whether or not the wind turbine stores any energy... it certainly does...
BUT ELECTRICALLY IT DOES NOT.. it is a voltage source and a resistance... there is no capacitance, inductance is trivial at 10hz line.
But it doesn't matter whether the storage is mechanical or electrical. What is seen at the generator output is the same.
The wind, turbine, and generator form an equivalent cricuit like this:
- Voltage source proportional to square of the wind speed.
- Nonlinear variable resistor - approximate it as linear for RPMs between freewheeling and stall (i.e. max power RPM is about half freewheeling RPM) - with a value in that region inversely proportional to wind speed (i.e. max current at optimum load goes up with square of wind speed)
- Capacitor (HONKING BIG one), with value a function of the turbine's moment of inertia and volts/RPM, with genny's EMF equal to its charged voltage (iproportional to RPM),
- Resistance of genny's windings (and we're actually electrical from here on out).
Electrically it doesn't matter at all if the voltage source, wind, and capacitor of the model are electrical components or wind, aerodynamics of the blades, and spinning mass. The result is the same.
What i am concerned about, and indeed, just about saying its impossible, is to bring your turbine out of stall (tsr 2-3) and get it up to 8 where it belongs.
you can't do this with phase control, but your alternator could certaily handle it with a resistive load.
But you CAN do it, trivially, with a switcher AFTER the rectifier.
