Study on corrosion fault diagnosis for grounding grid based on the Tellegen' s Theorem
摘要
Abstract
Grounding grid is the key measure for the safe operation of power system and the guarantee for the safety of workers and electrical equipment .Once the grounding grid fails due to corrosion and other reasons , the power system security will be in danger .Aiming at the corrosion fault diagnosis of grounding grid , this paper established diagnostic equations of grounding grid fault based on Tellegen 's Theorem, and used iteration method to solve the equations .As a result , we can find fault branch which is caused by corrosion .From the experimental result , we can see that the di-agnosis method can find the corrosion fault effectively , and increase the operational reliability of grounding grid in power system .关键词
