摘要
本文针对实际特高压直流输电工程调试过程各阶段入地电流大小不同,对接地极附近重要变电站的交流变压器进行直流偏磁电流大小、变压器振动幅度、变压器噪声测试,验证不同运行方式,不同入地电流情况下直流偏磁对在运变压器的影响。
This essay is focused on DC magnetic bias influences on AC power grid transformers based on an actual UHVDC project. By testing DC current flow through transformer neutral point, transformer vibration and transformer noise level under different testing stages, the DC magnetic bias influences on AC transformers have been illustrated.
