The conventional monitoring method of secondary circuit of substation relay protection is mainly based on virtual scene monitoring,which is difficult to achieve comprehensive coverage and affects the accuracy of secondary circuit monitoring.In this paper,a monitoring method of secondary circuit of digital substation relay protection based on deep neural network is designed.By identifying the unbalanced load current in the secondary circuit of digital substation,the change of the secondary circuit current is analyzed.Based on the deep neural network,the operation state and law of the secondary circuit of relay protection are monitored,and the visual display of the operation state of the secondary circuit is realized to avoid the monitoring error.The comparison experiment proves that the monitoring accuracy of this method is high and it can be applied to real life.
