Abstract

Abstract: In the power system, electronic current transformer based on the Rogowski coil has been widely used in digital substation. Based on the analysis of its composition and structure, the electronic transformer is simulated by the Simulink module in Matlab. Rogowski coil is used to simulate the traditional transformer. Using Σ-Δ ADC converter and digital filter, analog signal from the high-pressure side is converted to digital output data, which is sent via fiber optic Ethernet to FPGA development board after FT3 format framing by Simulink. The data is then sent to the merged unit of transformer’s interface after Manchester encoding and decoding, and CRC check. The network’s interface gets the FT3 frame format data which satisfies the design’s requirement.

Key words: Rogowski coil, Σ-ΔADC, FT3, FPGA
