SV Protocol Controller Based on Precise Time Control of FPGA

Abstract

Digital input electric energy meter has been widely used in smart substation, this paper reviews three applications of smart substation digital input electric energy meter, correspondence analysis scheme of digital input electric energy meter accuracy. In order to analyze the digital transmission can affect the measurement accuracy of sampling value to quantitatively, based on the design of a field programmable gate array (FPGA) implementation of precise time control sampling measurements (SV) message controller. The implementation of frame loss or error and random number generation, sending SV messages between discrete values of key technology loop regulation etc. The test results demonstrated the feasibility of this technique, smart substation digital measuring device calibration and explore smart substation digital power lay the foundation of measurement scheme.
