Description
Technical field
It the utility model is related to technical field of wind power generation.More particularly, it is related to a kind of wind power generating set and its change
Oar system and pitch-controlled system fault test set.
Background technology
In Large-scale Wind Turbines, all mechanical parts of pitch-controlled system are all installed on wheel hub.Wind turbine is normally transported
All mechanical parts are all rotated with wheel hub with certain speed during row.The blade (root) of wind turbine passes through pitch variable bearings and wheel hub phase
Even, each blade has the relatively independent pitch drive system of oneself.Pitch drive system passes through a pinion gear and variable pitch
The engagement linkage of bearing internal tooth.At present, the tune paddle method of pitch-controlled system is：Rotated, become by pitch drive system drive pitch variable bearings
The rotation that paddle shaft is held drives the blade being installed on pitch variable bearings to be rotated, so that change the propeller pitch angle of blade as needed,
Realize and adjust paddle function.
One major function of pitch-controlled system is to control the rotating speed of wind wheel by controlling the angle of blade, and then controls wind
The output power of machine.In wind turbine during normal operation, when wind speed is less than unit rated wind speed, blade is reached 0 by pitch-controlled system
Angle Position is spent, carries out maximum power tracing；When wind speed exceedes unit rated wind speed, pitch-controlled system is by controlling the angle of blade
Keep constant the rotating speed of wind wheel.
Another major function of pitch-controlled system is to take on the service brake system function of unit, and electric variable propeller system passes through more
Kind detects and controls means, mutiredundant design ensures Wind turbine safe and stable operation.Shut down caused by any failure and all can

In in the wind wheel (or wheel hub) of wind-driven generator, its inner space is limited, is also fitted without the external condition of two systems.
The failure of paddle can not be returned for blade of wind-driven generator, still without relatively good control method, can only be overhauled as early as possible
Determine the device to break down, the device to break down is replaced.And it is complicated due to pitch-controlled system, when occurring therefore
During barrier, it is difficult to which it is which component there is a problem to accurately distinguish, and for smaller device, can easily use Shift Method
Quickly judge abort situation, and for bigger device, such as variable pitch driver, pitch motor etc., due to volume and again
The reason for each side such as amount, dismounting is relatively difficult, not only time-consuming but also laborious.Therefore, the variable pitch system of wind power generating set at present
The fault detect of system is time-consuming and laborious.
