Thinning the hub + blades set also has a role. Because increases inertia: torque effect.

Judging my GTI, the emf is progressive.
Begins to trigger the inverter, and progresses handed the injected watt increases as the voltage drops and the intensity increases.

Any regulation, like the one Max is complex, can swing easily, gain and inadequate time constants (Theorem Niquist and others) and thus almost no settings, we remain in the dark, with oscillations easily .

Hello

Long after discussing with professional in France and Belgium
The result is, that my installation is "bogus"
Mixture installation on remote site and network and UPS injection made for the Photovoltaics. (Non adjustable, non-programmable)

After multitude of esais and long after noon with the wind .....

The result for the people who are problem (and not handy) or disconnected while doing a qq come to remove all

If not for those handymen or those who have the money to invest in this kind of facility

The regulator / controller, do keep the diode bridge
disconnect batteries
Buy and ask 2 500 mastervolt inverters
Debrider and create a power curve

The you will have something that works but remains the party security
A table with circuit breakers, a differential ....
Voltage control relay and intensity to curb the wind turbine in windy surplus

After if you install on gear and vibration you (my case), remove mat and wind.
ask mounting pads and a mat of fiberglass or for peace put a guyed mast

After all this, it works.
There is a Nantes rating to the company that makes but a very big cost
Otherwise c is possible and you will spend a lot of time because few people on the mastery of the wind turbine, and for those who mastered the subject is taboo c c is their livelihood

To answer previous questions

Yes my counter turns upside down for it is a wheel, with the new phenomenon known not electronic

Epascal when I told the rest of my voltage delivered by the wind turbine, when the voltage reaches 54v the controller / controller couples to the braking resistors to avoid voltage batteries

Hoping to have been clear

I do not know which of the two wind turbines installed, apparently this is the model for EOL5 3000 W equipped with an electronic speed regulator and voltage (brake system).

The description of EOL5 1000 W model does not speak.

I guess the incoherent circuit voltage measured by the regulator brakes the wind.

@sylvain560

I just read your post after posting mine.

I conclude that you have a wind EOL5 1000 W on pinion.
