摘要
直流接地极是直流输电工程中换流站的重要设施,在单极大地回路运行方式和双极两端接地运行方式中分别承担着导引入地电流和不平衡电流的作用。±500kV直流接地极馈电电缆分流试验,可获取直流接地极电流分配是否均匀,衡量馈电电缆是否会超过其额定载流量。通过测量接地极馈电电缆分流数据及分流波形,最终确认大地返回运行系统是否满足设计要求。
DC earthing electrode is the HVDC converter station projects important facilities,the earth loop to run in a unipolar mode and bipolar mode operation at both ends of earth were introduced to assume the lead role of current and unbalanced current. ±500KV DC earthing electrode feeder cable shunt test, available DC grounding current distribution is uniform, measuring feeder cable will exceed its rated capacity. By measuring the earth electrode feeder cable streaming data and streaming waveform, finally confirmed to return the earth to run the system meets the design requirements.
