Abstract

Abstract The paper studies main technical requirements for digital substation bay controllers; substantiates the high reliability requirements for file systems running on Flash drives of such devices. An experimental test analysis of the most popular file systems for microcontrollers with limited resources with start-up systems on the STM32F407IGT6 controller have been made. The algorithm of Flash translation layer (FTL) is offered, and also its check on simulation model of the Flash drive and the experimental equipment is carried out. The results of comparing the characteristics of file systems and FTL algorithm are presented.
