Title Intelligent Substation merging unit simulation device based on NI platform
Abstract
Under the background of the smart grid, the intelligent substation growing scale of development, IEC61850 is an international standard for digital communications system structure of intelligent substation in the future, which makes modeling techniques using object-oriented and have a future-oriented open architecture. Its goal is to achieve the interoperability between devices made by different manufacturers, which reflects the development direction and trend of intelligent digital substation communications, and cause wide attention of domestic and foreign power industry.
This paper describes the functions of the merging unit, through the IEC61850 communication protocol, and the actual operation of the substation and other aspects, analyzes the development of intelligent substation merging unit.The LabVIEW of the NI CRIO platform is mainly used in simulation and functional verification of merging unit, and the main function of the merging unit is realized, also the hardware platform is verified.Finally, the development of the merging unit is prospected.
