摘要
介绍了一种现代船用电力系统谐波分析方法,旨在为解决该类系统的谐波干扰问题提供参考.文中推导了12脉波和24脉波整流单元交流电网谐波的表达式,理论上分析了移相变压器对谐波分量的抑制原理,在实验室中对一套模拟电力系统进行了现场测试,实验结果对计算模型的准确性进行了验证.
This paper aims at offering a simple and accurate harmonic analysis method of modern ship electric systems, as well as giving some hints for possible further improvement of them. The formulas of the line current harmonic are given for 12-pulse and 24-pulse circuit. The principle of harmonic elimination for phase-shifting transformer is theoretically analyzed based on the harmonic models. The proposed method is verified by field measurement results from a ship power system prototype.
