Abstract

In this paper, the characteristics of a marine electric propulsion system are introduced, and the power quality actuality of the system is also interpreted. Then, the significance of improving of improving power quality which are nowadays applied to marine electric propulsion systems are analyzed. Finally, a new approach - the combination of active power factor compensator and series active filter aided by parallel passive filter - is proposed for marine electric propulsion system. According to the working principles of the aforementioned new approach, it can be predicted that the combined system seems to be promising to compensate for harmonics and promote power factor in marine electric propulsion system.

船用电力推进系统电能质量改进方法的新概念
介绍了某型船舶电力推进系统的特点,阐述了该系统的电能质量现状。分析了目前船舶电力推进系统中应用的电能质量改进的意义。最后,提出了一种船舶电力推进系统的有源功率因数补偿器与串联有源滤波器相结合,并辅以并联无源滤波器的新方法。根据上述新方法的工作原理,可以预测该组合系统在船舶电力推进系统中具有补偿谐波和提高功率因数的前景。
