The lower balance force with balance factor 0.89 is adapted to reduce bending of universal coupling shaft and load of copper slider.
提出接轴平衡力应该采用欠平衡，平衡系数取0.89，这样既可以降低接轴承受的弯矩，又可以降低接轴虎口铜滑块的载荷。
The voltage between the system and generator must be small enough to ensure minor current in the armature winding of generator, avoiding the impact to the coupling shaft.
发电机电压与系统电压之差必须足够小，避免合闸时发电机电枢绕组电流过大，对发电机联轴系统产生冲击。
The phase and frequency between the system and generator must be small enough to ensure minor current in the armature winding of generator, avoiding the impact to the coupling shaft.
避免由于压差、频差和相角差太大，使的合闸时，发电机组电枢绕组电流过大，对发电机组联轴系统产生冲击。
