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。
If one set stops and reverse power protection is not provided, the set still running will drive the set that has stopped. The generator on the set that has stopped will act as a motor.
如果一台发电机组没有运转，并且没有逆功率继电器保护，运转的机组就会驱动这个机组，这台机组上的发电机则变成电动机运行。
