| 摘 要： | 在电力系统潮流计算中，通常用节点导纳矩阵形式的节点电压方程描述网络的数学模型，而在电力系统短路电流故障分量（基频交流分量初始有效值）计算中，为什么要使用网络的节点阻抗矩阵？本文对这个问题作了比较深入的分析，并据此阐述了《电路原理》与《电力系统分析》课程在理论性与实际性方面存在的差异。

| Abstract: | In the power system load flow analysis,we used to describe the model of power network through the admittance matrix node voltage equations.However,in the power system short circuit calculations,why we used to describe the model of power network through the impedance matrix node voltage equations?The difference between the admittance matrix node voltage equations and the impedance matrix node voltage equations are discussed in this paper.Furthermore,the difference in the theoretical and practical aspect between the subjects of electrical circuit theory and power system analysis are pointed out. |
