Wind turbine icing and weather resistance test system and test method

Abstract

The invention provides a wind driven generator icing weather resistance experimental system and method. The wind driven generator icing weather resistance experimental system and method are used for achieving the purpose that in the prior art, the energy of removing the attaching ice on fan blades needs to be researched. The system comprises a wind driven generator blade simulation device, an environmental simulation device and a heat energy consumption testing device. The heat energy consumption testing device provides the heat and tests the situation of temperature changes of the hot air existing before and after the attaching ice drops. The wind driven generator blade simulation device comprises an experimental cavity, a blade and a servo motor. The blade is arranged in the experimentalcavity through a rotating support. The end, connected with the blade, of the rotating support is arranged in the experimental cavity, and the other end of the rotating support is connected with the output end of the servo motor. The rotating support is driven by the servo motor to rotate so as to drive the blade to rotate. By the adoption of the wind driven generator icing weather resistance experimental system and method, the attaching ice removal force or amount under different natural conditions can be tested, and the result is more reliable.

Description

technical field [0001] The invention relates to the field of detection of blades of a wind power generator, in particular to an experimental system and a test method for the icing and weather resistance of a wind power generator. Background technique [0002] Wind power is becoming a craze around the world because it has no fuel issues and doesn't produce radiation or air pollution. The principle of wind power generation is to use the wind to drive the blades of the windmill to rotate, and then increase the speed of rotation through the speed increaser to drive the generator to generate electricity. Since the wind turbine is installed in a wide and windy outdoor environment, there are many tiny protrusions on the surface coating of the blades on the wind turbine to form a structure similar to the surface of a lotus leaf. The self-cleaning effect of the lotus effect is used to ensure that the blades are in good condition. The surface can be kept clean outdoors, and the blade...

Problems solved by technology

However, due to the dusty and windy working environment where the fan blades are located, the dust-proof structure on the surface is often damaged, so that the fan blades freeze after being exposed to damp or cold air in the working environment, and these are attached to the fan blades. The ice is a threat to the operation safety of the wind turbine, so it is necessary to remove these attached ice

Now the commonly used method is to heat the fan blades to melt the ice on the fan blades and remove the ice. At present, in order to remove the ice, it is necessary to add a large power when heating to ensure the removal of the ice. Therefore, the energy loss caused Waste, so it is necessary to study the energy required for fan blades to remove ice in different working environments
