The invention discloses a relay protection data transmission system. The system comprises an FPGA interface board card, a simulator and a control protection device, wherein the FPGA interface board card is provided with a simulation interface module, a first FIFO module and a second FIFO module; the simulation interface module receives primary device data sent by the simulator, and the primary device data is written into the first FIFO module at a first preset speed; the first FIFO module sends the primary device data to the control protection device at a second preset speed; the second FIFO module receives the control protection data sent by the control protection device at the second preset speed; the control protection data is returned to the simulator at the first preset speed. When the technical scheme of the embodiment is applied, wiring is greatly simplified, the personal electric shock accident probability is reduced, and the safety is improved. The invention further provides arelay protection data transmission method. The relay protection data transmission method has the same advantages.
Description
Technical field [0001] The present invention relates to the technical field of intelligent substations, in particular to a relay protection data transmission system and method. Background technique [0002] At present, the transmission of primary equipment data and control and protection data is mainly carried out between the simulator and the control and protection device in the substation through the interface card, such as figure 1 As shown, the emulator sends the primary device data of the primary device to the interface board 01. The interface board 01 performs digital-to-analog conversion on the primary device data to obtain multiple current signals and voltage signals. The interface board 01 and the interface board 02 Connected by cables, each current signal or voltage signal needs a corresponding transmission line, which makes the wiring between the interface board 01 and the interface board 02 complicated. After receiving the primary equipment data, the interface board 0...
