New energy power generation

The increasing power of wind turbines has resulted in blades weighing several or dozens of tons. To manipulate such a huge amount of rotational inertia.

And the response speed required to keep up with changes in wind speed is quite difficult. Variable pitch wind turbines put into operation in recent years - face.

The blade Angle is controlled by variable pitch, and the rotor current of generator is controlled by frequency converter on the square side to control its speed. Pitch control is A relatively slow process, its action time is calculated in seconds, for the rapid change of wind speed power output effect is not ideal, and frequency conversion.

The actuator controls the current frequency of the generator rotor in milliseconds or less. Therefore, when the wind speed changes at a high frequency, the frequency converter instants.

Changing the current frequency of the generator rotor can ensure that the generator set can keep up with the frequent changes of wind speed, so that the power output of the generator set is stable and reduced.

It also reduces the operating frequency of variable pitch mechanism and prolongs the service life of variable pitch mechanism.

Q: Do you supply pattern ? Is it free?

A: If the pattern is low value, we will grant the free pattern with freight collect. But for some excessive fee samples, we want to gather the pattern charge.

Q: What is your time period of payment?

A: 30% down charge earlier than producing and 70% stability charge earlier than shipping.
