P－Q分解法潮流计算的直角坐标解法

The Solution to the Decoupled Power Flow Method in Rectangular Coordinates

将电力系统潮流计算常用的Ｐ－Ｑ分解法各计算公式完全以直角坐标形式表示，从而大大减少了三角函数计算。不但提高了计算速度，而且使计算过程简化。以一个四结点系统为例给出了计算结果。

The individucql formulas of the decoupled power flow method which are oftenused in power systems are expressed in rectangular coordinates.It can greatly reduce the calculation number of the triangular functions,increase the calctilating speed and simplify the calculatingprocesses in the decoupled power flow method.The paper takes a four-bys system as the exampleand makes the detailed analyses and comparisons between the decoupled power flow and the improved methods。
