摘要：

The generalized remote operation of protective relay refers to all the business operation orders involving operational mode changes and operating maintenance arising from an external substation or an internal one. Such remote operation should follow a strict business control with high cyber security guarantee, which is an urgent engineering task demanding prompt solution. A closed-loop business supervising and control mechanism is proposed with the remote operation order sheet (ROS) uniformly signed and issued by the dispatch control center and uniquely executed by a novel secure operation module for protective relay (SOMR) in substation. The encrypted and extensive markup language formatted ROS will be prepared in safe zone III at the dispatch control center, and transferred to SOMR in IEC 61850 file mode, through a uniform ROS platform in safe zone I at the dispatch and control center. SOMR will execute ROS to target protective relays, to fulfill the orders such as protection setting, setting operation zone change, soft strap turn on or off, signal return, setting periodic verification, etc. plus the authorized site operations auto-monitoring and trace recording. The ROS modeling, and its digital signature and encryption selection, are also presented. Finally, the advantages and necessity of the proposed scheme are demonstrated. © 2016 Automation of Electric Power Systems Press.
