Synchronous machine performance under geomagnetic disturbances

Geomagnetic disturbances (GMDs) are known to disturb power system equipment performance. The danger is associated with geomagnetically induced currents (GICs) occurring at the Earth's surface during GMD. GICs do not endanger operation conditions by themselves. main challenge posed states change in provoked GIC flow. primary avenue of blackout caused GMDs through transformers. This, turn, can impair other such as synchronous machines. Modern powerful machines designed and engineered cope negative impacts GMDs. Moreover, actual legal norms inadequate this case. Enhancing grid's resiliency an event highly interesting industry. physical processes machine windings triggered limitations brought grid operations described. First, idea impact on analysis performed second section. In end, response under studied.
