论文摘要
首先,我们提出了一种方法,用于针对将设备模型和网络模型明确分开的通用网络制定不平衡的三相功率流问题。设备模型由(i)内部模型和(ii)转换规则组成。转换规则将设备的内部变量(电压,电流和功率)与通过转换矩阵γ的终端变量联系起来,这些端子变量与网络方程相关。其次,我们将这种方法应用于平衡的三相网络,以使用转换矩阵γ的光谱特性来形式化每一相分析,并证明其对通用网络的有效性。
First we present an approach to formulate unbalanced three-phase power flow problems for general networks that explicitly separates device models and network models. A device model consists of (i) an internal model and (ii) a conversion rule. The conversion rule relates the internal variables (voltage, current, and power) of a device to its terminal variables through a conversion matrix Γ and these terminal variables are related by network equations. Second we apply this approach to balanced three-phase networks to formalize per-phase analysis and prove its validity for general networks using the spectral property of the conversion matrix Γ.
