电力系统潮流多根算法及其初值研究

本通过分析潮流基本方程，推导出潮流方程实际上是一组圆方程，通过圆方程的两组交点建立潮流多根（解）的初值，并通过初值的不同组合方式建立了较详细多根探索法和简略多根探索法两种解算方法。

MULTIPLE LOAD FLOW SOLUTIONS AND ITS INITIAL VALUES IN ELECTRIC POWER SYSTEM

This paper proposes multiple load flow solutionsand its initial values in electric power system. The load now equations can be expressed as a group of circle equationsvia analyzing load flow equations. Its initial value of multiple load flow solutions can be formulated by virtue of circle load now equations. Two different solution methods (detailed search method of multiple load now solutions and simple search method of multiple load now solutions) are presented by means of different combination of initial value in load flow solutions, respectively. Under the various load levels, the methods have been successfully tested in Ward & Hale 6, IEEE 30, 57, 118'bus systems.
