基于Multisim的三相交流负载星型连接电路仿真

Multisim-based simulation of the three-phase AC load star connection circuit

三相交流电路星型连接是电路连接的重要形式.利用Multisim仿真软件,研究三相负载在星型连接时,有中线负载变化、无中线负载变化对电路的影响及中线的作用.仿真结果与理论分析结果一致,仿真效果较好.

The three-phase circuits star connection is an important form of circuit connection. This paper studies the Multisim-based simulation of three-phase AC load in star connection circuits, influences of variable load with/without neutral lines, and functions of the neutral lines. The ideal result of simulation is consistent with that of the theoretical analysis.
