In the study of power system design and the current operation mode are required Power Flow Calculation to quantitatively analyzed pared to the program or run mode power supply reasonable, reliability and economy or not. MATLAB is easy to use, the powerful matrix processing is the other high-level language can not pared with. This allows MATLAB to e the puter language of power flow calculation. Newton Raphson power flow calculation is one of the monly used algorithms, which has good convergence and fewer iterations .This article describes the power puter assisted analysis of the basic knowledge and power flow Newton - Raphson method, Finally it describe how to use matlab to make the power flow calculation software. Keywords: work power flow calculation; Newton - Raphson method; matlab xx 大学毕业设计(论文) - 1- 目录 1摘要.......................................................................................... 1 2 Abstract .............................................................................................. 2 3第 1章绪论................................................................................... 2 1 配电网潮流计算研究的目的与意义............................................................... 2 潮流计算简介..................................................................................
