Анализ электромагнитных вибрационных сил в элементах крепления статора турбогенератора к корпусу при неноминальных режимах работы

Abstract

For the first time for TGs operating in non-nominal modes, the estimation and calculation of additional EMF in the elements of the TG core fastening to the case are carried out, which are created by the leakage fluxes of the back of the stator core and supplement the action of the basic EMF. The definition of these forces is relevant, because turbogenerators of TPPs in Ukraine with a capacity of 200-300 MW are maneuvering capacities and solve the problem of maintaining the power factor of the power system.
