Abstract

This work considers a hybrid shipboard electrical-power system consisting of a shipboard electrical network with diesel generators, a shaft generator with a synchronous permanent-magnet machine, and two active semiconductor converters connected by a dc link with a capacitive filter. The converters, which are controlled by separate control systems, form a synchronized information-energy system that ensures two-way energy exchange between the shipboard electrical network and the main motor shaft in the absence of a buffer energy storage device in the dc circuit of the converters, which provides long-term compensation for the power imbalance of the entire shipboard electrical-power system. Methods for controlling the information-energy system are considered, allowing one to synchronously change the direction of power transmission in the shipboard electrical-power system and optimize its power performance.

舰载混合电力系统的分析与模拟研究
摘要 这项研究考虑了一种混合船用电力系统,该系统由一个带柴油发电机的船用电网、一个带同步永磁机的轴发电机和两个有源半导体变流器组成,这两个变流器由一个带电容滤波器的直流链路连接。这些变流器由独立的控制系统控制,组成一个同步信息能源系统,在变流器直流回路中没有缓冲储能装置的情况下,确保船用电网和主电机轴之间的双向能量交换,为整个船用电力系统的功率不平衡提供长期补偿。研究还考虑了控制信息能源系统的方法,使人们能够同步改变船载电力系统的功率传输方向,优化其功率性能。
