磁暴对中国电网的影响
|
摘要
通过比较2004年11月以来十几次磁暴数据与变压器中性点电流数据的相关性,证明了变压器发生的振动和噪声增大现象是磁暴在电网产生的地磁感应电流(GIC)所为,指出了磁暴对我国电网影响较大,磁暴对电网的影响已成为迫切需要研究的问题。
By comparison with relativity between the a dozen large number data of the magnetic storm since Nov.2004 and that of the current of the transformer neutra1 point,the paper proved that abnormal phenomenon of bigger vibration and greater noise in transformer arose from GIC in the electric power network,which induced by magnetic storm,and pointed out magnetic storm have greater impact on chinese power grid,and magnetic storms issue have an urgent need to study.
