The No-Load Voltage Waveform and Damper Bar Temperature Computation of Integral Number Slots Large Hydro-Generator which the Number of Damper Bars per Pole Increased

Abstract:

In order to analyze the no-load voltage waveform and damper bars temperature of integral number slots large hydro-generator which the number of damper bars per pole increased, the 2D moving electromagnetic field-circuit coupling model of a 600MW integral number slots hydro-generator and 3D temperature field FE model of the rotor are established, and the no-load voltage waveforms and temperature are calculated. The research is helpful for improving design standard and enhancing the operation reliability of the large hydro-generator and electric network.
