摘　　要：本课题针对某造纸企业自备电厂10 kV母线短路电流大,并超过常规断路器分断能力的情况,着重分析了不同短路电流限制方案的原理,比较了其优缺点,提出了发电机出口采用限流电抗器+并联快速限流器的方案,以保证系统的稳定和安全。This research focused on investigating the issue of excessive short circuit current levels(up to 10 kV busbars)for owned power plant in paper mill,which exceeded the conventional circuit-breaker interrupting capacity.A comparative analysis was conducted on the operational princi⁃ples of various short circuit current limiting schemes,with particular emphasis on evaluating their technical merits and practical limitations.Through systematic evaluation,the study proposed implementing a hybrid solution at the generator terminals consisting of a series-connected cur⁃rent limiting reactor combined with a parallel fast current limiting device.This integrated approach was demonstrated to enhance system stability and achieve reliable fault protection under extreme fault conditions while adhering to standard equipment withstand requirements.
