Equivalent Circuit of a Power System by Mesh Method

Abstract

The simple equivalence of a power system is obtained in the form of a Lagrangian tree, through the transformation of the circuit matrix where mesh currents are variables and some nodes or elements (load, etc., ) of the system are eliminated, then the equivalence is extremely simplified from the view point of network topology. The application of this equivalence to the calculation of system power flow, and transmission loss is studied.
