摘　　要：交流站用电系统设计是变电站设计的重要组成部分。文章从保护设备“不拒动”和“不误动”两个基本原则要求、短路电流计算、灵敏度分析及级差配合基础原理出发,基于实际工程案例对其交流站用电系统的配置情况进行详细计算、校验分析,得出其配置情况合理性结论,此计算实例也可给工程实际提供具体参考。The design of the AC auxiliary power system is an important part of the substation design.This paper starts from the two basic requirements of“no refusal to operate”and“no maloperation”for protective devices,short-circuit current calculation,sensitivity analysis and the basic principle of coordinated cooperation.Based on a practical engineering case,the configuration of the AC auxiliary power system is calculated and verified in detail,and the rational conclusion is drawn.The calculation example can also provide specific reference for engineering practice.
