摘要
本文介绍了IEC 61660和IEEE Std 946提供的直流短路电流计算方法,针对发电厂直流电源系统短路电流计算,将中国标准DL/T 5044-2014提供的计算方法,与IEC 61660和IEEE Std 946提供的计算方法进行比较,分析中外标准计算方法的差异以及对短路电流计算结果的影响。
This article introduces the short circuit current calculation method of dc auxiliary power supply system on IEC 61660 and IEEE Std 946. Compared the short circuit current calculation method of dc auxiliary power supply system for power plant between Chinese and foreign Standard. A detailed analyzes the differences of short circuit current calculation method between Chinese and foreign standard and its influence to the short-circuit current calculation results.
