TRANSIENT MODELING OF AC MACHINES CONSIDERING SECOND ORDER EFFECTS


Abstract

In this paper, the transient simulation of AC machines considering spatial field harmonics and current displacement in rotor bars is examined. The first point of discussion is the sufficient order of the equivalent circuit of the current displacement model for its accurate co-simulation with the higher spatial field harmonics. In the second place, the problem of inversion of the inductance matrix considering the flux linkage through higher spatial harmonics is studied.
