【 摘 要 】

Geomagnetically induced current (GIC) caused by geomagnetic storms flows between the power grid and the earth would threaten the stable operation of the power system. Capacitor blocking device connected in series at transformer neutral point can directly block the DC path. However, due to the complexity of the DC path in the power system, before the installation of the blocking device, if global considerations are not taken into account, the adverse effects of GIC will not be reduced. Therefore, to study the position optimization of the capacitor blocking device is of great value. This optimization of placement of capacitor blocking device is proposed in this paper. Applying the idea of genetic algorithm, the installation quantity and installation position of the blocking device were calculated and compared with the traditional GIC non-optimal method, which verified the superiority of the genetic algorithm optimization solution.
