摘　　要：在分析小阻抗支路对牛顿法潮流影响的基础上，结合电力系统网络的特点，提出了一种选取牛顿法潮流电压初值的新方法——小阻抗支路零功率法。分析与计算结果表明。The effect of small impedance branches on Newton Raphson load flow is analysed in this paper. A new method to give initial voltage values for Newton Raphson algorithms is presented. Analysis and experimental results indicate that the method put forward in this paper can prevent the divergence problem in Newton Raphson load flow for solving the system with small impedance branches.
