Abstract

In this paper, the permanent magnet synchronous generator of 1.5 MW output power which is driven directly without gear system is designed by conventional magnetic equivalent circuit method and analyzed by finite element method for verification of design. We analyzed the characteristics of generator like no load, rated load, short circuit condition and demagnetization of permanent magnet. The last, the analysis results of two kinds of rotor types are compared with each other. Especially the THD (total harmonic distortion) of output voltage is examined for the comparison.
