摘　　要： 随着船舶大型化、多功能化和节能化的发展,对船舶电力系统的要求越来越高。连船并网及船舶解列过程中可能会出现发电机频率及幅值调节不准确的情况,导致逆功率的产生。文中采用全软件方式的智能化逆功率控制方案,能够有效抑制逆功率的产生,提高了整个系统的可靠性,使系统在并脱网及负荷转移过程中可实现能量的双向传递,抑制切换过程中的电流和电压冲击,令船舶供电过程实现无缝平滑的切换。 As ships are getting larger in size and equipped with more multiple functions and energy-saving facilities, the requirements of the ship power system are higher. In the process of connecting ships with the power grid and ship routing, possible inaccurate adjustment of the power generator＇s frequency and amplitude leads to generation of the inverse power. This paper adopts a full-software intelligent scheme to control the reverse power, which can effectively suppress the reverse power and improve the reliability of the whole system so that the system can realize the two-way transfer of energy in the off-grid and load transfer process. The current and voltage surge are suppressed and thus the power supply of ships can be switched smoothly and seamlessly.
