在本文中，我们提出并证明了单相和三相电力系统的稳态和瞬态仿真的统一模型和算法的潜力。目前，不同的算法和模型被用于不同的分析，这可能导致不一致-例如，随着时间接近无穷大的瞬态分析与相同条件下的稳态分析不匹配。使用我们的等效电路制定的电力系统，我们提出了一种方法，形成基于物理的模型，可以促进瞬态，平衡的功率流，三相功率流在一个仿真环境。该方法被证明是在一个三相感应电机。现有的行业工具用于验证不同分析的模型和模拟结果。
In this paper we propose and demonstrate the potential for unifying models and algorithms for the steady state and transient simulation of single-phase and three-phase power systems. At present, disparate algorithms and models are used for the different analyses, which can lead to inconsistencies - such as the transient analysis as time approaches infinity not matching the steady state analysis of the same conditions. Using our equivalent circuit formulation of the power system, we propose a methodology for forming physics-based models that can facilitate transient, balanced power flow, and three-phase power flow in one simulation environment. The approach is demonstrated on a three-phase induction motor. Existing industry tools are used to validate the model and simulation results for the different analyses.
