交流支路的电气剖分方法(一)普通支路的剖分

Electrical Dissecting Method of AC Branch Part One Dissection of Ordinary Branch

用传统的电力网络分析方法很难准确得到网络源流沿交流支路传输的路径剖分信息。针对此问题,从电力网络的基本原理出发,给出了交流支路3类电气剖分的定义,构造了3类电气剖分的方法,归纳出相应的电气剖分定理。由这些方法和定理可以准确地掌握网络源流沿剖分子路径传输的电气量的性质和数量,且剖分子路径与原支路具有电气上的等效性,并严格满足电力网络的基本电气规律。算例结果显示了所提出的方法和定理的正确性。最后,简述了电气剖分的优点及进一步工作的重点,并就相关问题进行了讨论。

Using conventional analysis method of electric power network, it is difficult to obtain exact branch dissecting information with different sources and flows of network transmitting along AC branches. This paper gives definitions and constructing methods of three kind of electrical dissections of AC branches, and establishes corresponding dissecting theorem. By using these methods and theorem, electrical characteristics and quantities of different sources and flows along different dissecting sub-branches can be obtained. Dissecting sub-branches of one branch is electrically equivalent to the original one and strictly satisfies various principles and laws of electric power network. Example systems show that the method and the theorem are correct. Finally, this paper briefly summarizes advantages of electrical dissecting of AC branch and future work in the field.
