Research on Distributed Feeder Automation Communication Based on XMPP and GOOSE

Abstract

In the application process of distributed feeder automation (FA) that is based on peer-to-peer exchange of measurement and control data between smart terminal units (STUs), there is an urgent need for standardized communication interaction and necessary security protection. This paper proposes an IEC 61850 communication mapping scheme using built-in secure extensible messaging and presence protocol (XMPP) and the generic object oriented substation event based on the user datagram protocol (GOOSE over UDP) and a security protection scheme based on hash to obtain random subsets (HORS); one-time signature algorithm is used to ensure the communication safety of GOOSE messages. The agent-based distributed FA test system is developed with the STUs. The test results show the scheme can meet the requirements of the quick distributed feeder automation.

Applied Research on Intelligent Collection System of Positioning Information for Multi-source Heterogeneous Distribution Communication

“…The gradual increase in the demand for electricity has led to more demands from power companies for power supply capacity as well as distribution accuracy, and only by constructing a perfect distribution communication network can we truly meet the needs of grid generation as well as Moreover, Sun, L. et al analyzed the need for standardized communication interaction and security protection for point-to-point data exchange of distribution smart terminals and carried out the construction of a security protection scheme for distribution group networks using communication mapping protocols and user datagram protocols as a way to meet the secure communication interaction of distribution terminals [16]. Hu, K. et al utilized structure reserving state estimation for fault localization in distribution group networks, constructed a network topology model reflecting the changes of faulty nodes, and provided an effective solution for monitoring, protection, and control of DNS in distribution communication networks [17].…”

Research on distributed network information security diagnosis method based on matrix algorithm

“…At present, there are many experts and scholars who study the network information security management system, but most of them focus on single-level network security management, while the discussion and research on multi-level security management are relatively few [1] . Therefore, it is necessary to study and build a network information security management and control system that covers a wide range and can coordinate multi-level distribution and cross-network management, so as to effectively curb the attacks of malicious network codes and ensure the security of the network environment [2] .…”
