Description
Technical field
The present invention relates to the technical fields of draught fan performance test, refer in particular to a kind of big Megawatt fan performance test frock
And the test method realized using the tooling.
Background technology
Known in the industry, the performance for understanding, evaluation and analysis each parts of wind turbine usually carries out various testing experiments, surveys
The purpose of examination is：It was found that various defects of the wind turbine in design, material and technique etc., through analyzing and improve, make wind turbine can
Gradually increased by property, is finally reached scheduled reliability level, while can also be complete to improve the war preparedness of generating set
Property, reduce maintenance cost provide safeguard, meet defined reliability quantification requirement to determine whether wind turbine meets, as power whether
Reach target etc..Currently, wind turbine, towards ultra-compact, the direction of big MW class is developed, and the maintenance and replacement of fan are brought
The big MW class such as inconvenience, especially offshore wind turbine requires the performance reliability of each parts of wind turbine also higher and higher.
For the reliability of guarantee fan performance, then wind turbine is tested for the property, in Wind turbines model machine R＆D process,
Such as in the case of no conventional complete machine full power trial (FPT) platform, it can not be surveyed by Partial Power to being tested after final assembly
The method of examination carries out performance verification to Wind turbines to be particularly important, however then needs draught fan performance test by certain
Bill is tested to carry out, therefore there is the demands for probing into big Megawatt fan test method, to ensure that fan test reaches pre-
Phase purpose.
Invention content
It is an object of the invention to overcome big Megawatt fan centering relatively difficult, on the basis of time-consuming, for big
Megawatt fan performance test problem, it is proposed that a kind of good economy performance, big Megawatt fan performance simple and reliable, easy to use
Test fixture and the test method realized using the tooling.
To achieve the above object, technical solution provided by the present invention is as follows：
Big Megawatt fan performance test frock, the big Megawatt fan in the performance test, need to be configured with one
The small Megawatt fan of platform drags it, and is by the tooling between the big Megawatt fan and small Megawatt fan

In test, small Megawatt fan rotating speed is slowly increased to rated speed from zero, and big Megawatt fan is carried out with this
Partial Power is tested, and tested wind turbine output power ability mainly according to small Megawatt fan, determine under corresponding rotating speed by dragging capabilities
It is fixed；Wherein, the efficiency of the several critical components of the transmission chain of wind turbine is respectively：Gear-box >=0.96, generator >=0.95, frequency converter
>=0.98, the efficiency of flexible clutch takes 1, and the transmission chain that small Megawatt fan dragging capabilities subtract two Fans is lost to obtain big
Megawatt fan exports measured power；Test process is broadly divided into no load test and load test two parts：1) no load test mistake
Cheng Wei：The power generation mode of original frequency converter is revised as dragging operation mould by the frequency converter method of operation for changing small Megawatt fan
Formula provides power initiation operation to the generator of small Megawatt fan, drags the transmission chain rotation of big Megawatt fan, checks big
Rotating speed is stepped up after the transmission chain normal operation of Megawatt fan to rated speed, continues to run until the stipulated time, is completed empty
Carry experiment process；2) load test：After the completion of no-load test, under big Megawatt fan rated speed, big MW class is given
Torque reference is stepped up setting value, detects big Megawatt fan by fan frequency converter torque, control wind turbine to grid generation
Gear-box, whether generator, frequency converter, lubricating system, master control system meet design requirement, and add in big Megawatt fan
It carries under operational mode, efficiency test, vibration-testing, noise test these correlation test projects can be carried out, it is big by million to complete
The performance test of watt grade wind turbine.
Compared with prior art, the present invention having the following advantages that and advantageous effect：
1, the present invention drags big Megawatt fan by small Megawatt fan, can as far as possible the feature of simulates blower fan and
Working method reaches the test to big Megawatt fan with this, and can ensure that tested wind turbine will not be made during the test
At damage, the big Megawatt fan model machine of no full power trial (FPT) platform is developed especially suitable.
2, the test fixture that the present invention uses is to carry out transition connection with rope (being specially nylon rope or high intensity hawser)
(namely flexible connection), has the characteristics that flexible clutch, and wind can not be adjusted when can be effectively avoided in this way using rigid connection
The position of machine and the requirement that merging precision cannot be met.
3, the present invention is connected using flexible structure, it is easier to which installation and implementation, operability is convenient, saves cost, and operate
Person can be according to actual conditions, active control test process.
