Huaya 20kw pitch controlled wind turbine adopts:

 

Passive electric pitch controlled, tailless wind turbine. Controller will test the rotation speed,output voltage,current... Once the rotation speed/voltage/current is too higher, it will push the blades angle twist and change itself aerodynamic characteristic to control wind turbine rotation speed, till the blades direction same with the wind direction and stop working. This will make the generator output power steady and constantly.

Thanks!

• 1. Wind turbine model selection

 

It depends your local annual average wind speed, daily/monthly home power consumption. 

 

Low average wind speed place, select larger blades rotor, higher rated working voltage;

 

Rich wind place select speed limited wind turbine: variable pitch wind turbine, stall out vertical axis wind turbine.

 

The safety and steady working system is the first choice. 

 

2. Wind turbine tower selection

 

Now we have guy wire tower, stand alone tower, tilting up tower, hydraulic tower. 

Guy wire tower cost is lower, easy to delivery. But the installation area is larger;

 

Tilting up tower is for 500w-5kw wind turbine.  Easy installation, small installation area. But the delivery cost is higher. 

 

Hydraulic tower: It is used for no crane place. Easy installation and put down. The cost is higher. 

 

Stand alone tower for the installation place with crane. 

 

The tower height:  Make sure blades rotor is higher than wind turbine surrounding barrier height. 

 

3. Working system selection

 

On grid system: wind turbine with tower + PWM controller with dump load + grid tie inverter;

 

Off grid system: wind turbine with tower + PWM charge controller with dump load + battery group + inverter;

 

Wind solar hybrid on/off grid system: Safety and reliable than only wind or solar system.

 

Wind turbine water heating system: work in rich wind place. Average wind speed higher than 8m/s. 

For more question, pls contact with us directly.  We will give you a professional response. 

 

Why select us:

 

We are the wind turbine designer and manufacture. We know our wind turbine advantage and disadvantage in different wind condition.

 

I have more than 10 years wind turbine sales experience. We provide the right wind turbine and working system to different user according to their different situation and request. 

In 2004, there are 4 small wind turbine manufacture. Now there are so much trading company and manufacture, we know Chinese small wind turbine market well and can provide user more useful advise.
