摘要
主要研究同步电动机定子绕组短路故障。基于同步电动机的理论,建立该电动机的数学模型。在此基础上,建立了同步电动机的仿真模型。基于该电动机的仿真模型,分析和讨论了同步电动机额定负载下正常运行、单相接地、两相短路和三相短路故障,并与解析法计算结果作比较。通过结果比较和分析,验证该电机仿真模型的正确性和合理性,同时也验证了分析方法的有效性和可行性。
This paper mainly studies the short circuit faults of stator windings in synchronous motor(SM).The math model of SM is built based on its theories,and then the simulation model of it is established.This paper analyzes and discusses the faults of SM at rated loading based on the simulation model such as normal operation fault,single-phase ground fault,two-phase short circuit fault and three-phase short circuit fault,and carries out comparison with the analytical calculation result.Through comparison and analysis,the correctness and rationality of SM simulation model is verified,and the effectiveness and feasibility of the analytical method is proved also.
