This paper proposed a low voltage AC series fault arc identification method based on artificial neural network in microcontroller.The experimental platform of AC series fault arc was built,the signal acquisition board based on STM32F407ZGT6 microcontroller and AD7606 chip was designed,and the artificial neural network model was constructed by using TensorFlow.The artificial neural network model was trained by odd harmonic data acquired under normal operation and fault arc induction,and subsequently input into the STM32F407ZGT6 microcontroller for fault arc i-dentification.Experiment results show that the proposed method can accurately identify AC series fault arc.
