摘要

本文研究了发电机转子匝间短路不同位置时发电机端部绕组的振动。首先。研究了短位置对气隙磁通密度的影响。在此基础上。，得到端部绕组的电磁力(EF)。然后，通过有限元分析和实验对理论分析模型进行了验证。结果表明，RISC故障会给EF带来额外的(50Hz, 150Hz, 200Hz)谐波。此外，随着短位置离大齿的距离越来越远，端部绕组的振动也会增加。

Effect of RISC Positions on End Winding Vibrations in Synchronous Generators

The vibration of generators end windings in rotor inter turn short circuit different (RISC) locations is studied in this article. Firstly., the influences of short locations on the air gap magnetic flux density (MFD) are investigated. On this basis., the electromagnetic forces (EF) of end windings are obtained. Then, theoretical analysis model is validated through finite element analysis (FEA) and experiment. It shows that the RISC fault will bring additional (50Hz, 150Hz, 200Hz) harmonics to the EF. In addition, the vibration of the end winding will increase as the short location gets distant from the large tooth.
