摘　　要：以某出海数据中心项目为例,基于ETAP软件对其柴油发电机备用电源系统进行建模,主要分析多电源复杂网络的潮流,以及不同接地方式下的接地短路电流状况及其对保护的影响。ETAP提供的计算结果深入、全面、直观,为设计人员提供重要参考的同时也大幅提高了设计效率。With a case study of an oversea data center,this paper shows the modeling of the standby power supply system of diesel generator by ETAP software.The power flow analysis in multi-source complex network and the short-circuit analysis under various earthing modes are presented with the help of the software,based on which the impacts of earth fault current on the relay protection are discussed.The case study shows that the profound,comprehensive and intuitive results from ETAP can provide engineers with powerful reference and facilitate the design efficiency.
