Welcome to The Deep End. This is Episode three hundred ninety-two: Synchronous Generators, Excitation Systems, and Power System Stabilizers: Park's d-q Transformation, Subtransient Reactance, AVR Loops, and Sub-Synchronous Resonance. Let us begin on the afternoon of October twenty-sixth, nineteen seventy, and again on December ninth, nineteen seventy-one, inside the turbine hall of the Mohave Generating Station in Laughlin, Nevada—where two brand-new $790\text{-Megawatt}$ cross-compound coal-fired steam turbine-generators were pushing $500\text{-kilovolt}$ AC power across the Mojave Desert…
