A step-by-step method for Z-loop construction using graph theory and topology for power system studies

This manuscript will provide a step by step method on how a graph theory and topology can be utilized to construct a Z-loop matrix for the study of faulted power systems. The growing demand for reliable electrical power supply has forced the pace developments in electrical power system analysis using computer. In this, power system analysis plays a significant role for the analysis of faulted power system, eventually for power system protection and control.
