Icing on wind turbines, ranging from energy losses to mechanical and electrical failures security risks This situation causes the turbines to performance And efficiency while negatively affecting, increases operating costs

Anti-icing (Anti-Icing) And defrost (De-Icing) solutions to minimize these risks and create economical, reliable systems. an effective solution presents.

Well, rapidly developing Drone technology How is it integrated into these strategies? In this article, we will discuss the benefits of drone technology its innovative role in wind turbine icing prevention and de-icing methods we will discover together.

Why Does Icing Occur on Wind Turbines?

Operating a wind farm is much more than just determining where to place the turbines and planning the wind speed and frequency at the site. It is complicated

Various resources, for wind turbines suitable areas, small turbines annual average wind speed of at least 9 miles per hour (mph) — or 4.0 meters per second (m/s) — and large scale turbines indicates that there are areas where the wind speed is 13 mph (5.8 m/s).

Straight And summits of round hillswater surfaces And wind-driven And accelerating mountain passes, is among the ideal areas for wind turbines. Wind speed above the ground surface increasing as it rises Large wind turbines typically range in height from 500 feet (about 152 meters) to 900 feet (about 274 meters) placed on towers with a height of.

Science Direct According to the data, in regions with northern climates Due to the increased air density caused by lower temperatures, available wind energy is lower than in other regions. yaklaşık %10 daha fazladır.

For the first 1000 meters, as altitude increases, wind speed increases by 0.1 m/s for every 100 meters, makes high altitudes ideal areas for wind turbines. However, although higher altitudes provide better efficiency, they also brings with it the risk of icing.

Power plants built in the world's most efficient wind areas continue to find effective solutions to the icing problem. most remarkable And innovator One of the methods that has attracted great attention in recent years is drone technology. Before moving on to drone technology, we should consider the effects of icing on wind turbines. problems Let's examine.

What are the Effects of Icing on Wind Turbines?

What are the Effects of Icing on Wind Turbines-

Icing on wind turbines three different Icing, which is divided into in-cloud, precipitation-induced icing and frost, depends on various causes.

  • Intracloud Icing: It occurs when superfrozen water droplets freeze on impact with a surface below 0 °C.
  • Precipitation-Induced Icing: May be caused by snow and rain. May cause more damage than intra-cloud icing.
  • Frost: It is usually formed by the solidification of water vapor on a cold surface during low wind conditions.

The damage caused to wind turbines by these three different types of icing is both wind assessment phase as well as the operating process of wind power plants may affect. 

Wind Measurement Errors

Icing in wind turbines, wind speed ölçüm hatalarını %30’a kadar çıkarabilir. (2) To measure wind speed during the evaluation phase of wind turbines Anemometers, to determine wind direction directional valves and to measure the temperature value of the air temperature sensors is used.

In icy conditions, ice accumulates on these devices, restricts the movements of devices or stops completelyFor example, if ice accumulates on the rotating parts of the anemometer, the device will not work properly. can't return And may measure inaccurate wind speeds.

As a result, due to icing, incorrect data provided by measuring devices may lead to inaccurate information on where to install wind turbines. wrong decisions For example, an area thought to have low wind speed may actually have a suitable speed, but measurement errors may conceal this fact.

Energy Losses

Icing in wind turbines causes energy losses negatively affects power plant performance. The blades of wind turbines have a special shape to best direct the air flow and optimize energy production. aerodynamic profile This profile allows the wings to obtain maximum energy from the wind. Ice accumulated on the wing surface disrupts this aerodynamic profile.

For example, the wings move with the wind first contact formed on the leading edge Even small amounts of ice seriously affect aerodynamic properties. Although the amount of ice on the wings may seem small, its effect can be quite large. At the initial point of contact, ice forms as the air moves along the wing disrupts the smooth flow.More wings reduces buoyancy and this too reduces energy production.

Mechanical Failures

Icing in wind turbines increases the load on both the blades and the tower structure. creates mass imbalance.

  • Weight of ice accumulation; makes it difficult for the wings to rotate and creates extra load on the tower and wing connections.
  • Ice accumulates irregularly on the wings; creates imbalance. This may lead to cracks, breaks or premature wear in the structural elements of the turbine.
  • Icing; created to ensure the smooth operation of mechanical components causes damage to lubrication systemsThis causes the moving parts to rub against each other more and the system to work more difficultly.

Mechanical failures increase the maintenance and repair costs of turbines, as well as turbine stoppage or reduced capacity leads to.

Security Risks

Icing in wind turbines poses various risks to both the environment and humans. security risks For example, the accumulation on the wings large ice floes, while the wings are rotating, they separate from the wings and spread to the environment jettisonable. Due to the ice blocks thrown into the surrounding area, people, vehicles or structures may be damaged.

Monte-Carlo Simulation; This simulation is performed in a field that is icy for 5 days a year. The probability of a person walking under the turbine for 10 hours being hit by a piece of ice between 0.18 and 0.36 kg It is 1/10. This, This means that 1 in 10 people could be exposed to this risk.. (1)

As a result, icing on wind turbines is a domino by creating an effect only operational inefficiency but also for people and the environment serious security problems also leads to.

To avoid such problemsn anti-icing (Anti-Icing) And defrost (De-Icingsolutions can be used effectively.

Anti-Icing and De-Icing Solutions in Wind Turbines

Anti-Icing and De-Icing solutions are used to remove ice in wind turbines. Common points de-icing Even though they develop different solutions within themselves.

An important point here is that during the De-icing process, the turbine can be manually or automatically to be stopped Once the blades are completely free of ice, the wind turbines involved can be put back into operation.
