Problems solved by technology

[0004] However, due to the large space in the blade cavity and the low heat conduction efficiency of the air, the heating efficiency of the heater used in the prior art to heat the air in the blade cavity is low, and the heating output power is likely to be high, but The deicing effect is not good, and sometimes even the local temperature is too high, resulting in damage to the blades

Abstract

The invention provides a heating control system and method for a blade of a wind power generating set. The heating control system comprises a heating unit, a temperature collecting unit and a controlunit. The heating unit is arranged at the blade root baffle position of the blade. Hot air is output according to power of the heating unit. A hot air outlet of the heating unit extends into a mold cavity of the blade. The temperature collecting unit includes a temperature sensor arranged at the hot air outlet, the temperature sensor is used for measuring a temperature controller at the hot air outlet, and the temperature controller is used for controlling the heating unit to be started when the blade surface is frozen to updating the power of the heating unit according to the temperature of the hot air outlet. By adopting the technical scheme in the embodiment of the invention, the good deicing effect can be achieved under the precondition of improving the heating efficiency.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a blade heating control system and method of a wind power generating set. Background technique [0002] At present, wind power has become the main force of new energy generation in my country. Wind turbines are usually installed in areas rich in wind energy resources such as plateaus, cold regions, ridges or mountain tops. However, these areas have low winter temperatures and are prone to ice formation on the surface of leaves. Since icing on the surface of the blades will overload the blades and reduce the service life of the connecting parts of the blades, it is necessary to remove the icing on the surface of the blades in time during the operation of the wind turbine in a low-temperature environment. [0003] In order to clear the ice on the surface of the blade in time, the method in the prior art uses a heater to heat the air in the cavity of the blade to ind...
