摘要
运用一套电机过渡过程微机触发装置，在精确控制短路合闸角的情况下，实现发电机端口的短路，然后通过数据采集器实时采集短路电流信号，并在以LabVIEW为开发平台的可视化软件界面上显示和存储整个短路瞬态过程电流波形，并通过与Madab仿真波形进行了对比分析。总结其短路电流的变化规律。
Generator is the key equipment of the power system which the stability of the entire network is straightly influenced by its estate. With exerting a suit of generator transient process computer touch off equipment at precision, this paper controlled short-circuit initial fault current angle to carry out the short-circuit of the generator terminals. Then via data collection equipment gathering short-circuit signals at real time. Finally the entire short-circuit current transient process waves is displayed and stored in the visible software interface on the tap flat roof of LabV/EW. Compared with the Madab simulation wave, we have analysed and summarized the disciplinarian of the short-circuit current.
