三相交流系统内短路电流的计算

[中文适用范围]： 覆盖高压与超高压电网的短路电流评估需求，旨在帮助工程技术人员在设计与运行阶段准确预测短路状态。文件中的算法考虑了异步电机、同步发电机及变压器等设备的动态特性，确保计算结果贴近实际物理现象。此外，文档还对不对称故障的序分量法进行了阐述，支持多电源网络的分析需求，为系统安全稳定性分析奠定基础。 [外文原描述]： This standard is applicable to the calculation of short-circuit currents: -in low-voltage three-phase a.c. systems, -in high-voltage three-phase a.c. systems with nominal voltages up to 230 kV operating at nominal frequency (50 Hz or 60 Hz). This standardized procedure is given in such a form as to facilitate as far as possible its use by non-specialist engineers.
