Abstract
At present, IEC 61850 is the latest national standard work and system in the substations. IEC 61850 standard will extend further in the future. It includes relay protection, automation, power quality, high technology condition monitoring in the substations, and will be extended to all areas, such as wind power, hydropower, electric vehicles, distribution automation, energy storage
research status of the IEC munication protocols , the module of
communication based on IEC 61850 has been introduced with particular attention. Firstly, the paper describes the characteristics of IEC 61850 protocol architecture, object-oriented modeling technology in theory, and studies deeply the mapping between the protocols,
objects, and services of MMS and the IEC 61850 standard. munication module
based on IEC 61850 standard is designed and realized in the paper. The establishment of embedded Linux development environment and piler environment is introduced in detail. The U-boot start-up mode, start-up processes and migration process are described. As for the hardware system, this paper uses the ARM11 Development Board (S3C6410 is the core of microprocessor), ARM11 is as the core hardware circuit of IEC munication paper also introduces the extended logic controllers, prin
