摘要
为了更好的进行配电网故障区域的诊断,基于配电网的有向分层模型,提出了一种配电网故障区域判断的新方法。首先根据配电网的有向分层模型,建立配电网的网络描述矩阵D。根据FTU得到的故障过流及方向信息,并加入到网络描述矩阵D的相应位置形成故障判断矩阵DP,根据DP中相应元素的值就可以完成对最小配电区域故障的查找。该方法无需进行矩阵相乘的繁琐运算。可以快速,准确的查找到故障区域。
Inorder to carry on the distribution network fault region the diagnosis. Based on the distribution network＇s orientative layering model, propose a new distribution network fault region judgment method. First, according to the distribution network＇s orientative layering model,build distribution network＇s description matrix D. Fault overflow and direction information are obtained according to FTU, and joins in the network description matrix D relevant position forms the fault judgment matrix DP, It can complete deticve of the smallest fault distribution region according to the corresponding element＇s value. This method does not need carrying on the matrix multiplication the tedious operation. It can be fast, accurate and searching fault region.
