摘要
本文根据功率平衡的原则 ,将十二相发电机整流供电系统直流侧线路电阻折算到相应的交流侧各相绕组。在此基础上导出了相应的定子短路时间常数的表达式。借鉴文献 [1 ]的结论 ,进一步导出了考虑线路电阻时十二相发电机整流系统直流侧突然最大短路电流的计算公式 ,说明了线路电阻对短路电流的影响。通过数字仿真及试验进行了验证。
Based on the principle of power balance, the DC-side line resister of a 12-phase synchronous generators-rectifier system is reduced to the corresponding AC-side. Then the short-circuit time constant of the stator is derived. According to [1], the expression of the maximum DC-side short-circuit current taken DC-side line resister into account is obtained, the effect of DC-side line resister is clarified. Comparison between the computed and measured results demonstrates the validity of theoretical approach developed.
