The safe operation and maintenance of the substation channel can ensure the safe operation of the power system.Therefore,the method of safe operation and maintenance of intelligent substation channel is proposed.By eliminating the frequen-cy difference between different channels,the received signal at the AP end of the smart substation and the maximum likelihood function of the smart substation channel are obtained,and the continuous variable integral of the signal sequence is obtained to detect the smart substation channel signal.According to the arrangement of the collection points of the security information of the smart substation channel,the security operation and maintenance model of the smart substation channel is constructed,and the se-curity operation and maintenance of the smart substation channel is realized through solving.The results of the example analysis show that the proposed method can improve the accuracy of substation channel safety operation and maintenance.
