摘　　要：匝间短路是电抗器运行过程中的常见故障类型,传统的试验技术在面对故障模拟时显示出如模拟不同的短路精度不高、测量信号的采集和数据分析过程繁杂等局限性。提出了一种数模混合试验技术,结合了数字仿真技术的灵活性和物理动模的准确性,能够模拟并计算电抗器在不同匝间短路下的故障特征,较为精确地控制故障模拟时长,并同步分析故障特征从而减少研究过程的时间成本。研究结果表明,通过数模混合试验,可以更准确、快速地分析匝间短路的电气特征,提高识别故障的有效性。Interturn short circuit is a common type of fault in the operation of reactors.Traditional testing techniques shows some limitations in fault simulation,such as low accuracy in simulating different short circuits,complicated process of measurement signal acquisition and data analysis.This paper proposes a hybrid digital-analog experimentation technology that combines the flexibility of digital simulation technology and the accuracy of physical dynamic model,it can simulate and calculate the fault characteristics of the reactor under different inter-turn short circuits,control the fault simulation time more accurately,and analyze the fault characteristics synchronously to reduce the time cost of the research process.The results show that the electrical characteristics of interturn short circuit can be analyzed more accurately and quickly through hybrid digital-analog experimentation and physical testing method and the effectiveness of fault identification can be improved.
