摘要
本文用综合矢量法分析并网合闸和线端三相突然短路的冲击电流,导出数学模型,机算结果和实验结果吻合较好。另根据S≈0和参数的特点,得出不太复杂的解析式和时间常数,可看出参数的影响,并算出相当准确的结果。
In this paper, space vectors are used to analyse the surge currents of the asynchonous generator caused by switching rush and 3 -phase sudden short-circuit at the terminals. With the mathematical model derived, the computed curres agree well with the oscillograms. According to s≈0 and the feature of the parameters, analytical expressions for the surge currents and the time constants have been worked out to give insight into the influence of the parameters and fairly accurate calculated results have been obtained.
