Do you want to ask how long it takes to hoist wind turbines into onshore wind power plants? 3 days.
The whole process of lifting a wind turbine includes several steps such as preparation, blade lifting, main head lifting, generator lifting, lifting tower and Electrical Installation. Among them, blade lifting and main head lifting are the most time-consuming steps. It takes 3 days to hoist a single wind turbine. In addition, the lifting of wind turbines is also affected by many factors such as weather, geographical location, equipment model, etc., so the exact lifting time cannot be given.
How many kilowatt hours of electricity does a 70 meter blade spin? Currently, China is actively developing new energy sources. Wind energy is one of the most important aspects. It mainly uses eo energylink to drive blades to produce electricity. Do you know how many kilowatt hours of electricity a wind turbine blade generates?
When it comes to wind power generation, many people find it interesting. We all know that every wind power generator is equipped with three fan blades. It looks like a large windmill and has a strange shape. These fan blades don't spin very quickly, so some people think it only takes one turn. the electricity produced is very small, so do you know how much electricity these large wind turbines can produce when they rotate once?
If you want to know how many kilowatt hours of electricity these blades can produce when they rotate once, you first need to find out the power of these generators, ranging from hundreds of watts to one of thousands of watts, there are also several kilowatts, and there are alsotens of thousands of watts, so specific problems need to be analyzed in detail. Generally speaking, the rotation period of these low-power generators is relatively long, so the current generated by each rotation is relatively small.
According to the different rotation axes of wind power generators, wind power generators are divided into horizontal axis wind turbines and vertical axis wind turbines. The principle of wind power generation is actually very simple. Blowing the wind turbine generates kinetic energy, which is then converted into electrical energy by an internal generator. Depending on the power of the wind power generator, the amount of electrical energy generated by the wind power generator varies each time. For example, the most common 2MW direct drive wind power generator can produce electricity every 60 minutes when the wind power ist sufficient. and stable. It generates 2000 degrees of electricity, and it takes 3.5 seconds for the fan blades to rotate once. 60 minutes corresponds to 3600 seconds. Therefore, the electricity generated by the generator is 0.56 degrees. electricity per turn. The power is 0.56 × 3.5 seconds, or 1.94 kilowatt hours of electricity.
You can calculate that ten kilowatts are generated in one hour, which means ten kilowatt hours of electricity per hour. If it spins for an hour, the electricity generated by each rotation is only a few tenths of a kilowatt. hour. The situation is different for these large generators. Generally, their power is several tens of thousands of watts. The electricity produced per cycle is approximately a little over one degree. For some megawatt generators, it is even larger. related to factors such as fan type and capacity and generator speed.
