Problems solved by technology

The device judges whether it is icing by detecting the temperature of the blade surface. This method cannot completely judge whether the fan blades are icing under low temperature conditions in areas with less water in the air, and it also uses heating to deicing, which consumes energy. Big

Abstract

The invention discloses an automatic anti-icing deicing system and an anti-icing deicing method for a fan blade. The automatic anti-icing deicing system for the fan blade comprises an icing analytic unit, a standing wave deicing unit, a traveling wave anti-icing unit, a vibration frequency sensing unit and a control unit, wherein the icing analytic unit, the standing wave deicing unit, the traveling wave anti-icing unit and the vibration frequency sensing unit are arranged in the fan blade, and the icing analytic unit, the standing wave deicing unit, the traveling wave anti-icing unit and the vibration frequency sensing unit are respectively connected with the control unit. The automatic anti-icing deicing system and the anti-icing deicing method for the fan blade have the advantages that icing condition of the fan blade can be rapidly and accurately determined; further ice blocks on the fan blade can be timely and automatically removed; and anti-icing treatment can be automatically carried out, so that serious icing on the fan blade is prevented, and normal operation of a fan is guaranteed.

Description

Technical field [0001] The invention relates to an automatic anti-icing and deicing system for fan blades and an anti-icing and deicing method. Background technique [0002] Wind turbines are generally installed in wet and cold areas such as mountains and borders with abundant wind resources. The problem of blade icing has become one of the serious hidden dangers affecting its safe operation. Wind turbine blade icing leads to the change of blade aerodynamic shape is one of the main factors affecting the safety and reliability of wind turbines. When the blades are heavily iced, the efficiency of the wind turbine is reduced, and the output power of the turbine is reduced, which may cause unplanned shutdown of the wind turbine and affect the grid Safe and stable operation of the system. Severe icing will also cause blade breakage and unit damage. At the same time, the ice layer will fall off in the rotating state, which can easily cause operational accidents. According to statisti...
