【摘要】 分析了现有同杆并架双回线路动态物理模型的建模原理,指出了各自存在的主要问题,进而提出了一种新的同杆并架双回输电线路物理模型的建模方法。该方法可准确计及同杆并架双回输电线路各线间互感的差异,更精确地反映同杆并架双回线路故障时的电气量变化特征,仿真实例验证了所提出的建模方法的可行性和正确性。更多还原

【Abstract】 The current double-circuit transmission lines dynamic model developing methods and their shortcomings are analyzed. A novel principle,the minimal mutual impedance sharing principle,which can consider the mutual inductance difference between different phase-to-phase groups is proposed. Based on the parameters of actual 500 kV double-circuit transmission lines on the same tower,the feasibility and validity of the novel principle are validated.更多还原
