2022 is really an eventful year. Not only is the epidemic raging, but wind power accidents are also emerging one after another.
As a renewable and clean energy, wind energy has incomparable advantages over traditional energy, and is therefore increasingly attracting widespread attention from countries around the world. With the rapid development of the wind power industry, the reliability of wind turbine operation has become prominent, and safety accidents have occurred frequently, especially fire accidents. What are the causes? What do you think is the cause of wind power accidents? Who should be held responsible? ,,
On October 26, 2022, another wind turbine fire occurred! And it caused a ground wildfire!
The accident occurred in Iowa, a central state in the United States.
A wind turbine in the small town of Williamsburg in the central U.S. state of Iowa suddenly caught fire, and the falling burning debris even caused a small fire on the ground.
According to local media reports, the Williamsburg Fire Department was dispatched to the 1700 block of 230th Street at around 0:40 a.m. Monday. When the staff arrived at the scene, the wind turbine's cabin was completely engulfed in flames. The Williamsburg Fire Department told the media that dealing with a towering wind turbine fire is extremely challenging because there are many factors to consider. Including falling flaming debris and the danger of wind turbine blades and devices falling at any time. Faced with such a situation, the staff protected the scene at the fastest speed to ensure the safety of everyone in the area. At the same time, the fire department extinguished the wildfire on the ground.
2022.10.14 Be alert! A wind turbine suddenly caught fire in a small town in northern Germany!
On October 14 (local time Friday night), the German Northern Messenger TV (NordkurierTV) broadcast a video of a wind turbine on fire.
It is reported that the location of the wind turbine fire accident is located in Rbel/Müritz, a small town in Mecklenburg-Vorpommern on the west coast of northern Germany.
Location of the fan fire accident
On Friday evening, a wind turbine caught fire at a wind farm between the towns of Jaebetz and Freyenstein near the border of Mecklenburg-Vorpommern and Brandenburg.
The fire could not be put out from the ground - the fire brigade that received the alarm at around 5:30 pm could only watch the wind turbine burn. However, as the burning parts kept falling to the ground, it protected the fire scene from a large area.
The fire at the wind turbine, which has a hub height of about 60 meters, continued until late at night.
2022.7.22 Breaking news! A wind turbine fire occurred at a 30MW wind farm
On the afternoon of July 22, a wind turbine at the Ardrossan wind farm in Scotland, UK, caught fire. Thick black smoke instantly enveloped the sky, and the fire was not extinguished until early Saturday morning. Fortunately, the accident did not cause any casualties.
It is understood that the Ardrossan wind farm started operation in 2004 and was acquired by Ventient Energy from Infinis in 2017. The wind farm has a construction scale of 30MW. The wind farm is equipped with 15 Vestas V80-2.0MW wind turbines, each with a height of 60 meters and a single unit capacity of 2MW.
A Ventient Energy spokesman said: "Investigations into the cause of the incident are ongoing".
This is not the first time that a fan fire has occurred.
At 1:00 pm local time on October 19, an offshore wind turbine off the coast of Arklow, Ireland, was struck by lightning and caught fire. It is understood that the offshore wind farm where the burning wind turbine is located has a total of 7 operating units, and the burning wind turbine is one of them. The wind farm has been in operation for more than 20 years and is operated by GE Energy.
This is a distant view of the fan fire video:
The city where the accident occurred is Arklow
According to local media reports, the orange thunderstorm warning for the four local counties and cities lasted until 11 pm before the accident. Dublin, Wexford, Wicklow, Waterford and other places will experience thunderstorms, and local flooding may occur.
The fire fan is expected to burn out without emergency service intervention.
Thick smoke billowed from the wind turbine after it was struck by lightning in the afternoon local time. Standard industry practice for unmanned wind turbines is to allow the fire to burn out on its own.
2022.7.11
On July 11, a wind turbine fire occurred in Nanyang City, Henan Province, and the unit was damaged. The model and project information of the accident were unknown.
On June 24, 2022, the National Energy Administration reported a wind turbine fire accident on May 6!
On June 24, the Southern Energy Regulatory Bureau issued a notice on a wind turbine fire incident at a wind farm in Hainan, stating:
On May 6, a fire occurred at a wind farm in Hainan. The performance of the lightning arrester on the high-voltage side of the box-type transformer deteriorated. During the power supply and operation recovery process of the wind turbine, the lightning arrester broke down, causing the wind turbine transformer to catch fire, resulting in the burning of the transformer and some electrical equipment.
International Energy Analysis:
Thunderstorms are considered one of the most deadly threats to wind farms. Metal shells and high altitudes make them very vulnerable to lightning strikes. However, the frequency of lightning strikes in Europe is much lower than that in my country, and the wind farm was built 20 years ago, so the wind turbines are not well protected against lightning strikes.
my country is a latecomer in offshore wind power construction, and the frequency of lightning in East Asia where my country is located is much higher and the natural environment is more severe than in Europe. Therefore, both onshore and offshore units have been designed with consideration of performance to protect against lightning strikes.
By analyzing the defects of the original lightning protection system, studying the characteristics of lightning damage to blades and the principle of lightning protection, and installing lightning guide strips on the surface of the blades, the lightning protection range of the blades can be effectively increased, which can reduce the proportion of blade damage caused by lightning strikes.
What do you think about so many fan fire accidents?
