Hello, the oscillation of the wind turbine, I only observe it at low speed and there is indeed a beat in the rudder (since the mast also oscillates). but all that disappears as soon as she accelerates a little. it always seems to happen at the same speed. For me the cause is probably in the wrong equ ...

Hello And to say that we are criticized for trying to reinvent lukewarm water !! With the above description we are close to the fuck up. It is a mistake to focus on the inertia of a 2m diameter rotor. It takes 2 to 3 seconds to go from 0 to 250 rpm or increase to 500 rpm. On a ...

Hello, I now think that it is about the phenomenon of stall following an excess of braking about which looping speaks. The stall does not generally occur in light winds, and therefore at low rotational speeds. If the blades stall, there is a hum and the roto ...

Hello everyone, What scares me is that we take as an example a network injection wind kit, which includes a Windmaster 500 inverter, to generalize on the regulation of the rotor speed. This inverter does not have MPPT function but MPP. There is no tracker but a simple ...

Bonjour,

Half-turn winding is easier, but less efficient

Hi Mach, We continue the conversation in mp. Too bad for the sharing of information but it pisses me off to be confronted with pseudo-experts who have never done or tested anything and to impress you send you back to work ...... others . Personally, I have other things to do ...

Hello, this regulator could it work after rectification and filtering (condo) of the current produced by the generator ??? in fact, what is the difference between a solar mppt and a wind reg mmpt (apart from the rectifier / filter part and the load shedding)? The algorithm of mppt regulators is global ...

Imagine placing a huge propeller on a small alternator. If the electromagnetic brake of the alternator is insufficient, the rotor will race, even by short-circuiting the phases. In this extreme case, I is maximum and u = O. So you should never (theoretically) find yourself in c ...

Hello everyone, Mach, great achievement! Nice to find you on the forum after such a long time. But such a beautiful baby, it takes a long time to develop. Mastervolt and SMA did not persevere in the development of the mppt for wind turbines and preferred to leave it to the user ...

Hello, The values ​​0 and 4 define the voltage range at which the alternator will work. This is probably the DC voltage after the diode bridge. It is logical that the 7.8 A are displayed automatically since the maximum power acceptable by the inverter is 500W. 70V x 7.8A ...
