Reactive droop compensation
WebSep 30, 1999 · Reactive droop compensation system and method United States Patent 6285168 Abstract: A system for controlling reactive currents in a generator is provided. A control system receives current and voltage feedback from the generator. The control system determines a phase angle based on the current and voltage feedback. http://www.pecplc.com/index.php/articles/control-of-synchronous-generators-with-droop-and-cross-current-compensation
