Mitigating the impact of geomagnetic storms on the power system

Geomagnetic storms determined by the solar wind (a flow of the charged particles with the magnetic field) lead to specific problems with the power system modes, which can cause major accidents with extensive blackout of consumers. Similar problems accrue with the approach of the system elements arrangement to the magnetic pole of the Earth. Territorial position of the Russian North requires to consider the effects of geomagnetic storms on the power system operation by mitigation or restriction of the geomagnetically induced currents (GIC) in them.The paper is the continuation of researches on geomagnetic storm influence on the power system and is devoted to devices and level determination ways, and storm impacts mitigation on power system objects. Approaches to measuring instruments creation of the GIC on the Hall Effect and their specific implementations are considered. GIC mitigation ways by operation actions, and by restriction schemes are provided. The method of choice of quantity and place of inclusion of such schemes in the power system is shown.
