把有限元法引入电力系统潮流分析根据电力系统潮流的特点，给出了电力系统中常见的单元模型，就此建立了系统的潮流方程用牛顿－拉夫逊方法求解非线性方程组给出了相应的分析程序并用实例进行了考核计算表明：有限元法的分析程序收敛稳定，程序可靠。

The finite element method is introduced into the analysis of power system's flow.Based on the characteristics of power system's flow,this paper puts forward not only a series of common element models of power system but also element's and power system's flow equations. And the paper solves the non-linear equations with the N-L method.Meanwhile,the paper also makes out the related programes in fortran and tests several practical examples.The results show that the convergent of the programes is stable and reliable.It may be referred and applied to the analysis of power system's flow.
