Good morning! I have a few questions about wind energy. I'm currently reading about wind energy

Personal understanding: 1. Wind power generation uncertainty refers to the uncertainty of the wind power utilization rate of the wind farm throughout the year. The time spent on normal maintenance and shutdown of wind turbines is uncertain each year, so the duration of wind energy use of wind turbines throughout the year is uncertain and the amount of electricity produced is uncertain.

2. When selecting a location for a wind power plant, select the location where the wind turbine will be erected. After at least two to four years of accumulating crosswind data in the selected area, use the wind turbine site. selection software to make the selection. After the selection, the wind farm will be completed for at least It will take another two years. During this period, environmental change factors cannot be predicted, so it is also the uncertainty of thehe production of wind energy.

This is my own understanding. . . See if it works·

The theoretical energy production calculated by the wind energy software should be corrected as follows according to the degree of influencing factors.

1) Air density reduction, the calculation formula of air density reduction coefficient is: air density reduction coefficient = (1 - wind field air density / standard air density) * before the rated wind speed Wind energy frequency.

If the on-site air density power curve is used to calculate electricity production, there is no need to reduce it.

2) Reduction of wake losses The wake losses of each wind turbine are generally taken into account by software calculations, so the reductions will not be repeated.

3) The utilization rate of wind turbines depends on the fact that the windiennes are out of service or repaired, then from the network.

Organize Tangfeng Songxiu in Xiaofengyue. Based on the current manufacturing level of wind turbines and the actual situation of the wind farm, the utilization rate of wind turbines is estimated to be around 95%.
