基于Multisim的三相电路仿真

Simulation of Three-phase Circuit Based on Multisim

三相电路是日常生产和生活中应用广泛的电路,通过实验方法研究和分析三相电路的运行情况显得很有必要,但由于三相电路的实验有一定的危险性,而且某些故障性实验可能会对元件甚至整个电力系统造成破坏,因此三相电路的实验难以实施。通过三相负载对电路的影响的理论分析,阐述了供电系统中采用三相四线制的原因,并利用Multism仿真软件进行仿真。通过虚拟实验的方法验证了理论分析的结果,表明了运用Multism仿真是进行电路分析的一个有效手段。

There-phase circuit is widely applied to life and production,so it is important and necessary to research and analyse three-phase circuit thought experiments, nevertheless, the experiments are difficult to put in practice because these experiments are dangerous,and some fault experiments may harmful to components and power system, In order to illustrate the reason of using there-phase four-wire system in power system, the there-phase circuits are analyzed and simulated using Multism, Compared with theory, the simulative results of virtual experiments are satisfied,it indicates that it is effective using Multisim in circuit analysis.
