Method and device for realizing sv subscription function of relay protection device based on fpga

Abstract

The invention relates to a method and a device for realizing a SV subscribing function of a relay protection device based on an FPGA (field programmable gate array). The method comprises the following steps of converting the original CID (configured IED description) file of a digitalized relay protection device into a .ini file, and extracting the related character field information of SV subscribing from the .ini file; converting the related character field information of SV subscribing into a corresponding bin configuration file, wherein the bin configuration file can be identified by a FPGA chip of the digitalized relay protection device; after the digitalized relay protection device is energized, downloading the bin configuration file to the FPGA chip; analyzing the bin configuration file through configuration analyzing logic of the FPGA chip, so as to obtain model information required by the SV subscribing function, and enabling the FPGA chip to realize the SV subscribing function through the model information. By adopting the technical scheme, the method has the advantages that the resource in the FPGA chip is saved, and the analyzing process of the model information required by the SV subscribing function is favorably simplified.
