Research on corrosion detection methods and protective measures of GD in power system

The grounding device (GD) is easy to be corroded in the relatively humid and dark environment, which will affect the safe and stable operation of the power system. This paper creatively puts forward the corrosion detection methods and protective measures of power system GD. Firstly, the corrosion mechanism of GD is revealed from the corrosion environment and the parts prone to corrosion of GD, and the influencing factors of corrosion are analyzed. Secondly, the corrosion detection model of GD is established and solved by improved genetic algorithm (IGA). Then, the effectiveness of the proposed detection method is verified by a numerical example. Finally, from the aspects of material selection, resistance reducing agent and protection method, the anti-corrosion measures of GD are given. The research results can effectively reduce the occurrence of corrosion of GD in power system.
