仅给出摘要形式，如下所示。本文介绍了动态相量建模技术在不平衡多相电力系统中的应用。该方法是动态相量法的多相推广，适用于非线性电力系统模型。在稳态下，动态相量从交流电路理论中简化为标准相量。该技术产生的结果是非常接近从时域模拟获得的结果。动态相量方面的仿真通常允许比标准时域公式更大的积分步骤。作者提出了模拟的不平衡故障，涉及三相同步发电机连接到一个无限的总线通过传输线，并证明基于动态相量的模型提供了非常准确的描述所观察到的瞬态。
Summary form only given, as follows. This paper presents application of the dynamic phasor modeling technique to unbalanced polyphase power systems. The proposed technique is a polyphase generalization of the dynamic phasor approach, and it is applicable to nonlinear power system models. In a steady-state, the dynamic phasors reduce to standard phasors from AC circuit theory. The technique produces results that are very close to those obtained from time-domain simulations. Simulations in terms of dynamic phasors typically allow larger integration steps than the standard time-domain formulation. The authors present simulations of unbalanced faults involving a three-phase synchronous generator connected to an infinite bus through a transmission line, and demonstrate that models based on dynamic phasors provide very accurate descriptions of observed transients.
