Abstract
This paper used theoretical analysis and numerical calculation to analyze winding electromagnetic force (EF). QFSN-600-2YHG type turbo-generator is the research object. This paper investigated EF on exciting windings of turbo-generator before and after rotor interturn short circuit (RISC) fault. The impact of RISC on the air-gap magnetic flux density (MFD) was firstly studied. The EF formulas were deduced based on the air-gap MFD. Then the detailed EF values were obtained by numerical calculation. The winding EFs are of centrosymmetry under normal condition. RISC mainly affects the EF of the very coil where the short circuit takes place. As RISC develops, the EF will decrease. This study is probable to be beneficial to insulation monitoring.
