摘　　要：随着水泥行业的迅速发展,水泥线的生产规模、用电负荷不断增加,且外部供电电源规模增加极为迅速,导致水泥工厂供配电系统短路电流持续性升高,对电力系统及工厂内部设备的运行安全构成严重威胁。文章以印尼巴亚项目实例,分析各种短路电流限制方案,重点介绍了快速限流器在该项目多电源系统短路电流限制的应用和特点等。With the rapid development of cement industry, the production scale and power load of cement line are increasing, and the scale of external power supply is increasing rapidly, which leads to the continuous increase of short-circuit current in power supply and distribution system of cement plant, which poses a serious threat to the operation safety of power system and internal equipment of the plant. Based on the example of Indonesia Baya project, this paper analyzes various short-circuit current limitation schemes, and focuses on the application and characteristics of the fast current limiter in the short-circuit current limitation of multi power system of the project.
