The Comparative Study on Influence on the Northeast China UHV Planning Power Grid Induced By Different Kind Geomagnetic Storms
Along with the UHV construction scheme,China will form a large number of transmission lines which have the characteristics of the ultra-high voltage,large-capacity,long-distance.Because the UHV power grid transmission line parameters and the structure of the grid and the transformer are different from the other power net,Geomagnetic storms will affect the UHV power grid more,the work have important significance to the assessment of the ultra-high voltage power grid level and influence.The impact of different storms on the grid are also different.Based on the power flow mechanism of the GIC,different data and network parameters of geomagnetic storms,the evaluation model of the GIC is established,we assess the result of the GIC induced by the geomagnetic storms happened on November 2004 and December 2006 in the 2020 planning ultra-high voltage power grid,find out the greatest impact transformer substation and the timing analysis results of the grid compare the different impact of different storm..The comparison of the analysis results is helpful for understanding the different kind geomagnetic storms and the regional features of GIC.
