自环流网络潮流追踪法的研究

Research on Power Tracing Method in the Loop Flow Grid

潮流追踪法是损耗分摊的重要方法之一,基于图论的追踪方法分摊原理清晰,计算速度快,但是还不能解决自环流条件下的追踪问题。本文在图论理论快速追踪法的基础上,提出了一种基于节点-支路关联矩阵的自环流检测方法,并给出了一种求解自环流节点的节点损耗的方案,同时结合简单算例证明了该方法分摊结果的正确性。

As an important method of loss allocation, power tracing method based on graph theory has the advantages such as clear theory and fast calculation, but it will be disabled in the loop flow grid. Based on graph theory, a method to detect if there is a loop flow in the grid is proposed, a way to deal with those nodes composing the loop flow is given, as well as its validity in an example is proved.
