中文摘要:

接地网是使电力系统可靠运行、保证工作人员以及电气设备安全的关键设施,一旦接地网因腐蚀等原因发生故障,将危及电力系统安全运行。本文针对接地网腐蚀诊断,基于特勒根定理,建立接地网故障诊断方程并利用迭代法求解,辨识发生腐蚀故障的支路。实验结果表明,该方法能够有效判定接地网的腐蚀故障,提高电力系统接地网的运行可靠性。

英文摘要:

Grounding grid of power system is the key measure for safe operation of power system and the guarantee for safe of workers and electrical equipment. Once the grounding grid fails due to corrosion and other reasons, the power system security will be in danger. This paper is aimed at corrosion fault diagnosis of grounding grid. Based on Tellegen Theorem, we establish diagnostic equations of grounding grid fault and use iteration method to solve the equations. As a result, we can find fault branch which caused by corrosion. From the experimental result, we can see that the diagnosis method can find the corrosion fault effectively, and increases the operational reliability of power system grounding grid.
