A Matrix method for the Simplification of Linear Passive Networks

행렬법에 의한 선형수동회로의 간략화법

A new method for simplifying linear, bilateral and passive networks is presented, and the principle employed is based upon the elimination of mutual impedance and floating nodes of the metwork by introducing incidence matrix notations and bus admittance matrices. The method suggested is, particularly, suited for machine computations and applycable for reducing the calculation time in power system short-circuit and load-flow studies with good results.
