Description
Technical Field
The invention belongs to the technical field of wind power generation, and particularly relates to a wind power blade deicing system and method based on an unmanned aerial vehicle.
Background
With the increasing global environmental problems and energy crisis, clean energy is more and more valued by various countries. The wind energy as a renewable energy source has huge storage amount, wide distribution range and great development and utilization potential.
The working environment of the wind generating set is outdoors with rich wind power resources, and in some wind fields with high environment humidity, large precipitation and low temperature, when the temperature drops below zero centigrade, the blades of the wind generating set can be frozen, ice adheres to the blades, the wing profiles of the blades are changed, the pneumatic performance of the blades is influenced, the generating efficiency of the wind generating set is reduced, the dynamic and static loads of the whole wind generating set are increased, and the integral strength and stability are more adversely affected. Therefore, the method can prevent and timely remove the icing on the fan blade, and has very important significance for ensuring the normal and efficient operation of the wind driven generator device.
Currently common blade anti-icing/de-icing techniques include: thermal de-icing, mechanical de-icing, liquid de-icing, etc. Thermal deicing usually adopts a mode that a cavity is arranged inside and hot solution is introduced, and resistance wires are arranged inside blades. The mode of arranging the cavity in the blade can cause stress concentration of the wind power blade, and the mode cannot completely remove the ice layer of the blade; the mode that the resistance wire is arranged inside the blade is complex in process and high in cost, and the heating performance of the resistance wire cannot be guaranteed. The thermal deicing technology has the disadvantages of relatively high energy consumption, additional introduction of a heater for consuming electric energy and reduction of the wind power generation efficiency. Mechanical deicing is to break an ice layer by a mechanical method, and then the broken ice is impacted on the surface of a blade by airflow to slide down, or the ice layer is removed by utilizing the centrifugal force when the blade rotates or the slight vibration of the blade. However, this method requires a fixed installation on each blade at the beginning of the construction of the wind turbine generator system, which results in a difficult maintenance of the equipment after a long period of use and a risk of breaking the tooth root during a long period of operation. The liquid deicing is mainly to spray deicing liquid on the surface of the blade so as to reduce the freezing point of the surface of the wind power blade or change the adhesive force between the surface of the blade and an ice layer, but the existing deicing liquid can cause secondary pollution to the environment, corrode the surface coating of the blade and cannot be sprayed on the surface of the blade in a large area. Therefore, how to provide a method which is convenient to operate, flexible to use, low in cost, free of corrosion influence on the wind power blade, free of secondary pollution to the surrounding environment and high in deicing efficiency is a problem to be solved urgently in the technical field of deicing of the wind power blade.
