Blade de-icing device and method for a wind power plant

Abstract

The invention relates to blade ice removing equipment and a blade ice removing method applied to a wind generating set. The blade ice removing equipment comprises an ice removing unit, a temperature detecting unit and an embedded type control unit, wherein the ice removing unit is used for removing ice from each blade; the temperature detecting unit is used for detecting the temperature of each blade; and the embedded type control unit is used for determining whether to control the ice removing unit to implement ice removal operation or not according to a received freezing signal from an external device and determining whether to control the ice removing unit to stop the ice removal operation or not according to a detected temperature value detected by the temperature detecting unit.

Description

technical field [0001] The invention relates to the technical field of wind power generation, and more specifically, to a blade deicing device and method for a wind power generating set. Background technique [0002] In view of the negative impact of fossil fuel consumption on the ecological environment, renewable energy has attracted much attention in recent years, and it is the general trend to replace traditional energy with new clean energy. Due to the short construction period and high power generation efficiency of wind turbines, they are more and more popular, so wind power has become the main force of new energy power generation in my country. In addition, the development and utilization of renewable clean energy resources such as wind energy is in line with the trajectory of energy development and plays a major role in establishing a sustainable energy system, promoting national economic development and environmental protection. [0003] However, some areas (for ex...

Problems solved by technology

[0003] However, some areas (e.g., mountain tops, plateaus, cold regions, etc.) have excellent wind resources, but due to the low temperature and high humidity in these areas in winter, they are prone to freezing

The icing of the blades will cause the deterioration of the aerodynamic performance of the blades of the wind turbine, the overload of the blades and the uneven distribution of the blade load, which will lead to the decrease of the wind capture capacity of the blades of the wind turbine and affect the power generation, and the overload of the blades and the uneven distribution of the blade load will also cause problems. Reduced component life

In addition, during the rotation of the blades, when the adhesion of the ice layer decreases, it is very easy for the ice to fall off, which may easily cause operational accidents.

[0004] At present, the icing of wind turbine blades has become an important factor hindering the development of wind energy, and it is also an uncertain factor in the construction of wind farms, which greatly reduces the utilization rate of wind turbines and seriously threatens the safe operation of wind turbines. a potential hazard
