Excitation systems function as the \u201ccontrol heart\u201d of synchronous generators. They regulate DC currents inside excitation windings to control generator-terminal voltages and output reactive-power magnitudes. Operating-condition fluctuations are obvious in hydropower houses: variations of upstream water levels, load increase-decrease transitions and grid-side disturbances plus unit grid-connection and start-stop processes all bring drastic excitation-loop-load changes. Power-house workshops sustain year-round high-humidity and water-vapor-laden conditions; some underground workshops have limited ventilation and equipment readily suffers dew-condensation. Excitation systems adopt thyristor-rectifier schemes. Rectification processes generate massive harmonics and induce equipment-over-heating and current-ripple phenomena.
