Abstract :
For pt.I see ibid., p.1241-6 (1992). The interaction between harmonic sources, other loads and the power system is investigated, using a power electronic simulator which performs an accurate time-domain analysis as described and verified in part I. An investigation is made of various load compositions involving power converter, three-phase induction motor, and constant impedance loads. The power system conditions studied include strong, weak, and parallel resonance. These results are compared with those from a simple Thevenin model of the power system to establish the limit of the model´s validity. An expression showing how the harmonic current injected into the power system is affected by load comparison is derived
