| Abstract: | The boundary value problem and the variational problem of eddy current electromagnetic field in the end region of turbogenerators are derived. The field in the end region of QFS-300-2 turbogenerators is calculated. The calculated results are identical to the measured results. The factors which affect the field are studied using quantitative method and qualitative method. This provides the basis to im prove the end structure design of large turbogenerators. |
