CALCULATION OF AERIAL CABLE SPACER COMPRESSION FORCES IN BUNDLED PHASES DURING SHORT CIRCUIT FAULT
Abstract
The paper presents an approximate method for calculation of electrodynamic resistance parameters of a flexible bus-bar with bundled phases. Comparison of the approximate calculation results with the computer calculations using a FAZA software tool has been given in the paper. An evaluation of permissible aerial cable spacer compression forces for designed modern standard distribution substations of 330 and 550 kV has been provided in the paper. The paper proposes an algorithm for determination of dynamics parameters in a bundled phase with due account of influence pertaining to viscoelastic characteristics of damping spacers.
