Abstract


Substation grounding grid is the fundamental guarantee for power system’s safe operation. How to effectively reduce the grounding resistance of grounding grids, how to carry out grounding network corrosion protection, all of these problems are urgent to be researched and solved.This paper research and analysis the reasons of high grounding resistance of grounding grid and propose effective measures to reduce the grounding resistance and carry out application analysis on reduces resistance technology. In addition, the paper analysis of grounding grids corrosion mechanism, the soil factors impact on the grounding conductor corrosion, and propose effective measures to prevent the grounding conductor corrosion. Through the application of corrosion protection measures on actual substation grounding grid, the effectiveness and practicability of corrosion prevention technology were proved.The applied analysis of resistance reduction and corrosion prevention provides the theory basis and practice guidance for solving the high grounding resistance and easy corrosion problem of substation grounding grid. It will greatly enhance the substation grounding grid’s stability and security.
