Does the questioner want to ask about “why the wind turbines caught fire”? Fires caused by lightning and electrical short circuits.
1. Lightning-Initiated Fires: A large amount of fire data shows that lightning strikes are one of the leading causes of fires in wind turbines. The wind turbines are located at an altitude of more than 50 m. there are no lightning protection installations or the installations are poorly maintained. The risk of fire caused by lightning is particularly high.
2. Fire caused by electrical short circuit: An electrical short circuit caused by transformer body failure or pollution flashover. The fire is caused by a ground fault, a short circuit of the circuit and the electricity generated, which causes overloading of the components and subsequent overheating.
The cPipeline corrosion caused by wind power generation
is proportional to the cube.
1. The most critical factor in wind power generation is wind size, and wind conditions offshore are generally better than on land. Wind speeds at sea 10 kilometers offshore are typically 20% higher than on land. along the coast. The power generated by wind turbines is proportional to the cube of the wind speed, so under the same conditions, the annual power generated by offshore wind turbines can be 70% higher than that produced on land. At the same time, there are rarely periods of calm wind at sea, so wind turbines can produce electricity for longer. Generally speaking, the annual power generation usage time of onshore wind turbines is about 2,000 hours, while that of offshore wind turbines can often reach more than 3,000 hours.
2. For wind power equipment, the land terrain is complex and rugged, and wind speeds at different heights often vary greatly, resulting in wind shear and turbulence, which exerts higher and lower forces on the wind. unbalanced wheel, which can lead to vibration, fatigue and even blade breakage, and the transmission system is also easily damaged. There are few such risks at sea. In addition, offshore wind power is mainly built tens of kilometers from the coast, close to the centers of energy consumption, and there is virtually no risk of abandonment of wind energy.
How to assess weather risks for wind projects and their corresponding financial risk management strategies?
The reasons for pipeline corrosion caused by wind power are:
1. THEs wind farms require deep excavation and construction of the wind turbine tower foundations, which will destroy or change the original soil structure. Causes problems such as changes in groundwater levels and soil erosion, thus accelerating the corrosion of pipelines.
2. Natural water sources such as rain and snow will accumulate around wind farms. These water sources will come into contact with pipelines via groundwater, increasing the risk of pipeline corrosion.
Weather is one of the most important factors in wind energy projects because wind is key to electricity generation. Here are some steps for assessing the weather risks of a wind energy project and developing a financial risk management strategy:
1. Study wind speed data. A comprehensive analysis of wind speed datait be carried out including analysis of historical data as well as model predictions. Understand the impact of different weather phenomena on your data, such as seasonality or topography.
2. Study market demand. Understand what the market demand is for wind power generation and predict future market trends. This makes it possible to assess the risks and impacts of future wind energy production.
3. Develop alternative plans. Develop alternative plans to deal with unexpected situations. For example, developing alternative measures such as wind turbines, energy storage equipment, backup power supplies and grid connections to deal with unusually high or low wind speeds.
4. Define available risk management tools. Develop appropriate risk management tools for risks,including insurance, futures, options and weather derivatives. For example, weather derivatives can help wind companies mitigate financial losses in the event of unexpected events.
5. Manage and monitor risks. Monitoring and risk management of all relevant aspects, including real-time monitoring of wind speed, market conditions, evaluation of alternatives and risk management tools, etc.
In summary, for wind projects, it is important to identify and manage weather-related risks. Only by fully mastering relevant data, formulating reasonable alternative plans and appropriate risk management tools can the long-term success and healthy development of the project be ensured.
