摘要
三相-六相混合电力系统已有20多年的运行历史,由于六相输电系统结构相对复杂,为系统分析、计算带来了不同于三相系统中的许多新问题,现有的对这种混合输电系统的计算方法繁琐复杂。在对此进行深入研究和探讨的基础上,提出了一种将六相电压、电流变换为三相电压、电流的计算方法,借助于此方法,可将六相系统简化为三相系统,从而可将三相-六相混合输电系统的分析转化为三相电力系统的分析,还特别研究了六相系统中的线路阻抗,三相-六相变压器的三相等效原理。
This paper presents a novel approach for calculations and analysis of the mixed three-phase and six-phase power system. A mathematical model of sum and difference components is established. By means of the model, a set of six-phase elements can be transformed into two uncoupled three-phase elements, and three-to-six-phase power transformers can be replaced by a three-phase transformer with three-windings, the analysis to the mixed three- phase and six-phase power system hence can be reduced to the analysis of a three-phase power system..
