Abstract

Generators with water-cooled stators and water-cooled rotor windings are often with aluminum conductor flat wires, which are close to the surrounding steel frame structure (SFS). The magnetic fields, generated by the strong alternating current in the busbar, can lead to eddy current losses in the steel structure and reduce its life cycle costs. In this paper, the influence on the SFS by the busbar is analyzed by using the finite element method. Firstly, the temperature distribution of the SFS is obtained through the coupled analysis of both magnetic field and the thermal field. Secondly, the thermal-protection measures are proposed and optimal designed in order to protect the SFS from overheating.
