摘要：
The wide application of remote control business for modifying settings and switching setting groups in the master station of the protection information system puts forward higher requirements for the operation authority control and the network security. Combined with the features of the power system master station and the substation communication architectures and the current implementation status of the remote control business, the operation permission security control system is studied and developed. The design ideas, the system structure, the message processing flow, the device hardware design schemes and the system deployment schemes are expounded. The permission management of remote modifying settings and the network security protection are strengthened under the conditions that the existing business system architectures, the applied programs and the system configuration remain completely constant. The verification examples in both the laboratory and application sites are given, the application effects are summarized, and the further research direction of the usage scenarios to be expanded is prospected. © 2022, Power System Technology Press.
