Implementation of Low Delay Distribution Terminal Security Protection

Abstract

The security protection function of the existing power distribution terminals is mainly achieved by external encryption devices. Aiming at the serial port problems of large transmission delay and low transmission speed, which is between power distribution terminals and encryption devices, this paper presents a method to realize the low latency security protection of power distribution terminals. By means of the built-in security module of distribution terminals and using the high-speed SPI interface, the data transmission with low latency and high bandwidth can be realized to meet the demand of delay sensitivity for distribution automation services.
