网侧变流器的稳定运行对可再生能源系统至关重要。本文提出了一种针对网侧变流器电压和电流传感器故障的基于模型的诊断方案,旨在通过反馈信号的实时监测与分析,提高变流器在并网过程中的可靠性与故障容错能力。

English Abstract

The effective operation of the grid side converter is crucial for the reliability of renewable energy systems. Grid side converters are responsible for converting the energy produced by renewable energy sources into a form that can be injected into the grid. A grid side converter controller manages the conversion using feedback from voltage and current sensor measurements from both the alternative...
