Problems solved by technology

However, the experimental equipment of the two wind tunnel experiments is different, which will inevitably lead to equipment errors; in addition, even if the wind speed of the wind tunnel set in the wind tunnel experiment is the same, it cannot ensure that the wind speed of the two wind tunnels can be consistent during actual operation
Therefore, under the influence of various error doping, it is difficult to accurately obtain the power generation efficiency of the generator
In addition, the torque sensor used in the wind tunnel experiment of the wind turbine is a precision instrument with a small measuring range. The existing device lacks a braking protection device. Torque between huge, damage the torque sensor
There are two types of wind turbines: horizontal axis and vertical axis wind turbines, and the existing experimental equipment can only test one type of wind turbine. When conducting wind tunnel experiments for different types of wind turbines, it is necessary to design two sets of experiments for different types of wind turbines. device, which increases the cost of the experiment

Description

technical field [0001] The invention relates to the technical field of wind power generators, in particular to a wind power generator testing device and method. Background technique [0002] The progress of social civilization and science and technology cannot be separated from the development of energy application technology. With the increasingly obvious contradictions between environmental problems and fossil fuels, human beings cannot wait to develop and utilize renewable energy. With its large reserves, wide distribution and relatively mature development technology, wind energy has gradually become an important part of the world's energy structure. [0003] The capture and utilization of wind energy mainly depends on the wind energy receiving device of the wind turbine, and the wind wheel and the generator are the two core components of the device. The aerodynamic performance of the wind rotor and the power generation efficiency of the generator determine the wind ene...
