Abstract

StrafloMatrixtrade system is considered as an innovative application form in the area of small hydro power, which operates with PM synchronous generators directly coupled to the grid. Two StrafloMatrixtrade generator prototypes are presented with their design featuring high-voltage windings with open stator slots and the damper cylinder on the rotor. The no-load additional losses due to stator slot harmonics are calculated using a numerical model with equivalent current layer. The telephone harmonic factors for both prototypes are calculated based on the FE analysis to be compared with the measurement results.
