A Novel Quadratic Formulation of Load Flow Equations in Rectangular Coordinates

本文发展了电力系统潮流方程的一般表达型式。根据直角坐标形式下，潮流方程的特殊二次结构性质形成了潮流二次方程新的表达形式，并且给出了描述节点功率注入方程二次形式的人矩阵的结构和在这种新的表达形式下的雅可比矩阵，为潮流计算提供了一条新的途径和解算方法。

The general mathematical formulation of the load flow equation is developed in this paper. The special quadratic structure of the load flow equations expressed in terms of the bus voltages in rectangular coordinates form a novel quadratic formultion of the load flow equations. The structural properties of Ji matrices describing the quadratic form of the bus injection and the Jacobian matrix of the lOad flow equations are also described. A new route and solution method are provided for load flow calchlation methods.
