中文摘要:

带保护线的AT供电方式在结构上更加繁琐,网口数更多,进而相关电气量的计算也相应增多。快速准确的找到故障发生成为了研究热点。本文提出了采用夹角余弦法对带保护线的AT供电方式进行故障测距。利用分布故障测距方法应用于牵引网简化电路的分析,完成故障区间查找。最终应用Matlab仿真验证了该算法的有效性和可行性。

英文摘要:

AT power supply system with protection wire is more complex in framework,so it has more faults.The fault point should be found out quickly and accurately to repair the power supply systems.The paper estimates the area of fault based on the cosine between different fault current.Simulation analysis on Matlab/Simulink indicates that the arithmetic is not only easy but also a small amount of calculation,and the fault location principle is accurate and effective.
