Abstract

Inverter open circuit faults (IOCFs) in AC drives lead to undesired effects and thus, the reconfiguration of the drive to a post-fault operation mode is desirable. In the past some authors have proposed drive topologies and operation strategies to keep the drives operating after IOCFs. However, increased losses and temperatures during these post-fault operation modes lead to a reduced performance of the machine. This paper analyzes the occurring losses and the thermally defined operation limits of an induction machine during the post-fault operation. The analysis is performed by means of symmetrical components, finite element analysis and lumped parameter models.
逆变器开路故障后运行期间的电机利用率
变频器开路故障(iocf)在交流驱动器导致不希望的影响,因此,驱动器的重新配置到故障后的操作模式是可取的。在过去,一些作者提出了驱动器拓扑和操作策略,以保持驱动器在iocf后运行。然而,在这些故障后操作模式中增加的损耗和温度导致机器性能降低。本文分析了感应电机在故障后运行过程中产生的损耗和热定义的运行极限。采用对称构件、有限元分析和集总参数模型进行了分析。
