为了优化风力涡轮机的运行，需要可变的涡轮机转速。为了确定变速涡轮机的优势，需要考虑涡轮机的年化发电量。这是通过使用瑞利概率分布来确定特定风速在给定年份发生的小时数来实现的。这一分布与在给定平均风速下产生的空气动力功率一起使用，以确定一年中产生的总能量。对定速和变速汽轮机控制的总能量进行了比较。与恒速系统相比，变速涡轮机显示出更高的能效。
To optimize the operation of a wind turbine, variable turbine speeds are desirable. To determine the advantages of a variable speed turbine, the annualized energy production of the turbine needs to be considered. This is done by using a Rayleigh probability distribution to determine the number of hours of a particular wind speed occurs in a given year. This distribution is used with the aerodynamic power generated at a given average wind speed to determine the total energy generated during the year. The total energy for fixed and variable speed turbine control are compared. The variable speed turbines show improved energy production over the constant speed systems.
