Wind generating set load testing system meeting IEC61400-13 standard

Abstract

The invention relates to a wind generating set load testing system meeting the international electrical committee IEC61400-13 standard. The wind generating set load testing system is characterized by comprising a subsystem and a master control system (3), wherein the subsystem comprises a wheel hub testing system (1), a tower top testing system (2) and a meteorological testing system (4); the meteorological testing system (4) is arranged at the bottom of a meteorological anemometer mast; the tower top testing system (2) is arranged on the top of a tower cylinder; the wheel hub testing system (1) is arranged in a wheel hub of the wind generating set and rotates with the wheel hub of the wind generating set when runs; and the master control system is arranged at the bottom of the tower cylinder. The wind generating set load testing system can be applied to verifying design load of the wind generating set, optimizing design scheme of the wind generating set, detecting quality of the wind generating set which leaves factory, avoiding safety accidents and the like and has high practicability.

Description

[technical field] [0001] The invention relates to wind turbines, in particular to load testing of wind turbines. [Background technique] [0002] With the rapid development of the wind power industry, dozens of wind turbine manufacturers and more than a hundred types of wind turbines have been newly added in China. However, due to the large market demand for wind turbines, most manufacturers of wind turbines design and manufacture in a hurry, and the wind turbines that leave the factory have not been certified and tested, especially the load test of wind turbines that is closely related to the safety of wind turbines. This leads to the frequent occurrence of safety accidents of wind turbines. [0003] In order to ensure the safe operation of wind turbines, the load conditions of wind turbines must be tested. The IEC (International Electrotechnical Commission) has promulgated the international standard for wind turbine testing (IEC 61400-13), which is used to standardize the...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the patent application for this invention is to check the wind turbines before they leave the factory to verify the functions of the wind turbines and the safety of the components. The method used in the patent application is based on its own needs and is not based on standards; the external test conditions are different: the wind turbine is dragged by the prime mover on the test bench to simulate the operation status of the wind turbine under different conditions; The test quantity includes the vibration and / or temperature of the wind turbine, and its sensors are only vibration and temperature sensors, that is, the parameters of the test are limited, and the scope of investigation is also greatly limited
