Contributions to Elimination of Excitation Field Harmonics in Turbogenerators
Advances in Electrical and Computer Engineering, 2022 Turbogenerators driven by high-speed turbines are frequently used in electrical power generation. Power quality of a synchronous generator is directly associated with its excitation field harmonics. Conventional method to eliminate the most prominent harmonics is to distribute the slots to 2/3 of the rotor perimeter with equal slot pitches and ...
