《电力系统分析》课程设计报告 题目：复杂电力系统潮流分析程序设计 所在学院 电气工程学院 专业班级 12级电气工程及其自动化一班 学生姓名 陈剑秋 学生学号 201230088099 指导教师 房大中 提交日期 2014年 12 月 16日 摘要 电力系统潮流计算是电力系统分析课程基本计算的核心部分之一。它既有本身的独立意义，又是电力系统规划设计，运行分析和理论研究的基础。 电力系统潮流计算是对复杂电力系统正常和故障条件下稳态运行状态的计算，是电力系统计算分析中的一种最基本的计算。潮流计算是电力系统的各种计算的基础，同时它又是研究电力系统的一项重要分析功能，是进行故障计算，继电保护鉴定，安全分析的工具。电力系统潮流计算是计算系统动态稳定和静态稳定的基础。在电力系统规划设计和现有电力系统运行方式的研究中，都需要利用电力系统潮流计算来定量的比较供电方案或运行方式的合理性、可靠性和经济性 本课程设计采用P-Q分解法对三机九节点系统进行潮流计算。计算结果的得出是通过MATLAB软件编程实现。 关键词：电力系统潮流计算，P-Q分解法，三机九节点系统 Abstract Power flow calculation is the core part of the power system analysis course basic computing. It has both the independent meaning itself, and is the power system planning and design, the basic operation analysis and theoretical study. Power flow calculation is the calculation of the steady state operation of normal and fault conditions of complex power system, is one of the most basic calculation of power system calculation and analysis of. Power flow calculation is the basis of all kinds of power system calculation, and it is also an important function of power system analysis study, is the fault calculation, relay protection and identification, safety analysis tool. Power flow calculation is the basis of calculation system of dynamic and static stabilization. In the research of operation mode of power system planning and the existing power system, the rationality of power supply, reliability and economy of the program or run mode comparison requires the use of power flow calculation to quantitative The curriculum design using P-Q decomposition method for power flow calculation of the three machine nine bus system. It is concluded that the calculation result is achieved by MATLAB software programming. Keywords: power system power flow calculation, the P-Q decomposition method, three machine nine node system 目录 摘要 I Abstract II 一、 绪论 1 1.1 本课题的目的和意义 1 1.2 国内外发展现状 1 1.2.1 高斯-赛德尔迭代法 2 1.2.2 牛顿-拉夫逊法和P-Q分解法 2 1
