Studies And Designs Of Mu Based On Fpga In Substation Training Simulator

Substation training simulation system can enhance the power system operating post operation skills and ensure the safe and economic operation for power sector. With the development of modem power system and the increasing demand of the substation data communications, digital substation emerges.The new requirements are proposed for substation training simulation system.The merging unit for material substation simulation training is designed in this paper. According to FT3 format and IEEE802-3 format, the virtual current and voltage data of virtual primary side are sent to real secondary system,and converted them into the need analog of conventional substation simulation by this the merging unit device. For the merging unit has high reliability and flexibility, the hardware core unit of this the merging unit is chose by rich resources and programmable FPGA chip. This paper analyze a lot thing, such as the function of this merging unit, the synchronizing signal design, data decoding and frame, interpolation caculating, CRC checking, D/A transformation control , ethernet control module and so on. In order to accelerate accelerat accelerat acceleratthe data encoding and decoding ,framing and interpolation caculating, the module design adopts parallel technology as much as possible ,so as to transfer data to the real quadratic systems timely.The merging unit designed in this paper can meet the needs of both conventional substation and digital substation training simulation systems, as well as improve the reliability of equipment and shorten the data transmission time, is completely in compliance with IEC61850 substation automation communication standards.
