4-1 Electromagnetic Brake Protection
This wind turbine system has two kind of electromagnetic brake protection function
:
Resistor and
Short-circuit Brake Protection. Using wind power inverter and brake control cabinet to perform this
protection function.
(1)
Resistor Brake Protection
:
When wind speed exceeds 13.5m/s, system will start resistor brake protection function. Then wind
turbine will slow down and system will disable resistor brake protection function and wind turbine
will operate normally.
(2) Short Circuit Brake Protection
:
When wind speed often exceeds 13.5m/s in a few minutes, system will start resistor brake
protection for 30 seconds and short circuit brake actives for 5 minutes.
4-2 High Wind Protection (Furl Protection)
The tail assembly, which includes the tail boom and tail fin, will keep the generator Assembly and
rotor facing to wind at wind speeds less than about 13.5 m/s. At wind speeds reaching approximately
13.5 m/s, the High Wind Protect (Furl Protect)
function actives and turns the rotor partially away from
the wind to prevent the rotor over-speed. That allows the turbine to continue to generate electrical
power before it reaching the safety shutdown control point in high winds. When the wind speed slower,
the High-Wind Protect
function will inactive and turn the turbine back to the heading wind position.
