Abstract
The change rules of reactive power loss of substations under different geo-electric intensity and direction are analyzed and then the GIC(Geomagnetically Induced Current) reactive power loss severity index of substation is defined. The index only normalizes the actual reactive power losses and does not change the relative relationship of reactive power loss among substations. Based on the index, an identification method for the areas susceptible to geomagnetic storms in a given system is proposed, which can provide a basis for grid planning and operation under the influence of geo-magnetic storms. Finally, a planned 750kV power system is taken as an example to verify the feasibility of the proposed index and algorithm.
