文档介绍：1 摘要首先简单介绍了基于在 MALAB 中行潮流计算的原理、意义, 然后用具体的实例, 简单介绍了如何利用 MALAB 去进行电力系统中的潮流计算。电力系统潮流计算是研究电力系统稳态运行情况的一种计算, 它根据给定的运行条件及系统接线情况确定整个电力系统各部分的运行状态:各线的电压、各元件中流过的功率、系统的功率损耗等等。牛顿-拉夫逊法在电力系统潮流计算的常用算法之一, 它收敛性好, 迭代次数少。本文介绍了电力系统潮流计算机辅助分析的基本知识及潮流计算牛顿-拉夫逊法, 最后介绍了利用 MTALAB 程序运行的结果。关键词:电力系统潮流计算,牛顿-拉夫逊法, MATLAB 2 The Abstract At first, this paper briefly introduces the theory and the meaning of the load flow calculation based on MATLAB, and then it briefly introduces how to apply MALAB to the load flow calculation of the power system by concrete cases. A kind of calculation is the load flow of the power system, which studies the stable operation-condition of the power system. It confirms the operation-condition of the whole power system, such as the voltage of every line, the rate of power crossing ponent, the rate of power consumption of the system, according to the given operation-condition and the connected circumstances of the system. Newton-Raphson method monly used in the load flow calculation of the power system for its good stypticity and little iteration. This paper introduces the basic knowledge about the assistant analysis of the load puter of power system and the Newton-Raphson method. Finally, it introduces the results after making use of MALAB procedure. The key word:The load flow calculation of the power system; Newton-Raphson method;MALAB 3 目录摘要............................................................................................................ 1 1 设计背景.................................................................................................. 3 2 原始资料分析.......................................................................................... 4 3 拟分析方法.............................................................................................. 7 4 设计步骤.................................................................................................. 8 程序流程图...................................................................................... 8 程序清单....
