摘要
高压直流电将单极大地当作回路时,很容易出现直流偏磁,这会增加变压器损耗和无功补偿电容器实际运行负荷,因此需深入掌握直流偏磁特性,并积极采取有效措施。
When the unipolar earth is used as the loop in HVDC,DC bias is easy to occur,which will increase the transformer loss and the actual operating load of reactive power compensation capacitor.Therefore,it is necessary to deeply grasp the DC magnetic bias characteristics and actively take effective measures.
