摘要

介绍了双馈感应发电机控制回路的故障检测与重构。对定子电压进行了测量和观察。在无故障运行时，测量到的信号用于磁场定向控制。在电压传感器故障的情况下，错误的测量被识别，并使用观测器输出重新配置控制。无需测量定子电压即可运行。实验室测量证明了这一概念。

Voltage Sensor Fault Detection and Reconfiguration for a Doubly Fed Induction Generator

Fault detection and reconfiguration of the control loops of a Doubly-Fed Induction Generator are described in this paper. The stator voltage is measured as well as observed. During fault free operation, the measured signal is used for the field oriented control. In case of a voltage sensor fault, the faulty measurement is identified and the control is reconfigured using the observer output. Operation without measuring the stator voltage is possible. Laboratory measurements prove this concept.
