Wind turbines rely on wind energy to run the generator and produce electricity. When the wind speed is high, the wind turbine will be larger and produce more electricity. However, there should be voltage limiting equipment to prevent it from doing so. impacting the national network. Therefore, when the wind speed is high, the electricity generation will be high.
I hope this can help you and wish you happiness every day!

P50 power generation means it can reach 50% of wind power generation.
Since electricity production is directly linked to the investment income of wind power plants, the assessment of electricity production is subject to due diligence. Wind resource assessment is the most basic, which is equivalent to macro-assessment of wind power plantsnnes. Through the assessment of wind resources we will obtain a calculation of the theoretical energy production and the probability of achieving a certain electricity production. This is usually called P50 and P75. The probability of achieving this electricity production is 50% or 75%. This gives us a standard for evaluating electricity production during an investment.
1. The power output of type A unit consists of three parts of time.
The power output is zero when the wind speed is less than 3, and the power output is zero when the wind speed is not less than 3 meters/second, a total of approximately 160 days. Electricity production is
2. Suppose the type A generator is 1) -X is fed into (2) (3) to get 1.7＜X＜6 Y＞4
Everyone knows this if you buy two things with different prices, and the total quantity is certain, plus the thing is expensive The less the better, that is, the less X the better, and X should be at least 2, so Y is 8, which just fits the conditions. So the most economical solution is 2 units of type A and 8 units of type B
This question is so embarrassing, but I answered it so well. Brother, you don't want to add points, haha.
