| Abstract: | The feeder protection configuration of DC traction power supply system was introduced in this paper, and some problems of current-rising-rate protection and current increment protection were discussed. Based on combining the current-rising-rate protection with current increment protection, the colligation protection of current-rising-rate and current increment was proposed. The combination protection principle was discussed. The application of the colligation protection of current-rising-rate and current increment was presented by an example of Beijing subway system. |
