Abstract:

太阳黑子异常活动而导致的具有准直流特性的地磁感应电流(geomagneticinducedcurrent,GIC)的峰值远远高于变压器允许承受的直流量,已引起国内外多个电网相继发生电气设备受损和电网崩溃的事故。分析了GIC产生的机制,以及GIC致使变压器出现直流偏磁的原因。文中指出通过变压器的直流偏磁,GIC可能对交流电网的设备和电网的安全稳定运行构成威胁。详细分析了不同类型高压直流输电GIC存在的可能性,指出长距离高压直流输电只有在2种运行方式下,直流线路中才会出现GIC;正常运行时,该直流GIC不会危及直流输电的运行。最后提出了开展GIC对交直流系统安全稳定运行研究工作的建议。
