Embodiment Construction

[0032] see figure 1 and figure 2 , the present invention is a wind power generator test bench, the test bench can simulate various working conditions that the wind power generator encounters when it is running in a wind field, so as to test the converter with full functions and full working conditions before leaving the factory The purpose is to ensure the reliability of the converter in the wind farm.

[0033] The wind turbine test bench includes:

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

[0035] - Generators and their converters, used to generate electricity and convert the generated current into industrial frequency alternating current;

[0036] - On-load tap changer, the primary of which is connected to the output terminal of the converter, and the secondary is connected to the power grid for adjusting the output voltage to the grid-connected voltage;

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.

Description

technical field [0001] The invention belongs to the technical field of testing, and in particular relates to a wind power generator test stand, which is used for performance testing of the wind power generator for factory inspection. Background technique [0002] In recent years, wind power has developed rapidly with the support of national policies, but with the continuous increase of wind power installed capacity, the status of wind power in the power system has changed. When the installed capacity of wind power is small, the impact of its operation on system stability can be ignored; when the installed capacity of wind power becomes larger and its proportion in the system increases year by year, the impact of its operation on system stability will change. cannot be ignored. [0003] In order to ensure the safe and stable operation of the power system, some power associations or power grid companies in Europe, North America and Australia have formulated technical guidelin...
