The Sum Total of Nonlinear Terms and the Development of Load Flow Algorithm Retaiming Nonlinearity

本文根据台劳展开公式拓广了岩本伸一的保留非线性潮流方法,拓广的方法适用于一般的非线性方程组。给出了非线性总项(台劳展开公式中二阶项和高阶项之和)在保留非线性算法迭代过程中的简捷计算公式。

In this paper, the relationship, in the course of iterations, between the sum total of nonlinear terms (the second order and higher order terms in Tylor expansion formula) and the load flow equations in any coordinates is researched. The computation formula of the sum total of nonlinear terms is given out. The Iwamoto's (T-PAS, 1978) load flow algorithm retaining nonlinearity, which is only suitable for rectangular coordinates, is developed not only for rectangular coordinates but also polar coordinates.
