Why choose pitch control wind turbine?
Leading technology-intelligent control, strong system scalability
1. The world's best wind power control technology is combined with the self-developed variable pitch technology.
2. The hardware design uses international well-known brands, and the software uses redundant control strategies.
3. It can achieve good compatibility with various well-known brand converters and remote modules.
High security-continuous operation around the clock to achieve unattended operation
1. The speed of the wind wheel is controlled, and it runs continuously and stably under severe wind conditions.
2. More than a dozen redundant control strategies ensure the safety and stability of the system in all climates.
A lot of power generation-variable pitch control, high-efficiency output, power generation up to 30%
1. Above the rated wind speed, the pitch angle of the blades can be adjusted to achieve continuous full power output.
2. The working wind speed range is large (3-25m/s), and the effective running time is long.

Products Description
Using the world's leading mechanical centrifugal variable pitch technology, the average annual power generation is 30% more.
(1) Large initial blade angle (+9 ), excellent acceleration performance, start at low wind speed of 2.5m/s;
(2) Below the rated wind speed, the wind turbine outputs efficiently;
(3) Above the rated wind speed, adjust the pitch angle so that the rotor speed is maintained near the rated speed and the power output is stable.
