Advanced process system-on-chips(SoC)are increasingly vital in relay protection,revealing issues previously unconsidered.This includes the single event effects in SoC caused by high-energy particles or alpha particle emissions from chip packaging.Compared with traditional relay protection systems,SoC chip relay protection devices with higher integration,more powerful computing power and smaller size are more suitable for lines with higher requirements for local protection and distributed protection.Although chip-based relay protection devices based on ZYNQ SoC have gradually received attention in recent years,existing research and applications have not considered the failure and hardening of the ZYNQ SoC configuration memory in chip-based relay protection devices.In particular,the configuration memory single event effect may cause the relay protection device to malfunction and fail to achieve the purpose of protection.This study focuses on a ZYNQ SoC model suitable for such applications,employing software fault injection(software fault injection is based on SEMIP core and DPR)to analyze failure modes and effects.It was pointed out that for the SoC configuration memory in the chip relay protection device,the design using DPR has a lower failure degree than the design using SEM IP.
