双三相电机开路故障后电流参考生成策略的变流器损耗对比研究

Comparison of Postfault Strategies for Current Reference Generation for Dual Three-Phase Machines in Terms of Converter Losses

语言:

中文摘要

双三相电机具备固有的容错能力。现有研究多关注开路故障后的定子绕组损耗,忽略了变流器损耗。本文旨在对比不同电流参考生成策略对变流器损耗的影响,以优化故障后的系统性能与可靠性。

English Abstract

Dual three-phase machines are attractive due to advantages such as inherent fault tolerance. Several strategies for current reference generation have been proposed to improve the postfault performance under open-phase fault. However, for the development and analysis of these strategies, only the stator winding losses were considered, but not the converter ones. In fact, there are no studies so far...
