Abstract
The utility model discloses a wind-driven generator and a wind-driven generator set. The wind-driven generator comprises a wind wheel and a turning motor for driving the wind wheel to rotate. The wind-driven generator is characterized by further comprising a frequency converter, the output end of the frequency converter is connected with the turning motor, and the frequency converter can precisely control the rotation speed of the turning motor. By the arrangement, the rotation speed of the turning motor can be precisely controlled by the frequency converter during turning, normally a frequency converting motor continues rotating along with inertia, the frequency converter can stop the frequency converting motor suddenly after turning, the wind wheel is also prevented from rotating continuously along with the inertia, large impact on a gear box can be avoided, the frequency converting motor can be prevented from rotating for a long time due to the inertia by controlling the turning motor to stop suddenly through the frequency converter, turning time is saved, and turning efficiency is increased.
Description
Technical field
The utility model relates to technical field of wind power generation, more particularly, relates to a kind of wind-driven generator and wind power generating set.
Background technique
At present, in the time that wind power generating set is carried out wind wheel maintenance or Transmitted chains centering, need to carry out jiggering to wind wheel, along with the capacity of wind power generating set increases, wind wheel quality also increases, and the inertia of wind wheel is increasing.Therefore in prior art, the general jiggering motor that uses carries out jiggering to wind wheel, but jiggering motor is all generally the mode that adopts full voltage starting mode and free parking, so the inertia of wind wheel is larger, in jiggering motor shutdown process, the impact that the gear-box of wind power generating set is caused is larger, and wind wheel due to inertia stop after still rotate, make the jiggering time longer, and reduced jiggering efficiency.
In sum, how effectively solving the long and inefficient problem of jiggering of jiggering time, is current those skilled in the art's urgent problem.
Model utility content
In view of this, first object of the present utility model is to provide a kind of wind-driven generator, the structural design of this wind-driven generator can be separated the long and inefficient problem of jiggering of jiggering time effectively, and second object of the present utility model is to provide a kind of wind power generating set that comprises above-mentioned wind-driven generator.
In order to reach above-mentioned first object, the utility model provides following technological scheme:
A kind of wind-driven generator, comprises wind wheel and the jiggering motor that drives wind wheel to rotate, and also comprises the frequency variator that can accurately control described jiggering motor speed, and the output terminal of described frequency variator is connected with described jiggering motor.
Preferably, in above-mentioned wind-driven generator, described frequency variator can be controlled described jiggering motor and rotate and reverse.
A kind of wind power generating set, comprises multiple wind-driven generators, and described wind-driven generator is the wind-driven generator as described in above-mentioned middle any one.
The wind-driven generator that the utility model provides, comprises wind wheel and the jiggering motor that drives wind wheel to rotate, and it focuses on, and also comprises frequency variator, and the output terminal of frequency variator is connected with jiggering motor, and frequency variator is control panel vehicle motor rotating speed accurately.So arrange, can in jiggering process, pass through the accurate control panel vehicle motor of frequency variator rotating speed, such as making by frequency variator after jiggering, variable-frequency motor is anxious to stop, generally it is along with inertia is rotated further, also avoided wind wheel along with inertia is rotated further, and then can avoid gear-box to cause greater impact, and stopped to prevent that by Frequency Converter Control jiggering motor is anxious variable-frequency motor is because inertia rotates for a long time simultaneously, and then saved the jiggering time, improve jiggering efficiency.
In order to reach above-mentioned second object, the utility model also provides a kind of wind power generating set, and this wind power generating set comprises above-mentioned any wind-driven generator.Because above-mentioned wind-driven generator has above-mentioned technique effect, the wind power generating set with this wind-driven generator also should have corresponding technique effect.
