| 摘 要： | 首次提出了从理论上说“含非线性元件的三相电力系统中不可能出现平衡电路”的观点，并对这一命题进行了理论分析与证明，从而得出了对任一次谐波，三相非线性网络不可能用1个三相对称电路进行分析，而必须用3个对称电路进行分析的结论。文中给出了三相非线性电路的序网图分析方法和相关结论。实际的算例验证了这一结论。工程中现在使用的单线等效图方法只是工程上的近似。

| Abstract: | A fresh idea is proposed in this paper that a system, with loads of nonlinear voltage-current characteristics, can not be a balanced circuit. Theoretical analysis and simulations are given. One important conclusion is reached: in the analysis of harmonics of each order, three symmetric three-phase circuits, rather than only one-phase circuit should be used. An analytical method of the sequence circuits of harmonics in three-phase power systems is also presented. |

| Keywords: | sequence circuits of harmonics equivalent circuits nonlinear element substitution theorem symmetrical component method |
