摘　　要：通过对多相同步整流发电机的短路进行研究,建立了通用的多相同步发电机整流侧的短路特性模型,采用直流侧总的短路电流由所有电压为正的相产生的短路电流叠加的办法,得出了一个简化的实际计算方法与公式。通过与实际短路电流的比较以及其他研究论文计算结果相比较,证明该方法实用、简便、准确,可以作为电力系统保护整定计算的依据,满足工程使用要求。This paper gives a general short circuit model of multi-phase commutated generator by the research on the generator＇ s DC part. The total short circuit current was superposed by all the positive phases＇ current, from that a simplified practical method and formula was derived. Comparison among simulation result, real short current and other articles shows that the method is accurate, simple and practical which meet the demand of engineering and can be used as the foundation of the power system＇s protective tuning calculation.
