摘　　要：现在广泛使用的船舶轴带发电机系统控制相对简单,但对船舶电网中的电能质量影响大,并且需要依靠同步发电机来补偿无功等缺点。本文在分析了轴带发电机发展历程与工作过程的基础上,介绍一种新型的轴带发电机模式,利用全控型PWM整流器的四象限运行功能,实现有功、无功的快速调节。给出了整个系统的主电路与控制方案,从理论上解释了这种新的轴带发电机系统的正确性和可行性。Although the control of a ship shaft generator widely used is comparatively simple, it has great effect on the quality of ship power, and it needs a synchronous generator to compensate var. By analyzing the development and the principle of traditional system, this paper describes a new shaft generation system. Based on the fully controlled PWM rectifier which can work on four quadrants, it can accommodate active and reactive power quickly. It gives the main circuit and the project of the control, and explains the correctness and feasibility of the new shaft generator system in the theory.
