That is, when the motor (1) has a driving torque fluctuation caused by torsional vibration in the crankshaft system like a diesel engine, the fluctuation is transmitted to the generator (2), and the driving torque in the rotor section of the generator (2) is transmitted. The fluctuations are extremely large,
Electric power fluctuations and voltage fluctuations occur in the generator (2), and the quality of supplied electricity decreases. Therefore, when designing the power generator, it is necessary to carefully study the entire shaft system of the diesel engine and the generator, and design the shaft system with the least drive torque fluctuation. However, depending on the basic conditions of the power generator, it may not be possible to set a shaft system that reduces drive torque fluctuations to an appropriate level. In this case, the drive of the rotor of the generator (2) is performed as described above. The torque fluctuation becomes extremely large, and power and voltage fluctuations occur in the generator (2).
The quality of the electricity supplied is reduced. Also, the frame vibration of the prime mover (1) needs to be sufficiently reduced from the viewpoint of improving the reliability and durability of the power generator.
