Black Start, System Restoration, and Grid Resilience: Cranking Paths, Cold Load Pickup, Transformer Inrush, Islanding Synchronization, and GIC/EMP Hardening

A thousand-megawatt steam or nuclear power plant cannot start itself in the dark: its own pumps, fans, and exciters need thirty to fifty megawatts of outside grid power before the boiler can light. When the entire grid collapses to zero volts, how do you pull a continent up by its own bootstraps without blowing up transformers on Ferranti overvoltage, stalling black-start generators on Cold Load Pickup, or tripping on harmonic inrush? And how did a solar geomagnetic storm collapse Hydro-Québec in ninety-two seconds in March 1989?
