几种电力系统潮流计算的比较与分析

Comparison and Analysis of Several Calculations of Power System Flow

电力系统潮流计算是对电力网规划、运行研究分析的一种方法,其在电力系统中具有举足轻重的作用。本文旨在利用C语言根据潮流计算原理编写出牛顿——拉夫逊直角坐标法、牛顿拉夫逊——极坐标法、P-Q分解法以及高斯—赛德尔法的潮流计算程序,然后对不同潮流程序进行比较,其中校验实例采用IEEE标准算例,分析出它们各自的适用场合及优越性。

Power system power flow calculation is one of the research on power grid planning and operation analysis method, it plays a decisive role in the power system. The purpose of this paper is to use C language and write Newton-Raphson method rectangular coordinate method, Newton-Raphson method-polar coordinate method, P-Q decomposition method and Gauss-Seidel method of power flow calculation program according to the principle of power flow calculation. Then, compare with different trend programs, including check instance USES the IEEE standard example, this paper analyzed their respective applicable occasions and superiority.
