Research on the Plan of Independent Earth Electrode Reconstructed to Common Earth Electrode
-
Abstract
Inorder to solve the difficulties of earth electrode site selection and environment problems in DC transmission engineering, the proposed solution is to reconstruct independent earth electrode to common earth electrode. The main performance such as step voltage, corrosion life, maximum temperature rise, conductor capacity must be verified during the transformation period, and according to the verification results to determine the corresponding transformation project. At the same time, the effect of earth electrode on AC power network, oil and gas pipeline, railway facilities should be reviewed.
