Judging whether the wind generating set is in a power generation state, if so, indicating that the wind generating set is running, and therefore, when the thickness of ice cubes exceeds a thickness threshold value, timely controlling a heater to heat fan blades so as to melt the ice cubes, thereby achieving a deicing effect; if the wind generating set is not in the power generation state, the wind generating set is not operated, whether a starting time node exists or not is needed to be judged for further judging whether the fan blade can be heated by the heater, if yes, the time for fixedly starting the wind generating set is indicated, therefore, the time difference between the starting time node and the current time node is obtained, whether the time difference exceeds a preset time threshold value is judged, if not, the time difference is indicated to be close to the starting time node, and therefore the heater can be directly started to heat the fan blade, ice cakes are melted, and accordingly deicing effect is achieved, and adverse effects caused by icing of the fan blade are reduced.
According to the fan blade deicing method provided by the embodiment, whether ice cubes exist on the fan blade or not is judged, if the ice cubes do not exist, the fan blade is indicated to be not frozen, therefore, whether an anti-icing coating exists on the Panu single fan blade or not is judged, if the anti-icing coating does not exist, alarm information is generated to remind a worker of setting the anti-icing coating, if the anti-icing coating exists, whether the anti-icing coating meets the preset coating requirement is further judged, and if the anti-icing coating does not meet the preset coating requirement, the anti-icing coating needs to be repaired.
If ice cubes exist, the fan blades are indicated to be frozen, so that whether the thickness of the ice cubes exceeds a thickness threshold value is judged, if the thickness of the ice cubes exceeds the thickness threshold value, the ice cubes are indicated to be thicker, serious influence can be caused if the ice cubes are not timely processed, the heater is controlled to heat the fan blades, the ice cubes are melted, the deicing effect is achieved, whether the current temperature of the fan blades is greater than a preset temperature threshold value is further judged, if the current temperature of the fan blades is greater than the preset temperature threshold value, the deicing effect is judged to be achieved, and the heating of the fan blades is stopped.
The anti-icing coating is arranged, so that the adhesiveness of water vapor on the fan blade is reduced, the water vapor is not easy to adhere to the fan blade, the possibility of icing is reduced, and the heater is arranged, so that ice cubes attached to the fan blade are melted, and the ice cubes are eliminated; by combining the two modes, ice cubes on the fan blade are further eliminated, and adverse effects caused by icing of the fan blade are reduced.
Referring to fig. 2, in one implementation manner of the present embodiment, if an anti-icing coating exists on the fan blade in step S104, the specific steps of determining whether the anti-icing coating meets the preset coating requirement include steps S201 to S207:
step S201: and if the anti-icing coating exists on the fan blade, acquiring the coverage degree of the anti-icing coating.
Specifically, in this embodiment, the coverage degree is the ratio of the area of the surface of the fan blade where the anti-icing coating exists to the surface area of the fan blade.
Step S202: and judging whether the coverage degree exceeds a preset degree threshold value.
Specifically, in this embodiment, the preset degree threshold, that is, the preset minimum allowed coverage degree, and the coverage degree is lower than the preset degree threshold, which indicates that the coverage degree is insufficient.
Step S203: and if the coverage degree does not exceed the preset degree threshold, judging that the anti-icing coating does not meet the preset coating requirement.
Step S204: and if the coverage degree exceeds a preset degree threshold, acquiring the coverage position of the anti-icing coating and the key icing area corresponding to the fan blade.
Specifically, the covering position is the position of the fan blade corresponding to the anti-icing coating, in this embodiment, the fan blade may be divided into three parts of a blade tip, a blade middle part and a blade root, if the blade tip part is covered with the anti-icing coating, the covering position is the blade tip part, and if the blade tip, the blade middle part and the blade root are covered with the anti-icing coating, the covering position is the blade tip, the blade middle part and the blade root; the key icing area is an area with a large icing frequency and a large icing range determined according to actual conditions, and in the embodiment, the key icing area can be a blade tip part.
Step S205: judging whether the covering position completely contains the key icing region.
Step S206: and if the covering position does not completely contain the key icing region, judging that the anti-icing coating does not meet the preset coating requirement.
Step S207: and if the covering position completely comprises the key icing region, judging that the anti-icing coating meets the preset coating requirement.
According to the deicing method for the fan blade, if the anti-icing coating exists on the fan blade, the coverage degree of the anti-icing coating needs to be obtained, whether the coverage degree exceeds the preset degree threshold value is judged, if the coverage degree does not exceed the preset degree threshold value, the fact that the coverage degree of the anti-icing coating on the fan blade does not reach the standard of the normal range is indicated, and therefore it is judged that the anti-icing coating does not meet the preset coating requirement.
If the critical icing area is completely contained, the critical icing area on the fan blade is protected by the anti-icing coating, so that the anti-icing coating is judged to meet the preset coating requirement.
Whether the anti-icing coating meets the preset coating requirement is judged by setting multiple judging conditions, so that the anti-icing coating is repaired according to a judging result, and the possibility of icing of the fan blade caused by the fact that the anti-icing coating does not meet the preset coating requirement is reduced.

