1-2 Wind Turbine Description
The major components of the wind turbine are shown as Figure 2.
A. Blades / Rotor System
The rotor system consists of three glass/carbon fiber blades. The glass/carbon fiber blades are
structurally strong because there are extra glass/carbon reinforcing fibers layers that hold the full
length of the blade. The blades absorb the energy of the wind and convert them into rotational forces
that drive the generator. The rotor system includes three blades because three blades will provide
excellent balance between the cost and efficiency and can run much smoother than two blades rotor.
※Warning：
The composites blades are very strong in tension, but they are susceptible to impact damage. They
should be handled carefully to avoid any impact during installation.
B. Generator
The generator converts the rotational energy of the blade/rotor system into electricity. It is a 3-phase
permanent magnet generator of an 18 pole structure. The generator is a completely new design for the
wind power system and could produce power at low rotating speeds. The output of the generator is
three-phase variable-frequency alternating current (AC), but it can be rectified to direct current or
connected to power grid through a grid-tied device.
C. Central Body Assembly
The central body assembly consists of the blade hub, generator casing, and the nacelle. It is the main
structural “backbone” of the rotor system, the generator, the yaw bearings, slip-ring assembly, the tail,
and the tower mount. The yaw bearings allow the wind turbine to turn around the top of the tower in
order to head the wind. The slip-ring assembly is the electrical connecter to connect the movable part
of the wind turbine and the fixed tower wiring. The slip-rings and yaw bearings are located inside the
tower mount. The tower mount attaches wind power system to the top of the tower through the tower
mount adapter.
D. Tail Assembly and High-Wind Protect (Furl Protect) Function
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 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.

1-4 Grid-tied Wind Power Inverter Description
This product is a wind energy utility grid-tied system. Single-phase grid-tied wind power inverter is
different from traditional stand- alone type wind energy inverter; it does not need additional expensive
and large space required energy storage battery, hence free from considerable battery maintenance
expense. It efficiently converts power generated from wind turbine, high efficiently converts to AC
power and feed into grid, having the direct benefit of power generation and energy saving.
1-5 Wind Power System Operation
A. Normal Operation
The generator of wind power system should begin to generate electricity when the wind speed reaches
approximately 3 m/s. The rotor rotational speed will increase with higher wind speed. The generator
output is proportional to the third power of wind speed. Please refer to Figure 3 for the relationship
between power output and wind speed.
Figure 3 Power Curve: Wind Speed vs. Power
※Note
The operational wind speeds and performance in the manual assume the condition of sea-level altitude,
steady winds, and moderate temperatures. High altitude, hot temperatures, turbulence and gusting
winds will usually bring the system performance lower than expectation.

10
B. High-Wind Protection (Furl Protection)
In case of high wind speeds, the High-Wind Protection Function system will protect the wind turbine
automatically. When furled, the rotor will turn away from the wind direction, the rotor speed will
reduce, and the power output of the turbine will be significantly reduced.
High-Wind Protection Function is an easy method to provide high wind speed protection. The
High-Wind Protection Function is based on basic physical relationship between the aerodynamics,
rotor, gravity, and the specially designed tail shape and weight balance of the wind power system.
The High-Wind Protection Function is completely passive, so it is very reliable. But there is one
situation in the field that we have found can disrupt the operation of High-Wind Protection Function.
If the wind turbine is installed on a sharp hill or next to a cliff so that the wind can come up through
the rotor on an incline (e.g., from below; as opposed to horizontally) this will affect furling and can
produce higher peak outputs. We strongly recommend avoiding this situation.
※Caution
The weight distribution of the system is specially balanced. Any change of the system weight and
balance, especially the tail, may cause malfunction of the High-Wind Protection Function.
※Note
Additional Electromagnetic Brake Protection Function is provided by the electronic system controller,
please refer to Chapter 4 Protection.
