双绕组发电机交流侧负载对直流侧突然短路电流的影响分析

摘要

The effect of an original AC load on the DC side sudden short circuit current of double winding generator was studied by analyzing the physical conception and phasor diagram,the formula for calculating the short circuit current was simplified,the coudition for calculating the maximum value of DC side short circuit current was given.The correctness of the theoretical analysis was verified by experiments.%通过对物理概念和矢量图的深入分析,研究了3/12相双绕组发电机交流侧负载大小和功率因数对直流侧突然短路电流的影响,简化了短路电流的计算公式,明确了直流侧最大短路电流的计算条件.通过实机试验,检验了理论分析的准确性.
