内蒙古科技大学电力系统稳态分析课程设计题目:基于 MATLAB 地电力系统复 杂 潮流分析学生姓名:刘建峰学号: 1167130207专业:电气工程及其自动化班级:电气 2011— 2 班指导教师:刘景霞摘要电力系统潮流计算是电网分析地基础应用,是对复杂电力系统正常和故障条件下稳态运行状态地计算.给定电力系统地网络结构、参数和决定电力系统运行状况地边界条件,确定电力系统运行地方法之一是朝流计算.MATLAB是一种交互式、面向对象地程序设计语言,广泛应用于工业界与学术界,主要用于矩阵运算.采用迭代法,通过建立矩阵地修正方程来依次迭代,逐步逼近真值来计算出电力网地电压,功率分布.PQ 分解法是极坐标形式牛顿 -拉潮流计算地一种简化计算方法,.P— Q 分解法通过对电力系统具体特点地分析,对牛顿法修正方程式地雅可比矩阵进行了有效地简化和改进 .由于这些简化只涉及修正方程式地系数矩阵,并未改变节点功率平衡方程和收敛判据,因不会降低计算结果地精度.用手算和计算机算法对其进行设计.使用 MATLAB软件进行编程,在很大程度上节省了内存,减少了计算量.通过对本题计算我们了解了一些工程计算和解决工程问题地方法 .关键词:潮流计算, PQ分解法, MATLAB Electrical power system complex tidal current analysis based on MATLABPower Flow Analysis Grid computing is the basis of applications, the complex power system under normal and fault conditions for the calculation of steady state operation. Given the power system network structure, parameters and decisions operation of the power system boundary conditions, to determine the method of operation of the power system is one of North Korea flow calculation.MATLAB is an interactive, object-oriented programming language, widely used in industry and academia, mainly for matrix calculation. Using iteration, the amendment through the establishment of matrix iterative equation to turn, gradually moving towards a true value to calculate the voltage electricity grid, power distribution.PQ decomposition method is the form of polar coordinates Newton - the widening trend ...
