摘要
随着大型电源基地的建设,高压直流输电系统将成为重要的输电通道之一。在单极大地回线方式下,高压直流输电系统接地极电流对中性点直接接地变压器产生一定影响。分析了产生这些影响的机理,列举了国内外几个直流输电系统产生影响的实际情况,总结了目前采取的一些主要措施。在特高压直流输电系统规划建设中,要进一步加强特高压直流输电系统接地极电流对交流电网影响的研究。
With development of large power base, HVDC is becoming a important method to transfer power. When unipole-groundreturn mode is adopted, the earthing electrode current influences on directly grounded transformers. The mechanic of these influences is analysised in this article. The fact resuks of influences made by some HVDC are also presented. The influences of UHVDC on AC power grid should be imported during design and construction of UHVDC.
