Abstract:Through the analysis of the key links of remote operation of substation sequence control,the safety risks in the process of remote operation of sequence control are investigated,and the corresponding safety protection measures are put forward from different angles. The focus is on the safety risks and prevention and control measures in each link of remote operation. If the process risk and safety control of remote operation of sequential control are strengthened,it is of great significance to ensure the safe and stable execution of substation sequential control,greatly shorten the operation time of substations,and reduce the related economic losses and social impact.
