摘要
针对高压直流输电单极大地回线运行时对变压器产生的直流偏磁现象,本文分析了其产生原因、抑制措施及消除机理等,结合800kV复奉直流对嘉兴电厂600MW机组主变压器造成的的直流偏磁现象及解决方法,提出了实用性较强的工程建议和观点。
According to DC magnetic of power transformer when HVDC transmission system is running under monopolar ground circuit operation mode, the reason,restrain measures and elimination mechanism were analyzied. Based on DC magnetic bias＇ phenomenon and solutions of Jia-xing power plant 600MW unit main transformers caused by 800KV Fu-feng HVDC transmission, some practical viewpoints and engineering suggests were also proposed.