step S301: and if the current temperature is greater than the preset temperature threshold, acquiring environmental factors.
Specifically, in this embodiment, the environmental factors, that is, the environmental factors of the area where the fan blade is located, include wind conditions, air temperature conditions, air humidity conditions, and the like.
Step S302: based on environmental factors, air temperature and air humidity are obtained.
Specifically, in this embodiment, the air temperature is the air humidity of the area where the fan blade is located, and the air temperature is the air temperature of the area where the fan blade is located.
Step S303: judging whether the air temperature and the air humidity meet the preset environmental requirements.

Step S304: if the air temperature and the air humidity meet the preset environmental requirements, the fan blade is kept to be heated.
Specifically, in this embodiment, if the air temperature and the air humidity both meet the preset environmental requirements, it indicates that the current environmental factor meets the icing condition, so as to prevent the fan blade from continuously icing, so that the fan blade is kept heated, so that the surface temperature of the fan blade is increased, and the fan blade cannot be iced.
Step S305: and if the air temperature and/or the air humidity do not meet the preset environmental requirements, stopping heating the fan blade.
Specifically, in this embodiment, as long as more than one condition is not satisfied, that is, the air temperature does not satisfy the temperature requirement but the air humidity satisfies the humidity requirement, or the air humidity does not satisfy the humidity requirement but the air temperature satisfies the temperature requirement, or the air humidity satisfies the humidity requirement and the air humidity does not satisfy the humidity requirement, all the conditions do not satisfy the preset environmental requirement, so that the icing condition cannot be achieved, so that the fan blade does not need to be heated continuously through the heater, thereby contributing to reducing the energy loss.
According to the fan blade deicing method, the air temperature and the air humidity are obtained, whether the air temperature and the air humidity meet preset environmental requirements is judged, if yes, the fact that even if the fan blade is deicing is indicated, according to the air temperature and the air humidity, icing can still occur soon, and therefore the fan blade is kept to be heated, the surface of the fan blade is always at a higher temperature, the fan blade is not frozen in a certain time range, adverse effects caused by the fan blade icing are reduced, if at least one of the fan blade does not meet preset environmental requirements, the fact that icing conditions are not met in a next period of time is indicated, continuous heating of the fan blade is not needed, heating is stopped in time, and energy consumption is reduced.
Whether the air temperature and the air humidity meet preset environmental requirements or not is judged, so that whether the fan blade still can freeze in a period of time is judged, and according to a judging result, the fan blade is prevented from continuing to freeze in a period of time, adverse effects caused by the icing of the fan are reduced, and energy loss caused by heating the fan blade for a long time is reduced.

Specifically, in this embodiment, if the energy consumption difference exceeds the preset energy threshold, it indicates that the energy consumption difference is too large, that is, the second energy consumption corresponding to continuous heating is far greater than the first energy consumption corresponding to single deicing, so that to reduce the energy consumption, the heating of the fan blade is stopped, that is, the fan blade is selected to be deicing by means of single deicing.
Step S406: if the energy consumption difference value does not exceed the preset energy threshold value, the fan blade is kept heated.
According to the fan blade deicing method provided by the embodiment, according to the first energy consumption corresponding to single deicing and the second energy consumption corresponding to continuous heating, the energy consumption difference is obtained, whether the energy consumption difference exceeds a preset energy threshold value is judged, if yes, the energy consumed by continuous heating deicing is far more than that consumed by single intermittent heating deicing, and therefore the fan blade is stopped being heated, so that the energy consumption is reduced; if the energy consumption of continuous heating deicing is less than or slightly more than the energy consumption of single intermittent heating deicing, the fan blade is heated, so that the fan blade is not frozen for a certain time, and adverse effects caused by fan icing are reduced.
