Analysis and Calculation of Damper Winding Losses in Cycloconverter fed Synchronous Machines

本文阐述了凸极同步电机中谐波增量磁场的作用及特点。给出了可计及包括端部影响的任意复杂转子回路的场路耦合计算格式。针对交交变频同步电机阻尼绕组的计算问题 ,提出一种等效多端口网络的概念 ,并据此对两种阻尼绕组结构的损耗进行了分析比较。

The effect and feature of harmonic incremental magnetic field in salient pole synchronous machines are described. The field circuit coupled calculation format is given, where arbitrary complex rotor circuits considering end effect can be taken into account. To solve damper winding calculation of cycloconverter fed synchronous machines, a concept of equivalent multi port network is presented, and by this method, a comparison between two damper winding structures in loss is made.
