Maximum power production occurs when the wind turbine angle is 90 degrees. Through investigations, we learned that when wind blows on fans side by side at different angles, the power output changes. When the angle is 90 degrees, that is, when the wind direction deviates by 10 to 15 degrees, the electricity production is the highest. Therefore, the power generation efficiency of the wind turbine array is best when it deviates slightly from the main wind direction.
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 usage 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 wind power generation.
