摘要：
A power system control apparatus has a power system impedance estimating circuit for estimating a power system impedance from an internal power of a generator, determined by an internal current thereof, and from a terminal voltage of the generator, and having a power system impedance estimating table, a power system stabilizer for suppressing a power fluctuation in power system in accordance with the estimated power system impedance, and an auto voltage regulator for keeping an output voltage of the generator at a constant value during a normal operation.
