【摘要】 国际电工委员会(IEC)于2001年新制定的短路电流计算标准同我国当前普遍使用的传统算法相比,有很 大程度的变化,虽然计算项目多,但概念明确,算法简单扼要,阻抗修正具有科学性,其计算的短路电流接近发电机额 定输出时的短路电流。鉴于我国电力行业与国际接轨的必然趋势,IEC新标准被审批为我国正式的国家标准只是时 间的问题。更多还原

【Abstract】 The calculation standard for short-circuit current issued by the International Electrical Committee (IEC) in 2001 has great changes comparing to the traditional standard widely used in China. The calculation items in IEC standard are more, while their concepts are clear with simple calculation method, impedance correction is scientific and calculated short-circuit current is close to the short-circuit of the rated output of the generator. It is a necessary tendency for power industry of China to link with the world and IEC new standard will be proved to be the formal national standard in China.更多还原
