Loading system for test platform of wind generating set

Abstract

The invention discloses a loading system for a test platform of a wind generating set. The loading system comprises a motor, wherein the motor is connected to a reduction box; an output shaft of the reduction box is connected to an input shaft of the wind generating set through a universal coupler; a load simulating part is arranged on a shaft position of the universal coupler; an electromagnet generating device is additionally arranged on at least one of up and down peripheries and left and right sides of the load simulating part; and the electromagnet generating device and the motor are respectively connected to a control system. According to a congruent relationship between a rotating speed of the generating set and an air speed and a thrust coefficient of the generating set, the control system of the test platform is utilized to solve a thrust value generated by the generating set and calculate a current value for generating the corresponding thrust and gravity by an electromagnetsystem, and the electromagnet system is utilized to load the load simulating part and simulate the thrust, gravity, bending moment parameter, and the like, of a fan under a practical wind condition.

Description

technical field [0001] The invention relates to a wind power generator test technology, in particular to a loading system for a wind power generator test platform. Background technique [0002] At present, the world's environmental situation is deteriorating day by day, among which the use of coal, natural gas, oil and other fuels to generate electricity is an important factor that produces the greenhouse effect. In order to alleviate the fossil energy crisis and protect the global environment, wind energy, as a new type of energy, has been vigorously developed by countries all over the world. However, due to the alternating and unstable characteristics of the wind itself, higher requirements are put forward for the reliability and stability of the wind power generating set. In order to be able to test and test the main parameters and performance of wind turbines, the wind turbine test bench is widely used by major manufacturers as the test equipment for wind turbines.

AI Technical Summary

Problems solved by technology

However, the test bench widely used in the market at present adopts the mode of dragging the motor to drive the gearbox and then directly connecting the input end of the wind turbine. Although the electrical performance and related parameters of the wind turbine can be tested, the test bench can only provide wind power The torque required by the generator set, but cannot simulate the thrust generated by the actual wind conditions on the wind force and the bending moment generated by the weight of the wind wheel on the main shaft system, so it is impossible to truly test the rationality and reliability of the wind turbine drive chain

With the increasing power of the unit, the reliability requirements of the unit are getting higher and higher today. The conventional wind turbine test bench that can only provide torque can no longer meet the testing needs of the wind turbine with the rapid development of technology.
