AVR_VOLT_CTRL
Generator terminal-voltage PI controller with reactive droop, synchroniser and VAr-sharing bias, and a clamped excitation demand.
When to use it
Use AVR_VOLT_CTRL when a generator's excitation is regulated from a terminal-voltage measurement — constant voltage on its own, or on reactive droop in parallel — and the excitation demand has to accept trims from a synchroniser's voltage matcher and a VAr-sharing line.
