Failure Analysis and No-Load Voltage Waveform Optimization and Damper Bar Heat Reduction of a Large Tubular Hydro-Generator

Article Preview

Abstract:

For the failures of a 30MW tubular hydro-generator such as no-load voltage waveform is bad, damper bars are over heat, a multi-slice moving electromagnetic field-circuit coupling FE model of tubular hydro-generator and a 3D temperature field FE model of the rotor are built respectively.And the computations about the failure reasons and the optimized design schemes are implemented and analyzed by these modles.And the calculation results are coincident well with the test data.
