Abstract

Three types of frequency converter (FC) structures are considered as parts of high-power electric ship propulsion systems—multilevel FCs, cascade FCs, and FCs with an active rectifier. Algorithms for controlling the power keys of converters with the structures under consideration are described. Mathematical simulation models for the electric power systems of ships with electric propulsion based on the considered FC structures have been developed. Calculations are performed for the values of voltages and currents inherent in the buslines of the main switchboards of ship electric power systems. Voltage nonsinusoidality coefficient as a key electric-power quality index of the ship electricity supply network is calculated. Voltage oscillograms have been obtained for the marine-vessel electricity supply network onboard the ship in the course of sea trials. The results of calculations and experiments have been compared.

摘要

三种类型的变频器(FC)结构被视为大功率船舶电动推进系统的一部分-多级FC,级联FC和带有有源整流器的FC。描述了用于控制具有所考虑结构的转换器的电源键的算法。基于所考虑的FC结构,已经开发了具有电力推进的船舶电力系统的数学仿真模型。对船舶电力系统主配电板的母线中固有的电压和电流值进行计算。计算出电压非正弦系数作为船舶供电网络的关键电能质量指标。在试航过程中,已经获得了船上船用电力供应网络的电压波形图。比较了计算结果和实验结果。
