摘　　要：针对永磁直线同步电动机垂直运输系统运行特点,为了避免其失步情况的发生,提出了一种基于功角测量的新型保护方案。详细论述了新方案实现的理论基础,策略的实现及功角测量的方法。新方案改变了传统失步保护的观念,有效地提高了系统的可靠性、安全性和运行效率。According to the operation features of the vertical transportation for the permanent magnetic linear synchronous electric motor, in order to avoid the pull -out conditions occurred, a new protection plan base on the power angle measurement was provided. The paper in - detail stated the theoretical base of the new plan, the strategy realization and the power angle measurement method. The new plan had exchanged the conventional pull - out protection conception and could be effectively to improve the system reliability, safety and operation efficiency.
