| Summary: | In order to solve the problems of low automation degree of substation relay protection test and poor management of test reports, a test and control technology for protection device based on Edge IoT is proposed. Based on the data storage and processing capability of cloud platform, an automatic test architecture based on Edge IoT is designed. The state assessment of protection device based on D-S evidence theory is established by further fusing multi-source information to improve the analysis level of automatic test of protection device. The management and control system forms dual test reports through edge computing and automatic test devices, establishes a mutual correction mechanism on the cloud platform, and adopts hierarchical encryption technology for report information to ensure the security and traceability of the test data. The research is applied to the project site, realizing the automatic testing of protection device, automatic generation and hierarchical encryption of test reports, and improving the efficiency and automation of testing. |
