本文提出了处理含无伴电源网络的一种系统分析方法,即改进割集分析法及其对偶——改进回路分析法.对处理含无伴电源网络的其他方法,如改进节点分析法、改进网孔分析法、广义节点分析法及广义网孔分析法,则从网络拓扑观点分别列出了一种系统的矩阵方程,以便于进行计算机辅助分析. In this paper, we propose a system analysis approach to deal with uncoordinated mains networks, that is, improved cut set analysis and its duality-improved loop analysis. For other methods to deal with unaccompanied power networks, such as improved node analysis, improved Mesh analysis method, generalized node analysis method and generalized mesh analysis method, from the network topology point of view, respectively, a system of matrix equations for the convenience of computer-aided analysis.
