摘　　要：对电解铝厂的供电系统进行了详细分析,设计了一套完整的供电保护方案.该方案通过对电解铝厂的供电系统框架和各用户设备组成情况进行分析,获取各用电模块的供电保护阈值.在电解铝厂供电系统出现故障时,能够做出正确的继电保护,在确保对故障电路隔离的同时,尽可能降低对整个供电系统的影响.文中重点阐述了不同故障和恢复要求条件下的供电保护方案,并对每一种方案的实现要点进行了分析.Has carried on the multianalysis to the electrolysis aluminum manufacturer power supply system, has designed a set of complete power supply protection plan. This plan through carries on the analysis to the electrolysis aluminum manufacturer power supply system frame and various subscriber equipment composition situation, and then gain the electricity module power supply protection threshold value respec- tively. When the electrolysis aluminum manufacturer power supply system presents the breakdown, which can make the correct protection, while guaranteed isolates to the breakdown electric circuit, reduces as far as possible to the entire power supply system influence. In the paper elaborated with emphasis the different breakdown and restores under the request condition the power supply protection plan, and has carried on the analysis to each kind of realization plan.
