Generator: Three phase permanent magnetism synchronous generator.
Generator Design theory formula: P = KD2 Ln " D ": Rotor diameter, " L ": Rotor length, " n": Generator rotating speed.
Magnetic material selection: T ≤ 160, material name:
Parameter selection: Secret.
Magnetic material Computation basis:
BSm = σµ 0Hδ Sδ
Vm =σµ 0 Ks Kδ Vδ H2δ / BH
Hm = 2KsKδ Bδ δ /µ 0 H'c
Stator material selection: >10000. Colding rolling.
Blades design theory:
A). Wind energy utilization factor:
B). Wind energy power: P = 1/2 Cp p AU3
"Cp ": Power factor; "A": Sweeps the wind area
"U": Wind speed; "p": Air density ( 1.225kg/m3)
C). Rated power and the wind-driven generator sweeping-wind-area best ratio.
D). Single blade length.
E). Blade apex speed should less than 65m/s, noise should be controlled at 400m Equates with the environment.
7) breaking system:
Mechanical electronic control. With CPU test the signal, with Servo electrical machinery hydraulic system to break it.
Functions: Manual breaking, automatic breaking. Automatic restore.
Through wind speed wind under counter gathering wind energy information, with CPU control, then though servo motor-driven yawing.
