Example Embodiment

[0032] See figure 1 with figure 2 , The present invention is a wind turbine test bench, which can simulate various working conditions encountered by the wind turbine during operation in the wind farm, so as to achieve full-function and full-condition testing of the converter before it leaves the factory. The purpose is to ensure the reliability of the converter in the wind farm.

[0033] The wind turbine test bench includes:

[0034] -Temperature and humidity control box, used to place the test object and simulate the temperature and humidity environment of the test object;

[0035] -Generators and their converters are used to generate electricity and convert the current into power frequency AC current;

[0036] -On-load tapping transformer, whose primary is connected to the output terminal of the converter, and the secondary is connected to the grid, used to adjust the output voltage to the grid-connected voltage;

[0037] -Drag the motor, which is connected to the generator through ...

Abstract

The invention discloses a test platform for a wind driven generator. The test platform comprises a power grid fault simulation device, a transformer, a dragging motor, a frequency converter, a generator, a current converter, a temperature and humidity control cabinet, a switch cabinet and a central control platform. The test platform is used for simulating various conditions of the wind driven generator during the wind field running process, testing generator properties and current converter properties of various generators, and especially testing the low-voltage traversing property of a machine set.
