In addition, the output frequency of a motor generator set shall not vary by more than 5% when operated at rated output voltage and current.

另外，当发电机以额定电压啊，电流运行时，其出力(输出功率)频率允许在上下5%内跳动。

Wind turbine generators have the biggest influence on grid frequency when the generators trip and exit the power grid at rated active output power.

当风力发电机组在额定输出有功功率跳闸退出电网时，对电网频率的影响最大；
