Solution Method for the Roll-Circuit Model of Symmetrical Three-Phase Circuits

Three-phase circuits are a crucial component of electrical engineering technology and an important form of circuit modeling. This paper comprehensively reviews the knowledge of symmetrical three-phase circuits. Based on the construction of the superposition number system-roll number and its operational rules, the concept of the symmetrical three-phase circuit roll-circuit model is defined. By improving the structural composition, expression methods, and circuit analysis techniques, a systematic framework for analyzing symmetrical three-phase circuit roll-circuit models is proposed. Application examples of three-phase circuit roll-circuit model analysis are also provided to enhance the knowledge system of circuit analysis.
