The Use of Mode Components for Calculating Steady-state Processes in Long or Short Multiphase Lines

Ivars Dumins

Abstract


The calculation of steady-state processes in the non- symmetric multiphase long or short line by using the distribution of the solution for the voltages differential equations in mode components is considered. The matrices of integrations constants can be obtained if the voltages or the currents at the beginning of the line and the matrices of input are known. The elements of these matrices are to be calculated directly from the definition. The distribution of the voltages along the specific 4-wire line is calculated. The fault of the phase to neutral is calculated in a specific 4-wire line. The method can be recommended for the calculation of short lines too. 


Keywords:
