摘要
随着船舶自动化程度的不断提高,船载电力设备的数量和功率也在不断增加,一方面提高了船舶的运行质量,另一方面也对船舶电力系统的性能提出了更高的要求。为了满足日益增大的电力功率需求,传统的船舶低压电力系统逐渐被中压直流电力系统所取代。中压直流电力系统具有稳定性高、输电损耗小等优点,目前获得了较广泛的应用。本文针对船舶中压直流电力系统的变流与功率优化问题,开发了一种基于MMC多电平换流器的船舶中压直流电力控制系统,并详细介绍了中压直流电力系统和MMC多电平换流器拓扑结构的原理,具有重要的意义。
With the continuous improvement of ship automation,the number and power of ship-borne power equipment are also increasing.On the one hand,it improves the quality of ship operation,on the other hand,it also puts forward higher requirements for the performance of ship power system.In order to meet the increasing power demand,the traditional low-voltage marine power system is gradually replaced by the medium-voltage direct current power system.Medium voltage direct current(MVD)power system has the advantages of high stability and low transmission loss,and has been widely used at present.Aiming at the problem of converter and power optimization in ship medium voltage DC power system,a ship medium voltage DC power control system based on MMC multi-level converter is developed.The principle of the topology structure of medium voltage DC power system and MMC multi-level converter is introduced in detail,which is of great significance.
