葛洲坝——上海直流线路的人工故障试验分析

Analyses of the Manual Fault Tests of Ge-Shang DC Line

本文介绍了在葛上直流工程单极系统调试中修改和完善后的新的保护系统配置、葛上人工故障实验的实现方法以及人工故障试验的分析结果。

This paper describes the renewed allocation of DC line protection system and the principles of backward travelling wave, dv/dt-undervoltage, current differential protection and post fault algorithm, which have been modified during commissioning. Typical DC line fault tests carried out during the end to end test of Gezhouba-Shanghai HVDC project are also described.
