Influence of Coke Bed on HVDC Grounding Electrode Heat Dissipation in Horizontal Multilayer Soil

摘要

The paper analyzes the influence of coke bed on I lie heat dissipation around HVDC grounding electrode. By living a method coupling moment method with boundary clement method, the influence of coke bed on the leakage current distribution is analyzed. Then the affected current flow distribution in the soil is achieved. By using a finite difference method, the temperature distribution caused by the affected current flow is achieved.
