6.3 Characteristic curve operation in "Turbine"
operating mode
As soon as the DC input voltage defined in the parameter <UpvStart> is reached, the
Windy Boy begins a number of self tests, measurement processes and synchronizes
with the mains supply. If the self tests are successfully completed, and the DC input
voltage remains above the value defined in <UpvStart> for the time defined in <T-
Start>, the Windy Boy connects to the mains supply.
As soon as the DC input voltage reaches the value defined in <UdcWindStart>, the
Windy Boy begins feeding power into the mains supply. As you can see from the
characteristic curve, the power fed into the mains supply rises with the DC input
voltage.
As soon as the DC input voltage reaches the value defined in the parameter
<UdcWindMax>, the Windy Boy 5000 / 6000 feeds the mains supply with the
maximum possible power. If the input voltage continues to rise, the Windy Boy 5000
/ 6000 continues to feed the mains supply at maximum power.
The characteristic curve ends at the maximum permissible input voltage of the Windy
Boy 5000 / 6000, which must never be exceeded.
If the wind strength is so low that the DC input voltage falls below <UpvStart>, then
the Windy Boy ceases feeding power into the mains supply for the period defined in
<T-Stop>.
If the DC input voltage increases again, then the Windy Boy will again operate
according to the characteristic curve.
If the DC input voltage falls below the internally calculated minimum operating value
of <Vmin>, then there is insufficient energy for the on-board electronics and the
Windy Boy will switch off.
If the DC input voltage lies between <Vmin> and <UpvStart> for the time defined by
<T-Stop>, then the Windy Boy will also switch off.
After the switch-off process, the whole process begins anew.
Please note: The linear characteristic curve of the Windy Boy 5000 / 6000 only
approximates the actual characteristics of a real wind generator. Consult the
manufacturer of your wind generator for the typical characteristics of your
generator before changing the characteristic curve parameters.
Only change the operating parameters when you know exactly what you are
doing!
