Abstract

To research the influence of rotor structure on field current and rotor electromagnetic field of a turbine generator under Out-of-Phase Synchronization(OPS), an 2-D Field-Circuit-Grid Coupled Model (FCGCCM) of the 150MW turbine generator is established. By using the established FCGCCM, the influence on field current and the field current oscillation ratio (FCOR) under OPS of 180° was studied, when rotor slot indexing number was changed and magnetic slot wedge was used on common slots. A magnetic nonuniform coefficient (MNC) was proposed to evaluate magnetic field nonuniformity of the rotor. The relations of MNC to rotor indexing number and magnetic slot wedge were investigated.
