摘要
Abstract
To address the need for distinguishing fault locations in the overcurrent protection of battery discharge regulator(BDR)within spacecraft power supply system,an overcurrent protec-tion optimization design based on fault location is proposed.In the event of a short circuit fault within the BDR,the protection switch is triggered immediately at a lower threshold,thereby minimizing the impact range of the fault.When a short circuit occurs in the bus,the protection switch operates at a high threshold to provide sufficient energy for fault clearance.The proposed optimization design has been validated through simulation and prototype experiments,demon-strating its capability to accurately locate the short circuit faults,adjust the protection threshold,and ensure the normal operation of the power system.关键词
