求翻译：风电机组的原动力来源于流经风机的风能，风机的输出功率主要决定于风速、空气密度等，而风速是一个不稳定的变量，即风速在一个较短的时间段内可能出现大的变化，并且这种变化是间歇性的、不规则的，这就导致风机的输出功率将产生快速波动。是什么意思？

The driving force behind the wind turbine from the wind flowing through the fan, the fan output power is mainly determined by wind speed, air density, and wind speed is a volatile variable, that is wind speed in a short period of time may be a big change , and this change is intermittent, irregular,

Wind power generating units were the driving force behind the source flows through wind machine in the wind, the wind machine output power mainly determined by the wind speed, density, and so on, and wind speed is an unstable variables, i.e. , wind speed over a relatively short period of time might

The wind electrical machinery driving force originates from the class after the air blower wind energy, the air blower output mainly decides in the wind speed, the air density and so on, but the wind speed is a unstable variable, namely the wind speed possibly appears the big change in a short time

Wind turbine motive power comes from the wind flows through the fan, fan output power mainly depends on wind speed, air density, and wind speed is a volatile variable, namely wind speed over a big change can occur within a short period of time, and this variation is intermittent, irregular, which le

The driving force behind the wind turbine from the wind flowing through the fan, the fan output power is mainly determined by wind speed, air density, and wind speed is a volatile variable, that is wind speed in a short period of time may be a big change , and this change is intermittent, irregular,
