Wind generator vertical axis. Assembly by the user (KIT).
(FOB Tianjin CHINA) (Not included batteries and inverter).
Approximately Price: 3.150 euro
Model: WIND GENERATOR, WIND TURBINE THALES
   
Thales IV
Max power:
   
24 KVA/day with wind speed 5,66 m/s.
   
48 KVA/day with wind speed 9,28 m/s.
Wind generator output voltages:
   
12 DCV and 24 DCV and 48 DCV.
Generator model:
   
C8003.
Turbine rotational speed:
   
Maximum 404,06 RPM.
    To achieve this rotation speed, the wind speed should be 12 m/s. At this speed of rotation, the turbine delivers power of 95,598 Nm.
    Ideal 300 RPM (for turbine not for wind generator).
   

To achieve this rotation speed, the wind speed should be 8,91 m/s. At this speed of rotation, the turbine delivers power of 52,596 Nm.

    The relationship between the wind speed and the speed of rotation of the turbine is linear and is given by the formula: y=33,671375x. (R2 = 1)
    CHART 1 Wind speed - Turbine “Thales IV” RPM.
    The relationship between the wind speed and the power delivered by the turbine is given by the formula: y = 0,6669x2 - 0,0435x + 0,0745. (R2 = 1)
    CHART 2 Wind speed - Wind Turbine “Thales IV” power.
    The relationship between rotational speed of the turbine and the output power can be calculated by the formula: y = 2E-08x3+ 0,0006x2 + 0,0015x - 0,0488. (R2 = 1)
    CHART 3 Turbine “Thales IV” rotation speed - Power output.
Cut in wind speed:
    1,19 m/s. When the wind turbine is new, required a total power of 1,76 Nm (Newton meter) to start the spin of the turbine. But after two to three weeks of operation, the power required to start the rotation is 0,96 Nm.
    When the generator C8003 is installed in the wind turbine, then, without any load on the generator, the energy required to rotate the turbine is only 1,46 Nm. This is because the C8003 generator is coreless (AFPM), so it does not have resistance to rotation.
    The user defines the cut in speed with a corresponding adjustment of the controller.
Rated wind speed: 5,66 m/s (1000 VA) and 9,28 m/s (2000 VA). CHART 4
    The rated wind speed is of no particular importance with regard to the turbine, since its efficiency is the same at all operational wind speeds, from 1 m/s to 24 m/s.
The rated wind speed is important in relation to the generator, which is installed inside the wind generator. Thus, the nominal wind speed is the minimum wind speed, in which the wind generator, as a complete device (turbine + generator + controller) generates the nominal power.
    The rated wind speed is dependent on the power transmission ratio. CHART 4
 
a.

Gear ratio 3,125/1.
For an apparent electrical power of 1000 VA, wind is required at a speed of 9,93 m/s
For an apparent electrical power of 2000 VA, wind is required at a speed of 14,68 m/s.
Relative values can be calculated from the formula:

Relative values can be calculated from the formula:

Relative values can be calculated from the formula:
y = 2E-16x5 - 2E-12x4 + 5E-09x3 - 7E-06x2 + 0,0095x + 2,4921. (R2 = 1)

Gear ratio 1,5/1.
For an apparent electrical power of 1000 VA, wind is required at a speed of 6,88 m/s
For an apparent electrical power of 2000 VA, wind is required at a speed of 9,92 m/s.
Relative values can be calculated from the formula:
y = 2E-16x5 - 1E-12x4 + 4E-09x3 - 6E-06x2 + 0,0082x + 2,1596. (R2 = 1)

For an apparent electrical power of 2000 VA, wind is required at a speed of 9,28 m/s.

Gear ratio, turbine/generator: CHART 5
 
a.

3,125/1. The relationship between the speed of rotation of the turbine and the power delivered to the generator C8003 shaft, when the power transmission is 3,125/1 is given by the formula:
y = 8E-09x3 + 0,0002x2 + 0,0005x - 0,0156. (R2 = 1)

 
b.

2,5/1. The relationship between the speed of rotation of the turbine and the power delivered to the generator C8003 shaft, when the power transmission is 2,5/1 is given by the formula:
y = 9E-09x3 + 0,0002x2 + 0,0006x - 0,0195. (R2 = 1)

 
c.

2/1. The relationship between the speed of rotation of the turbine and the power delivered to the generator C8003 shaft, when the power transmission is 2/1 is given by the formula:
y = 1E-08x3 + 0,0003x2 + 0,0008x - 0,0244. (R2 = 1)

 
d.

1,5/1. The relationship between the speed of rotation of the turbine and the power delivered to the generator C8003 shaft, when the power transmission is 1,5/1 is given by the formula:
y = 2E-08x3 + 0,0004x2 + 0,001x - 0,0325. (R2 = 1)

 
e.

1/1. The relationship between the speed of rotation of the turbine and the power delivered to the generator C8003 shaft, when the power transmission is 1/1 is given by the formula:
y = 2E-08x3 + 0,0006x2 + 0,0015x - 0,0488. (R2 = 1)

 
From CHART 5 it appears that the shorter the cosine (the cosine value depends from the kind of load that we connect to the generator), the greater must be the gear ratio.
 
If the load is only resistive, the power gear ratio must be 1/1.
If the load is mixed (resistive, inductive, capasitive) as in CHART 5, then the power transmission ratio must be increased so that the power delivered by the turbine on the generator shaft decreases and the generator rotation speed increases accordingly. The use of different power transmission ratios is primarily intended to ensure that the generator operates at the highest level of efficiency.
 
At the initial installation of the wind turbine, the power transmission ratio is recommended to be 1.5/1, even if the cosine measurement shows a cosine of 0,99.
