The Effects on Chinese Power Grid by Magnetic Storm

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.
