| 摘 要： | 针对小型船舶电力推进系统产生的谐波对船舶电网电能质量的影响,建立了谐波分析模型,研究变频驱动产生的输入侧电流谐波在不同工作状态下谐波分布情况,并分析了电力推进系统的动、静态特性对系统产生谐波分布的影响,研究结果表明,谐波电流的大小主要由负载的大小决定,在特殊工况下,系统频率的变化及系统阻抗的变化对谐波分布产生较大影响.

| Abstract: | Aiming to the ship power harmonic pollution which caused by the convertor harmonic current, a simulation model of frequency - variable speed - adjustable system with simple and enough precise is established. The harmonic distribution of input current caused by the convertor was researched in different operation situations. The influence of the dynamic and static feature of etectric propulsion system on the harmonic content of input current was analyzed. It was the foundation for harmonic suppression of electric propulsion system. |
