To study the harmonic characteristics of circulating current between the stator windings in parallel branches of the hydro generator under eccentric faults, the mechanism of circulating current is theoretically analyzed. On this basis, an eccentric fault model of the hydro generator is established by ANSYS, and the eccentric fault model is simulated and calculated to obtain the harmonic characteristics of the circulating current. The results indicate that the magnitude of circulating current increases with the degree of eccentricity. Under static eccentric faults, odd-order harmonic circulating currents are generated, while under dynamic eccentric faults, both odd-order and fractional-order harmonic circulating currents are produced.
