Abstract

A stability measuring method for a synchronous generator includes: S11: collecting electrical quantities, and setting an alarm PQ curve of the synchronous generator; S12: calculating a dynamic reactive power reserve, an inductive dynamic reactive power reserve and a capacitive dynamic reactive power reserve of the synchronous generator; S13: calculating a dynamic reactive power reserve target value, an inductive dynamic reactive power reserve target value and a capacitive dynamic reactive power reserve target value of the synchronous generator; and S14: calculating a capacitive stability, an inductive stability and a stability of the synchronous generator.
